GroundWorx™ Basics Static Conductive Poured ESD Epoxy Floor Coating | ANSI/ESD S20.20-2014

New concrete floors should be allowed to cure a minimum of thirty days. Application to floors colder than 60 F is not recommended. Floor surfaces must be free of any release agents, curing compounds, salts or efflorescence before coating. Sweep and then wash floors with an appropriate cleaning product to remove oil, grease, and soil. Follow by etching surface with an etching solution, and then thoroughly rinse with clean water.  Ideal preparation on concrete is to rough up floor mechanically with grinder for a 80 to 100 grit sandpaper like feel.

For concrete surfaces with existing epoxy

Catalyzed GroundWorx™ has a working time of 40+ minutes and therefore, prepare only the quantity necessary for immediate use. Add pre-measured catalyst to epoxy base. Stir gently until the catalyst has been thoroughly mixed in. Allow catalyzed GroundWorx to stand for 2 minutes.

The initial coat coverage rate will vary depending on surface applied to.  On bare concrete that has been roughed up, first coat applied at 250-300 sq’.  On smooth non-porous surface such as VCT or tile first coat will cover approximately 400-500 sq’/gallon.  Allow the initial coat to dry for 5-7 hours until dry to the touch then apply a second coat. Second coat coverage is approximately 500 sq’/gallon. A 3rd coat is strongly recommended when applying to bare concrete and can be applied at 500 to 600 sq’/gallon.  For all projects a 3rd coat can be applied for increased physical durability of the GroundWorx coating applied at 500-600 sq’/gallon.

Under normal curing conditions, the finished floor may be opened to light traffic after 12 hours and full foot traffic in 24 hours.  Heavier traffic in 36 hours and complete curing with maximum durability and chemical resistance will take 5-7 days

Electrical Grounding   The GroundWorx SF coating must be grounded to an earth ground once every 1,000 square feet for proper static dissipation. The 1,000 sq’ assumes a continuous surface area.  If there are multiple rooms not connected to the main area, then will need a copper grounding strip for each isolated area even if less than 1,000 sq’.

The EOS/ESD Association provides instruction for proper grounding of ESD equipment and floors. We offer the option to include with the GroundWorx Epoxy, a 1/2 inch-wide copper grounding strip for grounding to earth grounds. Copper is 1.4 mil thickness (2.6 mil thickness with the conductive adhesive backing.

See the following guide on how to properly ground the GroundWorx SF Epoxy for your floor coating system:  HOW TO GROUND ESD COATINGS

If floor has been previously coated, a small area should be cleaned, roughed up by screen disking with an 80 Grit screen. A single application of GroundWorx – SF should be applied over the old coating and allowed to dry. The trial area should be tested for adhesion, lifting, etc. Any areas of the existing coating which display poor adhesion should be stripped. Wash the stripped areas, acid etch, and rinse thoroughly. Allow the floor to dry.

Catalyzed GroundWorx – SF should be used within six hours of mixing, therefore, prepare only the quantity necessary for immediate use. Add premeasured catalyst to epoxy base. Stir gently until the catalyst has been thoroughly mixed in. Allow catalyzed GroundWorx – SF to stand for 5 minutes. Apply catalyzed GroundWorx – SF with a short nap roller in thin, uniform coats.

The initial coat will cover approximately 400-500 ft2 per gallon. Allow the initial coat to dry for 5-7 hours, and then apply a second coat. Second coat coverage is approximately 500-600 ft2 per gallon.  Not required but 3rd thin coat can be added for increased durability.

NOTE: This product is not recommended for applications that experience reoccurring standing water. Finished floors may be opened to light traffic, under normal curing conditions, after 12 hours. Complete curing with maximum durability and chemical resistance will take 5-7 days.
