HEAVY DUTY FLOOR TOPPING
This application brochure is intended to assist the contractor in successfully installing the following products manufactured by ChemProof Polymer Flooring.

PERMACOAT 3000, 4000, 5000
PERMACOAT 3000 CT
PERMACOAT 2000

GENERAL DESCRIPTION
The PERMACOAT systems are 100% solids epoxy and 100% solids modified epoxy floor coatings. They can be utilized as a glaze coat for the PERMATEC high build floors, or as a two coat flooring or containment system (16-60 mils). When applied as a two coat floor or containment systems, a silica broadcast is required between coats.

PERMACOAT systems can be installed over most sound floors, including old or new concrete, steel and wood.

All of the PERMACOAT systems are applied in the same manner, only the "A" to "B" (Resin to Hardener) weights and ratios are different. For a complete ratio listing refer to the "Weights and Ratios" bulletin.

PACKAGING
Each kit size is made up of the following components:
Part A - Resin
Part B - Hardener

Gallon Kit	Component	Package
1	A	1 - 1 gal. pail
	B	1 - 1 qt. can or 1/2 gal. jug
3	A	1 - 3 1/2 gal. pail
	B	1 - 1 gal. or 2 1/2 gal. jug

Silica is not normally supplied with PERMACOAT products due to the shipping costs. A cleaned, dried, rounded silica is recommended. Mesh sizes of 30-75 are most commonly used, with the size being determined by the final texture desired.

Note: Do not use mesh sizes over 75 unless a sample areas has been performed. Silica over 75 mesh may cause uneven finishes.

SURFACE PREPARATION
New Concrete - The concrete should be well cured for a minimum of twenty-eight (28) days, per ACI 308-81, (R-1986), clean, dust free and free of all contaminants. Mechanical methods such as sandblasting, or shot blasting should be employed to remove the weak layer of surface laitance. A minimum tensile strength of 200 psi is required of the prepared surface. Acid etching with muriatic acid is acceptable but less desirable. Care must be taken to completely remove all residual acid prior to the application of any coating product.

CHECKING FOR CONTAMINATES IN NEW AND EXISTING CONCRETES
Prior to commencing the surface preparation in new or existing concrete, all surface contaminates such as chemical residue, waxes, oils, grease, paints, or sealers must be removed.

Paints or sealers can be removed by mechanical means, such as shot or sand blasting. Mechanical methods may not be adequate for the removal of chemical residue, waxes, oils and grease.

If greases and oils are present, degreasing preparations must proceed the final concrete prep. After scrubbing the concrete with a degreasing solution, a 1 to 1 mix of muriatic acid and water should be poured onto the substrate. If a vigorous and uniform bubbling appears, the degreasing operation was a success and normal preparation procedures may begin. If the bubbling does not appear, the degreasing step must be repeated.

COVERAGE
The table below gives finished floor thicknesses after the silica broadcast (40 mesh) and the final topcoat. Only the thickness of the first coat is varied. 

1st Coat Coverage	1st Coat Thickness	Finish Floor Thickness
(Sq. Ft.)	(mils)	(mils)
200	8	25-35
150	12	30-40
100	16	50-60

Note: The second coat, or topcoat for the systems listed above will totally encapsulate the exposed silica at a coverage rate of approx. 100 sq. ft. per gallon.

MIXER REQUIREMENTS

A jiffler mixer on a low speed (400-600 rpm) drill has proven to be most effective in mixing PERMACOAT products. When mixing 3 gallon kits, the larger jiffler mixer should be used.

MIXING
Prior to application, the PERMACOAT material (Resin & Hardener) and the substrate should be a minimum of 65 degrees F.

Do not begin mixing until material is ready for use.

1. Premix the Part "A" for 30 seconds to assure even pigment distribution.

2. Pour Part "A" (Resin) and Part "B" (Hardener) into the mixing bucket, mix for approximately 1 1/2 - 3 minutes.

3. Immediately remove the mixed material and distribute it onto the work areas. The prompt placement of the material will insure adequate time for the application.

Do not mix more than 3 gallons at one time.

APPLICATION
Note: Before applying PERMACOAT products, the substrate (i.e. Concrete or a PERMATEC floor) should be visibly dry.

PERMACOAT AS A GLAZE COAT (over PERMATEC Heavy Duty System)
After mixing immediately pour the PERMACOAT material onto the floor. Using a rubber squeegee (or steel trowel), pull the material tightly and evenly over the desired area (Typically 90-110 sq. ft. per gallon). Follow behind the squeegee with a quality mohair or wool nap roller to distribute the resin evenly and encapsulate all the exposed silica. 

PERMACOAT AS A FLOOR OR CONTAINMENT SYSTEM
After mixing immediately pour the PERMACOAT material onto the floor. Using a rubber squeegee (or steel trowel), pull the material tightly and evenly over the desired area (Typically 100-200 sq. ft. per gallon). Follow behind the squeegee with a quality mohair or wool nap roller to distribute the resin evenly.

A silica broadcast should be made approx. 10-20 minutes after the area has been back rolled.

The excess silica can be removed as soon as the PERMACOAT will support foot traffic (Approx. 4 to 8 hours @ 70 degrees F). Following the removal of all excess silica, the second coat of PERMACOAT is applied with squeegees and rollers as set out above. There is no silica broadcast into the final coat. The final coat should be applied within 48 hours of the first to insure a proper bond.

BROADCASTING
Silica broadcasting should not begin until the application process (i.e. back rolling) has progressed for approx. 10-20 minutes. Silica can be broadcast by hand and in larger applications can be blown with a 3-bag pressure pot. Broadcast until there is an even excess layer of silica and no "shiny" spots.

Note: Do not broadcast into the working edge of the material. This will make it very difficult to tie the next batch of material in properly. Also, allow the silica to float down onto the resin surface as opposed to "sidearming" the silica. This can cause the resin surface to be pushed into ridges.

CLEAN UP
All mixing and application equipment should be cleaned immediately after use. If this is done, soap and water, or biodegradable cleaners can be used. If the material has begun to set, more aggressive solvents may be necessary. Before using solvents, refer to their respective MSDS for handling considerations.

STORAGE AND SHELF LIFE
The PERMACOAT products should be stored at 50-90 degrees F and out of sunlight. Containers should remain unopened until ready for use. If stored as set out above, a minimum shelf life of 1 year can be realized.

WHERE PERMACOAT PRODUCTS SHOULD NOT BE INSTALLED
PERMACOAT products should not be applied over substrates:

• subject to hydrostatic pressure

• unsound structures

• contaminated substrates which cannot be cleaned

• at temperatures below 65 degrees F (Consult ChemProof Polymers).

SAFETY
PERMACOAT flooring systems contain blended Epoxies as the resin and blended Amines as the hardener. Protective clothing and gloves are recommended to prevent sensitization to these materials. In case of ingestion or eye contact, contact a physician immediately. MSDS are available for this product upon request.
