Safety Precautions:
Always wear eye protection, gloves and proper work clothes when using Loctite TITEFOAM Big Gaps after use. Cured foam is difficult to remove
from skin, clothing and other substrates. May discolor skin. When transporting odd cans by passenger car leave the container wrapped in a cloth
in the trunk, never in the passenger compartment.
Surface Preparation:
Ensure all surfaces are clean and free from dirt, dust, oil and other contaminants likely to impair adhesion. Surfaces can be moist but not frosted
or iced. Cover surfaces not intended to be foamed. To ensure full and even curing of the foam on porous substrates (i.e. brickwork, concrete),
moisturize surfaces with water spray before application.
