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

PERMATEC 3000, 4000, 5000
PERMATEC 3000 CT
PERMATEC 2000

GENERAL DESCRIPTION
ChemProof's heavy duty flooring products are supplied in 20, 100, and 1000 square foot units. These coverages are based on a standard 1/4 inch thickness.

Applied at 1/4 inches these materials will withstand the most severe mechanical and chemical abuses. However 1/8 inches can be applied in less severe environments with minor modifications to the following procedure.

All of the PERMATEC 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 AND COVERAGE
Each kit size is made up of the following components:
Part A - Resin
Part B - Hardener
Part C - Mix Silica
Part D - Broadcast Silica

20	A	1 - 1 gal. pail
	B	1 - 1 qt. can or 1/2 gal. jug
	C	25 lbs - loose
	D	18 lbs. - bag
Note: Parts A, C and D are contained within a 5 gallon pail. Part B is packages separately.

Note: Prior to application, 1000 Sq. Ft. units of part "A" should be broken down into 10 - 100 Sq. Ft. units.

SURFACE PREPARATION
New Concrete - The concrete should be well cured for a minimum of 10 (ten) days, per ACI 308-81, (R-1986), clean, dust free and free of all contaminants. Mechanical methods such as sandblasting, scarifying, 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 flooring product.

Existing Concrete - Concrete must be structurally sound and free of all contaminants. Weak or contaminated concrete must be removed until sound concrete is realized. Old coatings, toppings, waxes, oils, etc. must be removed prior to the application.

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.

RECOMMENDED SILICA (PT C) AMOUNTS
The following recommendations describe the amount of Part C that can be used for various application procedures. The amounts and coverage are based on 100 sq. ft. units.

Operation	Thickness (inches)	Part C (lbs.)
Hand Troweling	1/4	125
	1/8	100
Screeding	1/4	100
	1/8	80
Patching	1/2	140
Note: For more severe patching requirements refer to the PermaGrout E technical data sheet.

For sloped concrete, 140 lbs. of Part C is recommended by an immediate broadcast of Part D to prevent flowing.

Field adjustments of silica are often necessary to adjust to temperature and surface conditions.

MIXER REQUIREMENTS
A 5-gallon bucket mixer having a side and bottom scraping action is recommended for mixing 20 sq. ft. kits.

A 2 1/2-3 cubic foot mortar mixer is recommended for mixing 100 sq. ft. kits. Standard cement mixers may not sufficiently mix PERMATEC products, and are not recommended.

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

Do not begin mixing until material is ready for use.

1. Pour Part "A" (Resin) and Part "B" (Hardener) into the mixer and mix for approximately 1 1/2 minutes.

2. Add Part "C" (Silica) slowly to the "A" - "B" mix. Continue mixing only long enough to wet evenly and disperse the Part "C" (1 to 3 minutes), and stop the mixer.

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.

In order to maintain a clean mixer from batch to batch, the Resin (Part A) and a portion of the Silica (Part C) should be added to the mixer and agitated long enough to clean the blades. Do not leave the mixer running, however, unless you are ready for the next batch. Continual mixing of the material between batches can introduce excessive amounts of air into the mix, resulting in bubbling on the floor.

Add the Hardener (Part B) only when the batch is ready to be applied. Mix for approx. 1 1/2 minutes, then add the remainder of the silica and mix for another 90 seconds. Pour immediately onto the floor.

APPLICATION
A self-leveling tendency will be noticed after the material has been poured on the surface to be coated, however some assistance is required in order to achieve the specified thickness. Conventional hand-troweling and screed raking are the two recommended methods of application. Screed raking is generally preferred because of the uniformity in thickness that can be achieved.

After the material has been leveled with a screed rake or trowel, you can backroll the surface with a nap or spike roller to even out the surface and remove screed marks.

SCREED RAKE SETTINGS AND USE
In order to achieve a 1/4 inch thickness the screed rake must be set between 1/8 and 3/16 inches. If a ruler is not available on site, 1/8 = 1 nickel and 1 dime; 3/16 = 2 quarters and 1 dime.

During screeding, the rake must be held perpendicular to the floor. If the rake is tilted away from you and pulled, the topping will be applied thinner. If the rake is leaned toward you and pulled, the topping will be thicker than desired.

After raking and before broadcasting, the rake marks can be removed with a porcupine roller or trowel. It is most effective to roll perpendicular to the rake marks.

The screed rake settings set out above will serve as a starting point. Proper coverage must be verified by marking off the floor and checking to make sure a 100 S.F. kit is covering 100 S.F. The screed rake can then be adjusted accordingly. 

BROADCAST
Part D (Silica) broadcasting should not begin until the application process (i.e. troweling or screeding, back rolling) has progressed for approx. 10-20 minutes.

Part D 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 Part D. This can cause the resin surface to be pushed into ridges.

After the material has set (usually 4-8 hours at 75 degrees F) the excess silica can be removed and disposed of.

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 heavy duty toppings 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 PERMATEC PRODUCTS SHOULD NOT BE INSTALLED
PERMATEC 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
PERMATEC 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.
