Coverage:
Each 65 lb. bag as described under “APPLICATION” will cover approximately 175-200 sq. ft. (rolled) or 250-350 sq. ft. (sprayed).
Coverage will vary depending on porosity and condition of substrate.

Application & Use:
BONDING CHARACTERISTICS
Scratch Kote affords new pool plaster to bond in 2 additional ways:
1. Mechanically: due to its rough textured surface the Scratch Kote will hold new plaster in place (ie: wall surfaces in particular) until that material takes its set. In this case, the Scratch Kote is mimicking gunnite in appearance and function.
2. Chemically: It is generally accepted that cement based coatings are not fully cured until 30 days after placement. If pool plaster is applied over the Scratch Kote within 30 days of its application, the 2 “uncured” cements (Scratch Kote and Pool Plaster) will bond together to form one unit.
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, acid etch or waterblast with a turbo nozzle or sand injection attachment (3,500 psi minimum). If acid etching, must neutralized and power wash with spinner tip. Make sure to remove all rust, algae, copper sulfate, soft flaky plaster, paint and other foreign matter.
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.
APPLICATION:
MULTICOAT SCRATCH KOTE 2000 is furnished in 65 lb. bags and field mixed with potable (clean) water in the approximate amount of 13⁄4-2 gallons per bag, preferably with a special MULTICOAT Mixing Paddle. (More water may be needed depending upon ambient temperature).
Mix vigorously to disperse all lumps and to thoroughly wet all particles. Suggest 1-1½ minutes after all dry material added. Use margin trowel to clear vessel walls. For best results let Scratch Kote stand in bucket for 3-5 minutes then add a small amount of water to rebreak material. This will give the material additional pot life.
Check for consistency by applying to a prepared vertical pool wall with hopper gun, pressure sprayer or ¾”-1¼” nap roller. Applied material should peak not slump.
If too thick small clumps will come away with roller. Add small amount of water, remix and retest. If material slumps add solids, remix and retest. Dampen pool substrate with water before application.
Apply with ¾”-1¼” 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 OR INDOOR APPLICATIONS – 48 to 72 HOURS IS IDEAL.
