Installation

General Polymers materials shall only be installed by approved contractors. The following information is to be used as a guideline for the installation of the DECORATIVE MOSAIC EPOXY COATING

SYSTEM. Contact the Technical Service Department for assistance prior to application.

Surface Preparation — General

General Polymers systems can be applied to a variety of substrates, if the substrate is properly prepared. Preparation of surfaces other than concrete will depend on the type of substrate, such as wood, concrete block, quarry tile, etc. Should there be any questions regarding a specifi c substrate or condition, please contact the

Technical Service Department prior to starting the project. Refer to

Surface Preparation (Form G-1).

Surface Preparation — Concrete

Concrete surfaces shall be abrasive blasted to remove all surface contaminants and laitance. The prepared concrete shall have a surface profi le depending upon system selected. Refer to Form G-1.

After initial preparation has occurred, inspect the concrete for bug holes, voids, fi ns and other imperfections. Protrusions shall be ground smooth while voids shall be fi lled with a system compatible fi ller. For recommendations, consult the Technical Service Department.

Temperature

Throughout the application process, substrate temperature should be 50ºF – 90ºF. Substrate temperature must be at least 5ºF above the dew point. Applications on concrete substrate should occur while temperature is falling to lessen o� gassing. The material should not be applied in direct sunlight, if possible. Protect material from freezing prior to installation.

Primer Mixing and Application

1. Add 2 parts 3579A (resin) to 1 part 3579B (hardener) by volume.

Mix with low speed drill and Ji� y blade for three minutes and until uni-form. To insure proper system cure and performance, strictly follow mix ratio recommendations.

2. 3579 may be applied via spray, roller or brush. Apply at a spread rate of 200-300 sq. ft. per gallon, evenly, with no puddles. Coverage will vary depending upon porosity of the substrate and surface texture.

3. 3579 application varies upon usage.

NOTE: Epoxy materials may tend to blush at the surface especially in humid environments. After the surface is primed and before installation of each subsequent coat, surface must be examined for blush (a whitish greasy fi lm and/or low gloss). The blush must be completely removed prior to recoating using warm detergent water or through solvent wipe.

Epoxy materials will appear to be cured and dry to touch prior to full chemical cross linking. Allow epoxy to cure for 2-3 days prior to ex-posure to water or other chemicals for best performance.

Base Coat Mixing and Application

1. Premix 3746A (resin) using a low speed drill and Jiff y blade. Mix for one minute and until uniform, exercising caution not to introduce air into the material.

2. Add 2 parts 3746A (resin) to 1 part 3746B (hardener) by volume.

Mix with low speed drill and Ji� y blade for three minutes and until uni-form. To insure proper system cure and performance, strictly follow mix ratio recommendations.

3. Apply 3746 using a squeegee or trowel and back roll with a 1/4” nap roller at a spread rate of 200-300 square feet per gallon making sure of uniform coverage. Take care not to puddle materials and insure even coverage.

4. Allow material to self-level 10-15 minutes. Begin evenly broadcasting

6750/6755 Vinyl Chips into wet resin much the same as grass seed is spread. Vinyl Chips should be broadcast in such a way that the chips falls lightly into resin without causing the resin to move. Continue broadcasting to excess until the fl oor appears completely dry.

5. Allow to cure for 12 hours, sweep o� excess vinyl chips with a sti� bristled broom.

Grout Coat Mixing and Application

1. Premix 3746A (resin) using a low speed drill and Ji� y blade. Mix for one minute and until uniform, exercising caution not to introduce air into the material.

2. Add 2 parts 3746A (resin) to 1 part 3746B (hardener) by volume.

Mix with low speed drill and Ji� y blade for three minutes and until uni-form. To insure proper system cure and performance, strictly follow mix ratio recommendations.

3. Apply 3746 using a squeegee or trowel and back roll with a 1/4” nap roller at a spread rate of 160-250 square feet per gallon making sure of uniform coverage. Take care not to puddle materials and insure even coverage.

4. Allow to cure (Cure times vary depending on environmental condi-tions) before applying seal coat.

Seal Coat Mixing and Application DO NOT PREMIX PART B HARDENER

1. Premix 4686A (resin) using a low speed drill and Ji� y blade. Mix for one minute and until uniform, exercising caution not to introduce air into the material.

2. Add 1part 4686A (resin) to 1 part 4686B (hardener) by volume. Mix with low speed drill and Ji� y blade for three minutes and until uniform.

To insure proper system cure and performance, strictly follow mix ratio recommendations.

3. Apply 4686 using a 1/4” nap roller at a spread rate of 250-400 square feet per gallon, evenly, with no puddles making sure of uniform coverage. Take care not to puddle materials and insure even coverage.

4. Allow to cure 24 hours minimum before opening to light foot traffi c.

5. If a second seal coat is required, lightly sand and wipe clean prior to coating.

Cleanup

Clean up mixing and application equipment immediately after use.

Use toluene or xylene. Observe all fi re and health precautions when handling or storing solvents.

Safety

Refer to the MSDS sheet before use. federal, state, local and particular plant safety guidelines must be followed during the handling and installation and cure of these materials.
