100% Solids Mortar Epoxy System

HOW TO PREPARE SURFACE FOR Floor Poxy COATINGS 100% Solids Mortar Epoxy System?

Inspection

• Surface must be structurally sound, dry and free of oil, grease, curing agents, dirt, dust or other foreign material that may prevent proper adhesion. Surface must be porous and profiled (See Preparation section.) The concrete should be at least 2500 psi and feel like 30-grit sandpaper. The concrete should be porous and be able to absorb water. A minimum of 28 days cured is required on all concrete. Relative humidity in the concrete floor slab should be below 80% (per ASTM F-2170).
• Before starting flooring work, test existing concrete slab to make sure there is no efflorescence, moisture and/or high levels of alkalinity.
• Calcium chloride tests should be conducted to determine if the concrete is sufficiently dry for an epoxy flooring installation in accordance with the latest edition of ASTM F 1869, Standard Test Method for Measuring Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride.
• Failing to adhere to these strict guidelines can result in product delamination, discoloration, blistering, or all together failure of the coating system. Testing is the responsibility of the applicator. Life Paint bears no responsibility for failures due to any of the above conditions.

Surface Preparation

Cleaning

Clean surface entirely with TSP and rinse completely with water several times. Remove mildew or algae using 50/50 blend of household bleach and water. (Do not allow bleach to come into contact with acid). Read bleach instructions and warnings carefully before using. Rinse thoroughly and allow to completely dry.

Crack Preparation

Use a concrete diamond blade to cut out all cracks and joints to 1/4 inch width and 1/4 inch depth. Clean joints thoroughly and remove all concrete dust and debris.

Etching

• Clean surface entirely with TSP and rinse completely with water several times. Remove mildew or algae using 50/50 blend of household bleach and water. (Do not allow bleach to come into contact with acid). Read bleach instructions and warnings carefully before using. Rinse thoroughly. The surface must be porous enough to allow the product to soak in. Surface should feel like 30 grit sandpaper.
• Prepare surface by either shotblasting, grinding, Liquid Grind ^TM (approved liquid etch) or, if a previous coating is currently installed, sanding. Prepare concrete profile equal to CSP 2-3 as specified by ICRI (International Concrete Repair Institute. When using a mechanical method, be sure not to be too aggressive leaving behind grind marks or grinding it to a smooth surface.

HOW TO INSTALL Floor Poxy COATINGS 100% Solids Mortar Epoxy System?

Crack Fill/Patching Installation

Using LD7200 Crack Patch, mix paste by equal volume 1:1. LD7200 is mixed thoroughly when combined product is completely gray. Apply to crack, joint, or spalled area using a putty knife or trowel, completely filling the space, scraping off extra LD7200 to leave a uniform, level finish. When dry, sand or grind smooth if overfilled. Surface will be ready to prime in 4-6 hours.

Primer (Optional)

In a clean and dry bucket, thoroughly mix two parts A with one part B of LD 12 Series epoxy together by volume. Combine using an agitator, jiffy mixer or stir stick. Mix for at least 2 minutes or until completely combined, scraping the sides and bottom of mixing bucket. Only prepare the amount you can use in 25 minutes or less (larger batches than 1.5 gallons may short pot life.) The primer is ready to be applied by brush, roller, or squeegee. If using a squeegee, be sure to back roll for uniform coverage. Coverage should be approximately 200-300 sq. ft. per gallon.

Tack Coat

Premix each component separately of the LD33-96. Mix 2 parts A Resin with 1 part B Hardener, by volume, into a clean container. Mix thoroughly with a low speed (400-600 rpm) drill motor/jiffy mixer for 3-4 minutes. Make sure to scrape the sides and bottom of the container during mixing.

LD33-96 Clear should be applied using a ¼”-3/8” non-shedding nap roller, brush, or squeegee. Apply at approximately 250 sq. ft. per gallon (6-7 mils), evenly, with no puddles. Wait until primer is tacky (minimum 3 hours), before applying the Troweled Mortar. If Troweled Mortar is not going to be applied while LD33-96 Clear is tacky, broadcast silica sand into coating lightly but uniformly and allow curing overnight.

Intermediate Coat

Premix each component separately. Mix 2 parts A Resin (1 gallon) with 1 part B Hardener (1/2 gallon), by volume, into a clean container. Mix thoroughly with a low speed (400-600 rpm) drill motor/jiffy mixer for 3-4 minutes. Make sure to scrape the sides and bottom of the container during mixing.

Place mixed Warm Cure Mortar Epoxy into a KOL Mixal or Kenrich EAM4-60T5 bucket mixer. Slowly add 72 lbs of Graded Silica or “Monterey” Sand. Mix until aggregate is uniformly wet. Immediately dump mortar onto substrate and squeegee or skreet at 3/16”. Coverage should be approximately 50 square feet per kit at 3/16”. Coverage will vary depending on depth of system.

Compact and smooth the mixed material using a hand or power trowel. When power troweling, take precaution not to burnish the color. Allow to cure overnight.

Fill Coat

Premix each component separately of the LD33 Series. Mix 2 parts A Resin with 1 part B Hardener, by volume, into a clean container. Mix thoroughly with a low speed (400-600 rpm) drill motor/jiffy mixer for 3-4 minutes. or until completely combined, scraping the sides and bottom of mixing bucket. Make sure to scrape the sides and bottom of the container during mixing. Apply LD33 Series using a steel trowel or red rubber squeegee and back roll using a 1/4” nap roller at a spread rate of 100 sq. ft. per gallon (16 mils).

Allow to cure overnight. Apply additional fill coats if needed at a rate of 200-250 sq. ft. per gallon (6-8 mils).

Top Coat

In a clean and dry bucket, thoroughly mix two parts A with one part B of LD 33 Series epoxy together by volume. Mix thoroughly with a low speed (400-600 rpm) drill motor/jiffy mixer for 3-4 minutes or until completely combined, scraping the sides and bottom of mixing bucket. Only prepare the amount you can use in 25 minutes or less (larger batches than 1.5 gallons may short pot life.). The top coat is ready to be applied by brush, roller, or squeegee. If using a squeegee, be sure to back roll for uniform coverage. Coverage should be approximately 200-300 sq. ft. per gallon.

MAINTENANCE + HEALTH ADVISORIES FOR LIFE SPECIALTY COATINGS 100% Solids Mortar Epoxy System?

Maintenance

Floors should be inspected during use for inconsequential damage and wear. Damage areas should be remediated as soon as possible to prevent further damage to the area(s). To repair, remove any loose coating and refer to this specification; repeat process in affected area.

Clean daily using a dry soft bristled broom, dry mop, or wet mop with a floor/tile cleaner, to retain the epoxy looking new.

Health, Protection and Safety

Refer to individual product container labels, individual product technical data sheets, and SDS for health, protection, and safety precautions.
