How to Apply Tropical 508 Mastic
Surface Preparation
Before applying, make sure the surface is clean, dry, and free from debris or rust.
If temperatures are cold, it is recommended to store the product at room temperature 24 hours prior to application.
Application Method
Apply Tropical 508 mastic using a trowel, putty knife, or gloved hand.
Spread a uniform coat at a thickness of 1/8” to 1/4”, extending 2”–4” beyond the repair area.
Feather the edges to create a seamless, watertight finish.
For larger cracks or holes, embed glass fabric reinforcement before applying a second coat.
Thus, you ensure better strength and a longer-lasting repair.
