Poly foam caulk savers are used behind caulks to fill wide cracks and save on caulk.
Non-absorbent, closed-cell polyethylene pre-caulking material helps repel moisture. Use before caulking to fill gaps and openings larger than 1/2" x 1/2". Prevents 3-point bonding.
Use to partially fill deep cracks or joints before applying sealant. 3/4" closed cell. To be applied to 1/2 in. width joints and below.
Use to insert into a joint to control sealant depth, to create a backstop, allow proper sealant tooling, allow proper sealant wetting of the joint surfaces and use as a temporary seal.
Use before applying caulk on new construction or remodeling. For walls, floors, trim, sidewalks, windows and doors. Closed-cell.
Fills gaps and openings to prevent drafts. Provides a sound surface for caulking projects.
