#214 POXOPRIME II

POXOPRIME II is a two part epoxy primer designed for use on wet or dry concrete or plaster pool surfaces. When used according to these instructions, POXOPRIME II seals these bare surfaces and provides a perfect base for chemical acceptance of either POXOLON (2 coats) or ZERON (1 coat) epoxy finish.

POXOPRIME II is required on bare surfaces to seal in acid salts, hydrates, and other undesirable elements which normally migrate to the surface. These elements (when not sealed off) could result in poor adhesion and performance of the pool coatings. Do not use POXOPRIME II over other coating or on metal or fiberglass, only on bare concrete or plaster

SURFACE PREPARATION

In order for POXOPRIME II to successfully penetrate and seal the surface to be coated, the bare surface must be sound and freed of contaminants such as oils and mineral deposits. The cleaning process consists of three steps.

First, to remove oily residue, scrub the surface with tri-sodium phosphate (our #910 Pool Washing Compound) and water. Mix 8 ounces of tri-sodium phosphate to each gallon of warm water. Use liberally and pay careful attention to the water line and drain where oils tend to accumulate. Scrub in 10 foot sections, hosing off with water after each section.

Next, the surface should be acid etched with a 10 to 20 per cent solution of muriatic acid. Acid etching "burns" away contaminants unaffected by the tri-sodium phosphate. Acid etching also opens millions of microscopic pores in the surface which allow POXOPRIME II to adequately penetrate. (Our bulletin #141 gives complete acid etching information). The person participating in acid etching should wear rubber boots, rubber gloves and goggles.

The third step is to again scrub the surface with tri-sodium phosphate solution to neutralize the acid. Upon completion, rinse with water.

MIXING DIRECTIONS

One can contains the base portion and is to be thoroughly mixed with the catalyst at the rate of one part catalyst to three parts POXOPRIME II. Be sure to remove all the catalyst from its separate container. It is best to mix using an electric drill equipped with a mixing attachment. Mix until all traces of the catalyst disappear plus three additional minutes. After the catalyst has been thoroughly mixed, POXOPRIME II may be applied. No induction time is necessary. For expediency, you may want to mix two or three gallons at a time in a clean plastic bucket.

APPLICATION

POXOPRIME II is best applied by rolling with a 1/2 " nap roller. A brush may also be used for trimming; however, do not brush out too thin. Always apply liberally. It is very important to completely seal the surface. On saturated surfaces POXOPRIME II should be applied without thinning. If necessary, (i.e., hot day, dry or very smooth plaster) thin with one pint of water for each gallon of POXOPRIME II.

POXOPRIME II works equally well when surfaces are wet. However, standing water, or puddles, should be allowed to dissipate before application. If the surface is exceedingly wet, POXOPRIME II may appear to "dilute." Therefore, be sure to totally cover the surface. POXOPRIME II, however, will not block hydrostatic pressure such as underground steams. See "PHYSICAL DATA" for further information.
