#216 GUNZITE Primer: Primer for New and Other Rough Surfaces
This epoxy primer should be used as a filler for newly gunited surfaces. It is also an excellent material to fill holes, depressions and pits in all interior concrete or plaster pools. It will "smooth up" a rough surface and provide a smooth base for the succeeding coat of ZERON or coats of POXOLON.
APPLICATION DIRECTIONS
Catalyst is under the lid in a separate container for use in 5 gallon cans for GUNZITE Primer. It is in a separate container when it is to be mixed with either quarts or gallons. IMPORTANT! Be certain to remove all the catalyst from the can when mixing with the base. STIR VERY THOROUGHLY. We strongly recommend the use of an electric mixer to achieve proper mixing of any two-component material. Wait according to the induction schedule. All GUNZITE containers are short filled to allow room for the addition of the catalyst. When the catalyst is added, it will fill the container.
For best results, the entire surface to be coated must be acid cleaned before applying GUNZITE Primer. This removes loose grit and unsound surface materials. After acid washing, the surface should be washed with tri-sodium phosphate in order to neutralize and remove all traces of acid. Surface should then be hosed off.
On new concrete, gunite, plaster or Marcite, and block surfaces, GUNZITE Primer is "daubed" on the surface with a stiff bristled masonry brush or delivered to the surface. It is then spread out or "floated" with a rubber trowel, rubber sponge or by rolling with a short 1/4" nap roller. It also may be applied with a masonry brush. When the GUNZITE tends to run out of holes it should be "bodied up" by adding our #955 aggregate until the required consistency is developed. A fine white silica sand or marble dust may be substituted for our aggregate. This provides a smooth base for the application of the top coat of POXOLON and ZERON. Whenever a "textured" surface is acceptable, it is not necessary to use the GUNZITE Primer, as its main function is to create a smooth base for the coating that would be applied.
If there is a cement base masonry paint on the concrete surface, it should all be removed before painting,, as it is a very questionable base. Muriatic acid will usually remove cement paint. Use our Bulletin #141 for acid cleaning. After removal, paint as bare or new concrete.
When a builder switches from plastering pools to a ZERON coating, it may take two or three pools to acquire the technique to produce a smooth surface for the application of ZERON. During this period, all rough spots can be eliminated with the application of GUNZITE Primer.
Clean application equipment with #1109 Solvent.

MAXIMUM RECOATING TIME OF GUNZITE WITH POXOLON OR ZERON:
48 hours
POT LIFE: POXOLON, and GUNZITE Primer
Approx. 4 hours @ 85ú F
Approx. 6 hours @ 75ú F
Approx. 8 hours @ 60ú F
POXOPRIME II

|
NOTE! |
|
Above 85ú F, use immediately after mixing thoroughly with catalyst. Do not mix 5 gallon containers unless you can use within 30 to 40 minutes. The smaller the quantity mixed at one time, the longer the "pot life." ALWAYS STORE AND MIX IN A COOL PLACE. |

NOTE! |
|
Pot life and working time can be increased by thinning 5% to 10% with #1109 Epoxy Solvent. Highly recommended when surface temperatures exceed 90ú F. Add water with Poxoprime II. |
