Boost Liquid Fortifier #025B

YES this does make your foam bulletproof!! OK almost. If I did not know better I would swear my pond and waterfall were made with real rock not foam!! It does what it's name says it Boosts whatever product you add it to. Does this stuff come in a gallon??

Boost, when used in conjunction with All Purpose Foam Coat both indoor and outdoor helps make application smoother and controllable. I use their products including their hot wire foam sculpting tools to make dioramas for educational venues. Great products, you should try them!

Excellent product! Excellent customer service!

This product truly makes the surface of your projects as hard as stone---if you add Boost Liquid Fortifier to your foam coating project, make sure you have it just as you want it before it dries! Thanks HWFF!
