When Boost liquid fortifier is mixed with our Foam Coat it makes it incredibly strong and weatherproof, plus makes it stick to almost anything! Typical proportion for Boost to dry mixture:
Instructions:| Amount of Boost | Amount of Foam Coat |
| 1 Gallon Boost | 50 lbs Foam Coat |
| 2 Quart Boost | 25 lbs Foam Coat |
| 8 oz Boost | 3 lbs Foam Coat |
MIXING: New formula does not require dilution. It’s okay to mix water with Boost, but that will diminish Boost’s strength. Start with 1 part liquid to 3 parts Foam Coat, and thin or thicken as desired. Thinning the Foam Coat with more Boost will not weaken it.
APPLYING: Fill large cracks and holes with pasty mixture. To coat large areas, add more liquid until thin enough to apply with a paint brush. May be applied as thick as 1/4 inch, but multiple coats are stronger. Try texturing surface before coating sets.
SET TIME: Use within 20 minutes. Sets hard in 1-2 hours. Maximum bond and hardness in 24 hours.
CLEAN-UP: Immediately clean tools and brushes with soapy water. Boost cannot be removed once dry.
FINISHING: May be painted or stained.
Suggested Dilutions Boost:Water
It's best to use at 100% for maximum added adhesion and strength, but can be diluted up to 50% with water.
