- Features
- The W60LA's adhesive qualities permit the firm adhesion of Styrofoam insulation. A seal around the tire wires for bricks, etc.
- W60LA is designed to supplant the normally used parging coat (a thin coat of mortar) to smooth the exposed exterior surfaces of the concrete masonry units (concrete block.) W60LA is applied in two coats using a brush and/or roller. Apply second coat only after first coat is dry.
- W60LA eliminates the mortar parging coat plus the waiting time for the parging coat to set-up and dry before installing the vapor retarder/adhesive to adhere the insulation.
- W60LA will adhere without priming to most concrete masonry units and most concretes.
- W60LA is formulated in a winter grade for cold weather ease of application below temperatures which preclude the installation of mortar parging coat.
Exceptions: All surtfaces which require a primer to stabilize and wet the substrate surfaces including:
- Latex concrete
- Most concrete cure agents and some form board release agents
- Concrete block which has an excessive granular surface
Applications & Uses
- Applications
- Compatible Substrates & Surfaces
- Application Method
- Use a brush and/or roller (medium to heave nap).
- Spray application is laborious because atomization of the product is difficult due to the amounts of rubber used in manufacturing. If you use a sprayer, open tip so it applies in a thick stream and spread with a brush and/or roller.
- Apply W60LA at a rate of 30 mils per 100 sq. ft. min per application (3 gallons per 100 sq. ft. or one square) to obtain a film thickness of 1/16 or 60 mils minimum (2 coats).
- To seal tie wires apply around wires with a gloved hand or trowel.
- Embed specified insulation into wet to tacky second co0at of W60LA material.

Safety & Health
- Caution
- Accidental spills or drips during application may be removed by releasing a C02 foam extinguisher to freeze and peel off offending material. Do not use solvents to remove. Solvent will thin the W60LA allowing an even deeper penetration.
- Further staining may be removed by lightly sand-blasting. Cellulose organic fibers, i.e. ground corn husks are recommended. Use a lanolin/solvent type hand cleaner to remove product from skin. Follow by washing with soap and water.
- For tool clean-up prior to storage use ALCM power clean.
