Technical Information

Prior to Installation, Chelsea Plank Flooring® and Restoration Series Plank® flooring needs to be acclimated to the environment of the installation site. Proper acclimation and installation work hand in hand to ensure the beauty of your plank floor upon completion and for many years in the future.

PURPOSE
Hardwood flooring is hygroscopic. This means the moisture content of your plank floor will increase or decrease with changes in the relative humidity of the installation environment, both before and after installation.

If the moisture content of the planks increases, they will expand in size. Conversely, if the moisture content of the planks decreases, they will contract in size. The purpose of acclimation is to expand or contract the size of the planks to best match the current and future installation environment, prior to the installation. As such, there is no pat answer for how long plank flooring should acclimate. Successful acclimation should be job specific and include a good measure of common sense.

HUMIDITY CONTROL
The Frame Industries manufacturing facility is maintained at a relative humidity ranging from 35 to 60%. Ideally, the installation environment will be maintained at the same humidity range. Please be aware the installation environment includes the immediate living area as well the space located directly below the living space to include basements and crawl spaces. To maintain the 35 to 60% recommended relative humidity, Frame Industries suggests installation and use of the following equipment:     

To prevent relative humidity levels above 60%:Air conditioner (of proper size and in working order)

• Dehumidifier (if required)

To prevent relative humidity levels below 35%:

• Humidifier (of proper size and in working order)

In addition to the above listed equipment, Frame Hardwoods strongly recommends monitoring the installation environment with a hygrometer to ensure proper relative humidity levels are maintained.

ACCLIMATION EXAMPLES

• If the installation environment is humidity controlled, acclimation is unnecessary and the plank flooring may be installed immediately.

• If the installation environment is not humidity controlled and located in an arid region, allow the plank flooring to acclimate for 7 days. This will allow the planks to shrink in size, preventing future gapping of the floor.

• If the installation environment is not humidity controlled and located in a mixed arid region, allow the plank flooring acclimate for 7 days if it is the wet time of the year (above 60% relative humidity). Install the plank flooring immediately if it is the dry time of the year (below 35% relative humidity).

• If the installation environment is not humidity controlled and located in a mixed humid region, allow the plank flooring to acclimate for 15 days if it is the wet time of the year (above 60% relative humidity). Install the plank flooring immediately if it is the dry time of the year (below 35% relative humidity).

• If the installation environment is not humidity controlled and located in a humid region, allow the plank flooring to acclimate for 15 days. This will allow the planks to expand in size, preventing future cupping and/or buckling.

• If the installation environment is not humidity controlled and located in a tropical region, allow the plank flooring to acclimate for 30 days. This will allow the planks to expand in size, preventing future cupping and/or buckling.

The examples listed above are for reference only and do not cover all possible applications. If you have additional questions or concerns, please contact Frame Hardwoods, Inc. at 734-433-1023.

This installation guide is intended to aid in the installation of Chelsea Plank Flooring® and Restoration Series Plank® flooring. In addition to this guide, installation should be performed in accordance with NWFA and NOFMA installation standards for 3/4" hardwood plank flooring.

CONSIDERATIONS

General: First, it is important to determine the intended installation space is suitable for a quality plank flooring installation. The primary rule of hardwood flooring is that wood and water don't mix with water defined as any type of moisture from standing puddles, to the moisture content of the subfloor, to the current and future humidity levels of the space. As such, the intended installation space must be fully enclosed and environmentally controlled to maintain humidity levels between 35-60%. In addition, unless extraordinary precautions are taken with regard to moisture and humidity, solid hardwood flooring should never be installed below grade.

Location and Life Style: Hardwood plank flooring is extremely versatile and depending on the specie, lumber cutting technique and plank width may be used in applications ranging from summer lake cottages in the mid-west to environmentally controlled living spaces for allergy sufferers. That said, some floor styles may work well for the intended installation space while others may not. Disregarding the natural tendencies of the different types of plank flooring strictly for design consideration may cause disastrous results. Thoroughly discuss your living space requirements with the sales person prior to selecting your plank floor style. Marriage of design and practicality is key to a long lasting floor and happy owner. If you are concerned with your application, please contact Frame Industries at 734-433-1023 for assistance.

New Construction: When installing hardwood flooring in a new structure, moisture emissions from concrete, drywall and paint cause elevated humidity levels for an extended period of time. Acclimation and installation of the plank flooring should not occur until the relative humidity of the installation space is controlled between 35-60%.  Installation of high capacity dehumidifiers is strongly recommended.

INSTALLATION SPACE REQUIREMENTS

Subfloor: The subfloor must be properly secured to the floor joists and flat with no deflection greater than 3/16" over any 10' span. If the subfloor isn't properly fastened to the joists or uneven areas are not corrected the plank floor will squeak and/or become damaged over time. The moisture content of the subfloor at the time of installation must be between 8 - 10%. Higher moisture content may cause dimensional changes to the planks resulting in cupping and/or buckling of the floor.

Suitable subfloor construction
Plywood or OSB
I) Truss/joist Spacing less than 16" on-center
a) 5/8" CD Exposure 1 plywood (4x8 sheet)
b) 23/32" OSB Exposure 1 (4x8 sheet)

II) Truss/joist spacing of 16" to 19.2" on-center
a) 3/4" CD Exposure 1 plywood
b) 3/4" OSB Exposure 1

III) Truss/joist spacing of 19.2" to 24" on-center
a) 7/8" CD Exposure 1 plywood
b) 1" OSB Exposure 1

Solid BoardI) Truss/joist Spacing of 16" on-center
a) 1" x 4 to 6" width, Square edge, kiln dried coniferous lumber
b) The boards must be laid diagonally over the joists
c) The board ends must be cut parallel to the center of the joists
d) The boards must be face-nailed with 7d threaded or 8d common nails
c) The board ends must be cut parallel to the center of the joists
d) The boards must be face-nailed with 7d threaded or 8d common nails

Concrete: Slab - level and cured
a) Requires special adhesive and adhesive application

II) Lightweight (radiant heat) - level and cured
a) Requires special adhesive and adhesive application

Humidity Level and Control: The relative humidity of the installation space must be maintained between 35 - 60%. The relative Humidity should be measured using a hygrometer under the same temperature and humidity conditions in which the installation space will be maintained after the flooring has been installed. Installation of high capacity dehumidifiers is strongly recommended.

Basement / Crawl Space: The basement / crawl space must have effective vapor barriers, ventilation and dehumidification. The relative humidity must be maintained between 35 - 60% at all times. If the relative humidity is not controlled, elevated humidity levels will cause the floor to cup and / or buckle.

Acclimation: 

Acclimation is a critical aspect of a quality plank flooring installation. Please read the Acclimation Instructions located above. If there are any questions regard acclimation, please contact Frame Industries at 734-433-1023.

Glue Assist Installation Method:

Frame Industries does not suggest utilization of the Glue Assist installation method for any Chelsea Plank Flooring products, no matter the width. Glue Assist can prevent cupping. However, it does not prevent hardwood from expanding when it absorbs moisture.  

We feel cupping is the floor naturally telling the homeowner there is a moisture problem that needs to be addressed. If the source of the moisture is identified and mitigated, mild to moderate cupping will correct itself naturally.

Conversely, if cupping is prevented and the floor is forced to expand laterally, it may cause structural damage. As example, the width of a 20’ wide Hickory installation will expand by 1” for every percentage point of moisture the floor absorbs after installation.

INSTALLATION

1) Set up the "cutting area" in the garage or a job trailer to avoid damaging the installed floor or introducing excessive sawdust to the installation space.
2) You should wear clean, soft soled shoes while installing plank flooring.
3) Use traffic mats and pads to avoid dents and scratches.
4) Clean up dust, nails, cut offs, etc. everyday to prevent damage to the installed portions of the plank floor.
5) Plank flooring should be installed perpendicular to the floor joists. This is necessary to prevent squeaks caused by deflection of the subfloor between the joists.
6) The subfloor must be fastened to the joists every 9" using screws. Per many building codes, the subfloor must also be glued to the joists in new construction.
7) Use a vapor retardant material between the floor and subfloor such as 15# roofing felt or papers specifically designed for solid hardwood flooring installations like All Globe SVS or Aquabar. Do not use red rosin paper, vapor barrier materials or products designed for laminate floor noise mitigation.
8) The planks should be fastened to the subfloor with 16 Gage Powercleats of the correct length for the specific floor construction.
9) The fasteners are driven through the tongue of the plank at a 45° angle with the groove of the next plank covering the fastener.
10) Each plank should be inspected for defects prior to installation.
11) The planks are fastened to the subfloor. Through nailing to the joist is not necessary.
12) The first and last fastener of each plank should be located 3" to 5" from the planks ends.
13) The fasteners should be installed approximately 10" apart.
14) Leave a 3/8" expansion gap between the flooring and wall and any other fixed objects like cabinets and support posts to allow for seasonal expansion. 
15) The starter course must be perfectly straight and, for best results, anchored with 2", 15ga finish nails to ensure it does not move.
16) Long planks should be used in the starter course which is typically is positioned next to the longest and straightest wall of the installation space.
17) Start and finish each row with a square ended "cut-off" plank to best utilize the planks and prevent their use in the center of the floor.  
18) Prior to fastening, experiment with plank sizes and positions to minimize scrap, blend colors, and ensure the end joint stagger is pleasing to the eye.  
19) To complete the plank floor, conceal the expansion gap with base board, shoe mold or trim.
20) Use caution when moving heavy objects over the newly installed plank floor. Small, hard appliance casters and dolly wheels can permanently "track" the floor.

Important Note: 
Standard hardwood flooring nail and staple guns should have the "Factory Finished" shoe installed to the tool. The "Factory Finished" shoe shifts the impact of the hammer blow from the beveled edge of the plank to the front of the tongue to prevent plank damage during installation  If a "factory Finished" shoe is unavailable, add a thin felt pad to the plate of the gun and avoid using the plate to drive planks together.

Special Applications

Concrete / Light Weight Concrete: 
The flat and true milling of Chelsea Plank Flooring® and Restoration Series Plank® is ideal for glue down applications. Installation of plank flooring to concrete must follow NWFA specifications relating to concrete and site conditions as well as the adhesive manufacturer's specifications and instructions. For additional information regarding NWFA specifications and adhesive manufacturers please follow the links provided below.

Radiant Heat: Chelsea Plank Flooring® and Restoration Series Plank® may be installed over radiant heating systems provided the surface temperature of the subfloor does not exceed 85° F (30° C). Installation should be performed in accordance with the heating system manufacturer's requirements. In addition to the manufacturer's requirements, we require the use of a whole house humidification system to maintain relative humidity between 35-60%. This will minimize gapping between the planks and possible grain separation during the heating season.

In most cases, to avoid damaging the tubing of the radiant heating system, plank flooring is secured to the subfloor with adhesive. Check with the manufacturer of the radiant heating system as well as the manufacturer of the adhesive to ensure the two systems will work in conjunction for your application. For additional information regarding adhesive manufacturers, please follow the links provided below.

Glue Assist Installation Method: Frame Industries does not suggest utilization of the Glue Assist installation method for any Chelsea Plank Flooring products, no matter the width. Glue Assist can prevent cupping. However, it does not prevent hardwood from expanding when it absorbs moisture.  

We feel cupping is the floor naturally telling the homeowner there is a moisture problem that needs to be addressed. If the source of the moisture is identified and mitigated, mild to moderate cupping will correct itself naturally.

Conversely, if cupping is prevented and the floor is forced to expand laterally, it may cause structural damage. As example, the width of a 20’ wide Hickory installation will expand by 1” for every percentage point of moisture the floor absorbs after installation.

HARDWOOD FLOORING AND WATER

DON’T PLAY WELL TOGETHER

Hardwood flooring is like a sponge, when it absorbs moisture it expands in width and when it depletes moisture it contracts in width.

To avoid the damage associated with expansion (Cupping, Buckling, Compression Fractures) and contraction (Gapping, Checking), you MUST control the quantity of moisture that comes into contact with your hardwood floor.

Expansion is caused by anything classified as “wet”. The list of “wet” items includes but is not limited to:

·        Water supply line failures

·        Drain line failures

·        Sink or toilet overflows

·        Heavy or repeated spilling

·        Pet urine or drool

·        Wet mopping

·        Steam mopping

·        High humidity level of the living environment

·        High humidity level below the living environment

·        Flooding of basement or crawlspace

Contraction is caused by anything classified as “dry”. The list of “dry” items includes but is not limited to:

·        Low humidity level of the living environment

·        Low humidity level below the living environment

HUMIDITY

Improper humidity control is the most common cause of hardwood floor damage. For best results, maintain a relative humidity level between 35-60% (both above and below the floor).

We also strongly suggest the use of a stand-alone Hygrometer even with very sophisticated HVAC systems. We do this for two reasons - 1) A Hygrometer is a good backup to ensure your HVAC system is operating properly. 2) Confusion exists between settings and readings on some HVAC systems.

PLEASE,

DO NOT RUIN YOUR BRAND NEW

Preventive Care

• Appliance Movement
  Thoroughly clean your plank floor prior to moving appliances to prevent scratching caused by sand or grit.
  Place a clean piece of carpet, pile side down, under the appliance and move the appliance slowly across the floor into position. If moving the appliance for service or cleaning, roll the appliance onto a piece of Masonite or Luan to prevent grooving or tracking of the floor.

• Furniture Movement
  Thoroughly clean your plank floor prior to moving furniture to prevent scratching caused by sand or grit.
  As your furniture may have inadequate, damaged or missing protective slides, we strongly suggest removal and replacement of all existing slides with high quality felt furniture glides. This prevents damage from initial furniture placement as well as damage from furniture movement for cleaning and re-arrangement.
  Casters can cause severe damage to plank flooring. Though precautions cannot ensure casters will not damage your plank flooring, we strongly suggest replacement of all steel, wood and plastic casters with high quality, non-marking, soft rubber or Polyurethane casters as well as the use of rubber backed protective roller mats.

• Door Mats and Rugs
  Place quality rubber backed (not jute) door mats, both on the inside and outside of each exterior door location of your home to protect your plank floors from abrasive sand and grit.
  Placing rugs in high traffic areas will help preserve the gloss level of your plank flooring.

• Humidity Control

  To prevent damage to your plank flooring, maintain the humidity in your home between 35% and 60%. To maintain the recommended humidity levels, Frame Industries, Inc. strongly suggests year around humidity control via a humidifier and dehumidifier. Use of a Hygrometer is also essential in maintaining correct humidity control.

Cleaning Care

• Liquids and Water
  Water and other liquids can cause your floor to warp and buckle. Never use a steam cleaner and never mop your floor with water. Make sure to wipe up spills immediately.

• Grit and Sharps
  Sand, dust and dirt can scratch your plank floor. Clean sand and dirt from your plank flooring immediately, especially sand and dirt located in high traffic areas.

• Wax and Oil

  Your plank flooring includes an eight-layer polyurethane, no-wax finish. Use of wax, oil or oil soap is as likely to damage your floor, as it is to help. Often these products will make your floors look wonderful after the first application. However, after multiple uses, the product build up becomes cloudy and the beauty and color of your plank floors is lost until the build up is removed.

• Damp Sponge
  Clean spills and sticky messes with a well-wrung damp sponge, soft cloth or paper towel.

• Vacuum or Sweep
  Vacuum or sweep the floor to remove any sand or grit from the floor surface and beveled edges between the boards.
  If vacuuming, do not use a vacuum with a rug beater bar, use an electric broom or stick vacuum.
  If sweeping, use a broom with soft bristles.

• Dry and Damp Dusting
  Dry dust your floors with a micro fiber dust mop.
  To damp dust, lightly mist the section of floor you are damp dusting with a quality hardwood floor cleaner or window cleaner.

Over time, a plank or several planks may become damaged beyond acceptable appearance. In that event, the most effective visual repair is to replace the damaged plank(s). The following guide illustrates how to properly remove and replace a damaged plank.

**Plank replacement is a moderate to difficult procedure that should only be attempted by a skilled craftsman or an individual confident in their woodworking abilities**

 Required tools and materials:

• Circular Saw

• Fine Tooth Carbide Blade (new)

• Straight Edge

• Pry Bar (small)

• Wood Chisel

• Utility Knife

• Sanding Block (120 grit sandpaper)

• Color Match Stain Marker (if required)

• Clear Semi-gloss Polyurethane

• Foam Paint Brush (small)

• Wood Adhesive

• NOTE: The Festool saw and guide channel used in this illustration is the best tool set-up for this repair. http://www.festoolusa.com

·       UV curing is a photochemical hardening process as opposed to an evaporative drying process.

·       With no evaporation, UV finishes are 100% solids based as opposed to water or oil based.  

·       Our finish is a mix of urethane and acrylic.

·       The urethane allows the finish to flex and maintain adhesion during expansion and contraction.

·       The acrylic increases the hardness of the finish.

·       We apply 7 layers of finish to our satin or eggshell gloss level products.

·       We apply 6 layers of finish to our matte gloss level products.

·       When completed, these layers bond into a single layer of finish.

·       Aluminum Oxide is included in the top layer of our satin and eggshell gloss level products.

·       Aluminum Oxide adds additional abrasion resistance to our higher gloss products.

·       There is no formaldehyde in our finish, and it does not outgas VOCs.

LIMITED RESIDENTIAL WARRANTY

FOR

CHELSEA PLANK® FLOORING

PRE-INSTALLATION INSPECTION

Frame Industries has developed and utilizes a stringent quality control program in the manufacture of Chelsea Plank® Flooring. It is important to understand that these products are produced from natural materials containing a wide variety of color, grain, and character. The products are produced using a high-speed manufacturing process and therefore it is possible each box may contain a small percentage of defects (normally less than 1%). Due to these facts, the flooring installer should inspect each plank with regard to defects or any undesirable character that the end customer may not want. The actual flooring to be installed should be reviewed with the installer and customer both present. Any defective planks may be returned for replacement with the dealer where the flooring was purchased.

VARIATION BETWEEN LOTS

It is possible a single job can contain flooring from two or more runs or lots. As different batches of lumber will contain different amounts of character and/or color within the same grade, different lots may contain varying concentrations of color and/or character. When an installation includes multiple lot numbers, it is imperative the installer verify the different lot numbers will blend harmoniously, prior to installation.
