III. SURFACE PREPARATION

1. Check and completely remove all hollows and loose areas with picks and hammers.

2. Chip out minimum 2 inches below tile line and around all water inlets, return lines and light fixtures.

3. Sandblast or waterblast with sand injector (3,500 psi minimum) to remove all rust, algae, copper sulfate, soft flaky plaster, paint and other foreign materials.

4. Recheck for hollows, loose and flaky areas, Soft flaky areas must be removed before SCRATCH KOTE 2000 is applied.

5. Wash thoroughly with waterblaster and dry all areas to touch before proceeding.

IV. APPLICATION

1. MULTICOAT SCRATCH KOTE 2000 is furnished in 65 lb. bags and field mixed with potable (clean) water in the approximate amount of 1 ¼ - 1 ½ gallons per bag, preferably with a special MULTICOAT Mixing Paddle.

Mix vigorously to disperse all lumps and to thoroughly wet all particles. Suggest 1 - 1 ½ minutes after all dry material added. Use margin trowel to clear vessel walls.

Check for consistency by applying to a prepared vertical pool wall with 1 ¼" nap roller. Applied material should not peak or slump. If too thick small clumps will come away with roller. Add small amount of water, remix and retest.

Apply with 1 ¼" nap roller or spray to entire prepared surface. ALLOW TO CURE FOR A MINIMUM OF 24 HOURS BEFORE APPLYING POOL PLASTER-LONGER IN COOL WEATHER - 48 to 72 HOURS IS IDEAL.

NOTE: Indoor pools must have a minimum 72 hour cure time before applying pool plaster.

V. WARNING

Do not apply when substrate temperature is below 50oF, above 100oF, when ambient temperature is below 50oF and falling, above 100oF and rising, or if precipitation is expected within a 24 hour period.
