I. GENERAL INFORMATION

Product # 633Novolac Epoxy Coating System consists of Product #899 Epoxy Primer followed with two coats of Product #633 High Build Chemical Resistant Novolac Epoxy Floor Coating. Product #633 High Build Chemical Resistant Novolac Epoxy Floor Coating is available in pigmented finish only.

Before installation read Do with epoxies and Don't do with epoxies. 

II. SURFACE PREPARATION

Surface Preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared to a minimum surface profile of CSP-2 as outlined in Epoxy.com Surface Preparation Procedures. Specific attention should be paid to the following:

A. Concrete Placement--An efficient vapor barrier should be under slabs on or below grade to prevent moisture migration. A moisture vapor treatment may be necessary.

B. Curing and Finishing Techniques of the Concrete Substrate

C. Age of Concrete

D. Previous Contamination of the Substrate

E. Present Condition of the Substrate Also, the temperature and humidity conditions of the area to receive the flooring system should be checked. An optimum room temperature of 75°F with a minimum slab temperature of 60°F is required for proper cure of the resin flooring system.

III. MATERIAL QUANTITIES

A. Guideline System Requirements for 1000 ft 21-27 Mils Product #2 High Build Chemical Resistant Epoxy Coating System Qty./ 1000 ft

1. Product #899 Epoxy Primer 4-5 gallons

2. Product #633 High Build Chemical Resistant Novolac Epoxy Floor Coating 10-12.5 gallons

 IV. INSTALLATION

A. Product #12 Epoxy Primer - www.epoxy.com/12.aspx

1. Mixing

a. Stir each component prior to mixing.

b. Mix two (2) parts by volume of Part A (Resin) with one (1) part by volume of Part B (Hardener) for three minutes with a low speed electric drill mixing paddle.

c. If thinning is desired, add no more than one pint of xylene or MEK per gallon of epoxy at time of mixing.

d. Do not mix more material than can be applied in 15-20 minutes (less time in hot temperatures). Do not leave mixed material in the pail for longer than 3 minutes or working time will be significantly reduced!

2. Application

a. Pour mixed resin onto the prepared concrete.

b. Spread with either a flat trowel or squeegee, or roller to a coverage of 200 to 275 ft per gallon. If smaller batches are used, this product can be installed with the "dip and roll" method.

c. Back roll with a short nap roller.

d. Allow primer to cure 8-12 hours (at 75 degrees F) prior to topcoating. A fast cure formulation is available to reduce re-coat window to 4-6 hours. If primer is to be allowed to sit for longer than 24 hours, sand primer before topcoating.

B. Product #633 High Build Chemical Resistant Novolac Epoxy Floor Coating Topcoat

1. Mixing Product #633 High Build Chemical Resistant Novolac Epoxy Floor Coating

a. Stir each component prior to mixing.

b. Mix two (2) parts by volume of Part A (Base) with one (1) part by volume of Part B (Hardener) for three minutes with a low speed electric drill mixing paddle. Add optional Epoxy.com Anti-Skid fine at a rate of 8-12 volume ounces per gallon of mixed epoxy and mix until well dispersed (typically 1 minute).

c. Mix only the amount of material that can be immediately poured out.

2. Application

a. Immediately pour mixed material onto floor in strips and spread at a rate of 160- 200 ft  per gallon with a squeegee. If smaller batches are used, this product can be installed with the "dip and roll" method. Alternately you can use the dip and roll method if you make small enough batches.

b. Back roll immediately with a short to medium nap roller. Do not backroll excessively.

3. Allow to cure overnight or a minimum of 12 to 16 hours at 75 degrees F.

4. Apply second coat the same as step 2.

Allow to cure 24 hours for light traffic, 48 hours for heavy traffic.  For very hot tires, and chemical exposure wait 5-7 days for full chemical cure.
