|
The MULTICOTE SLATEX BELOW GRADE Waterproofing System is a multilayer seamless protective coating
which combines an elastomeric waterproof membrane (MULASTICOAT) with a Synthetic Resin modified cementitious coating.
The SLATEX BELOW GRADE SYSTEM can be applied to most surfaces such as concrete block, poured in place concrete, slumpstone, polyfoam sheathing, etc.
Advantages
- Superior Waterproofing
- Easy to Apply - No Special Safety Apparatus Required
- Cost Effective - Minimal Down Time
- Highly Resistant to Fungus/Mildew
- Superior Bonding
- High Impact and Abrasion Resistance
- Superior Freeze - Thaw Resistance
- Waterbase - Environmentally Safe to Use and Apply
Specifications
I Description and Scope
The MULTICOTE SLATEX BELOW GRADE Waterproofing System is a multilayer seamless coating consisting
of a waterproofing membrane protected by an overcoat of a Synthetic resin modified cementitious material.
It can be applied to walls or foundations constructed of concrete block, poured in place concrete, slumpstone,
polyfoam sheathing, etc.
The scope of this specification is to describe the materials and installation procedure for the SLATEX BELOW
GRADE Waterproofing System.

III SURFACE PREPARATION
1. All surfaces must be structurally sound and free of grease, oil, paint, dirt, dust, sealers, laitence, concrete
curing compounds and other foreign materials which may prevent proper bonding of MULASTICOAT.
2. Cracks must be repaired and all holes, voids, bee hives, etc. must be filled with suitable mortar or grout.
They should be allowed to cure and scraped even with surface prior to application of MULASTICOAT.
3. Surface should be dry to touch prior to MULASTICOAT application.
IV Application
1. MULASTICOAT
A. Apply first coat of MULASTICOAT firmly with a 3/4" to 1 1/4" nap roller. Cover entire surface
area, including footing, extending to a minimum 6" above grade line. Allow to dry a minimum
of 2 hours prior to second coat application.
B. Apply second coat (crisscrossed) with airless sprayer or roller cover. Be sure all pin-holes, voids,
etc. are completely covered. Allow to dry a minimum of 24 hours.
NOTE: Coverage, two(2) coats. 40-50 sq. ft. per gallon.
2. SCRATCH KOTE 2000 Protective Coating
A. Clean MULASTICOAT Surface with damp sponge.
B. Apply finish coat of SCRATCH KOTE 2000 with 1 1/4" roller cover. SCRATCH KOTE 2000
vigorously feild mixed with potable (clean) water to thoroughly disperse solids in approximate
amount of 1 1/4 to 1 1/2 gals per 65 lb. bag. Use MULASTICOAT special mixing paddle, and margin
trowel to clear vessel walls. Adjust consistency so applied material does not slump or stick to
roller.
C. One hour after application is complete, check to make sure MULASTICOAT is completely
covered (no blue should show). Allow 24 hours before back filling. DRAINAGE SYSTEM
SHOULD BE INSTALLED BEFORE BACK FILLING.
3. PRECAUTIONS
A. Entire substrate and waterproofing covering should be in accordance with all applicable
building codes.
B. New concretes should be aged a minimum of 10 to 20 days after pouring and at least 2 days after
form removal before ccommencing applications.
NOTE: When liquid form releases are needed, use only WATERBASE products.
IV Warranty
Materials are guaranteed with respect to uniformity and quality within manufacturers' specifications. Seller makes no other warranty, expressed or implied, regarding the use of its products. Since use of the product is beyond the Seller's control, the Buyer assumes all risks of use. Seller's sole obligation shall be to replace materials if found to be defective. Seller shall not be liable for any damages, injury, loss, direct or consequential, resulting from use of its products.
