2. Subfloor Recommendations

A. Subfloor Grade Levels

IMPORTANT NOTE: Moisture testing as per ASTM F 1869 and/or ASTM F 2170 is mandatory.

The following example displays the three types of subfloor grade levels:

Above Grade – An acceptable above grade floor is a concrete or wood substrate. Suspended – An acceptable suspended floor is a concrete or wood substrate with a minimum of 18” (460mm) of well-ventilated air space below. It is recommended that an effective moisture vapor retarder be placed upon the ground beneath the air space.

On Grade – An acceptable on grade floor is a concrete substrate partially or completely in contact with the ground. Properly constructed, the concrete slab will be suitably prot ected from moisture penetration by planned water drainage and incorporated an effective moisture vapor retarder.

Below Grade – An acceptable below grade floor is a concrete substrate in direct contact with the ground. Properly constructed, the concrete slab will be suitably protected from moisture penetration by planned water drainage and incorporated an effective moisture vapor retarder.

B. Wood Subfloor Recommendations

Types of Wood Subfloors

Single Plywood – This type of subfloor construction shall be installed according to EWA “Engineered Wood Association” (formerly the APA) specifications. EWA underlayment GRADE plywood shall be used and installed according to EWA recommendations.

NOTE: Not recommended wood subfloors: tempered hardboard, untempered hardboard, particle board, wafer board, strand board, fire retarded plywood and board.

Precautions - Wood Subfloors

StaticWorx rubber flooring shall not be laid on wood subfloors that are directly in contact with concrete subfloors on or below grade, even if built on sleepers. All suspended wood floors should have adequate under floor ventilation. It is recommended that an effective moisture vapor retarder be placed on the ground beneath the air space.

Preparation

NOTE: All responsibility for warranties and performance rests with the plywood manufacturer.

C. Concrete Subfloor Recommendations

Types of Concrete Subfloors

Many different types of concrete subfloors exist, the only recommended concrete subfloor is American Concrete Institute “ACI” 302 Class 4, 5, & 6. Light weight concrete, less than 115 lb/ft3 (1841 kg/m3), may have such low strength that it is unsuitable for covering with resilient flooring unless 1 in. (25 mm) or more of standard weight concrete, generally 140 lb/ft3 (2241 kg/m3) or more, is used as a topping.

NOTE: Light weight concrete can take a lot longer to try.

A permanent effective vapor retarder with a low permanence (less than 0.1) having a minimum thickness of 10 mils (ACI 302), shall be placed directly underneath the concrete slab.

Precautions - Concrete Subfloors

The slab temperature of concrete subfloors shall be between 68°F + 5°F. Slab temperature is critical to the set-up time of adhesive. A slab temperature below 68°F will slow down the initial tack of the adhesive, making it necessary to re-roll the flooring at 60 minutes, and again at 90 minutes. A slab temperature above 75°F will increase the initial tack of the adhesive, making it necessary to re-roll the flooring within 30-45 minutes rather than the recommended 60 minutes.

An acceptable concrete subfloor shall also meet the following requirements:

  • All concrete subfloors shall be dry, clean, smooth and structurally sound. 

Subfloors shall be tested using both of the following methods:

Preparation

WARNING! Materials should not be installed over building expansion joints.

NOTE: The aforementioned recommendations concern only the bonding characteristics of StaticWorx flooring products to concrete subfloors. The performance of the subfloors should be established according to industry standards (American Concrete Institute “ACI” 302 Class 4, 5 & 6).

Underlayment (Leveling Compounds)

If the subfloor surface is noticeably uneven or out of level, then it should be properly leveled by an experienced underlayment contractor. The leveling materials must be portland cement based and should provide a minimum 3,500 PSI compressive strength (ASTM C 109) and sufficient bond to existing subfloor surface (i.e. Ardex, Laticrete, Duralox, Mapei, or equivalent) and shall be installed as per the manufacturer’s instructions.

Preparation

All concrete subfloors shall be prepared according to ASTM F 710 Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring.

Adhesive Bond Test

This is recommended to determine the compatibility of the adhesive to the pre-prepared subfloor and can be a useful indicator if the moisture results are marginal. Use the specified approximately 50′ apart throughout the area. Areas next to walls or other light traffic areas should be selected for the bond test. Tape down the perimeter of the flooring to prevent drying of the adhesive at the edges. After a minimum period of 72 hours the flooring should be pulled from the subfloor. If an unusual amount of force is required, the bond could be considered sufficient.

NOTE: If the subfloor is radiant heated, contact StaticWorx, Inc. for correct installation recommendations. 

D. Steel Subfloor Recommendations​

For information about acceptability and preparation of steel subfloors, please contact StaticWorx, Inc. Technical Department at 617-923-2000.

E. Existing Subfloor Recommendations​

Permanent Floor Finishes
Terrazzo, Quarry Tile, Ceramic Tiles, Marble

Types of Bonding Agents​

  1. Mud Cement Setting – This is a suitable bonding agent for permanent floors. Application may be made over such a subfloor.
  2. Epoxy & Urethane Coatings – This can be a suitable subfloor. The bond must be carefully checked. Look for loose areas and check for proper bond. If an Epoxy coating has failed, please contact StaticWorx, Inc.
  3. Thin Set – This is not a suitable bonding agent. Remove tiles and clean the surface.

Preparation

Non-Permanent Floor Surfaces

NOTE: These ARE NOT acceptable subfloors. They are not permanent, and bonding is difficult. Any installation over these floors becomes the responsibility of the owner. Vinyl Asbestos Tile (VAT), Vinyl Composition Tiles (VCT), Asphalt Tile, Vinyl Tile & Sheet Goods.

CAUTION: Existing floor covering may contain asbestos (federal, local and state restrictions shall be followed).

3. Adhesive Recommendations

FlooringAdhesiveTrowel SerrationAdhesive Coverage
StaticWorx Rubber & VinylPressure Sensitive1/16 x 1/16 x 1/16″ square-notch180-200 SF
Statbond1/16 x 1/16 x 1/16″ square-notch125-150 SF
2-Part Conductive EpoxyPlease contact StaticWorx

Open Time

The open time will vary depending upon temperature, air flow and humidity.

Statbond adhesive should have a minimum of 10 minutes open time (square-notched). The ideal time to lay the flooring into the adhesive is best described as follows:

Semi-Wet The adhesive must be able to transfer to your finger tips with a light touch and just start to string while the core of the serrations remains wet (resulting in full adhesive
transfer).

NOTE: This method can only be used on a porous surface.

2-Part conductive epoxy adhesive should have a minimum of 20 minutes open time. The ideal time to lay the flooring into the adhesive is best described as follows:

When the adhesive first starts to tack-up or becomes sticky.

4. Installation Checklist​

Before work is begun, every site should be inspected for items listed below.

Equipment Checklist

5. Sheet Goods Installation

Material Layout/Fitting for Sheet Goods

CAUTION: If seams are not cut dry beforehand, peaked seams may occur from lack of adhesive due to removal of some adhesive with the tapered edge/waste.

NOTE: The flooring pattern does not always continuously flow into the tapered edge, so check before cutting to
remove the tapered edge and be sure to maintain the correct flow of the flooring pattern.

When double cutting the seam, use a straight edge as a guide. Position the straight edge about 1/2” (0.5”) from the top edge. Cut through the top sheet and approximately 3/4 of the thickness of the bottom sheet using a utility knife and a sharp straight blade. When making the cut, hold the utility knife as vertical as possible.

To remove the tapered edge use one of the two methods above [under Section Method One (6a. or 6b.)].

Adhesive Application

WARNING!

Be prepared to protect the flooring during and after the installation from sun, moisture, and other construction trade (at least until adhesive has cured), if required, by covering 1-2 days with Masonite or plywood, insuring all joints are taped to prevent debris from becoming entrapped underneath and causing damage.

CAUTION: When spreading the adhesive (after the seams have been cut), it is vitally important that the material not move. If necessary, place weights on the material so that no movement will occur as you spread adhesive. Overlapping the adhesive may telegraph through the flooring.

Semi-Wet Method

TOP TIP: Using carpet off-cuts and double sided tape, cover the roller to help ensure you remove all air pockets from any dips in the substrate, and avoid a punch list.

7. Additional Installation Info

In rooms up to 1000 sq. ft. in size, a copper strip must be applied to the subfloor and extended to a predetermined grounding point (can be connected by your flooring contractor or a qualified electrician). In rooms larger than 1,000 sq. ft. additional grounding points shall be defined and copper strips installed as mentioned above.

StaticWorx specified adhesive must be used for the installation of StaticWorx ESD protection flooring, using
recommended adhesive and trowel serration, refer to section 3, Adhesive Recommendations.

PLEASE NOTE: StaticWorx flooring products have been developed for indoor installation. StaticWorx floor coverings are not recommended for installation in outdoor applications or in particularly wet areas such as showers, swimming pools, etc.
