FAQ:

Q: Where would you use expanding foam?

A: Expanding foam can be used in under-bathtub applications. It is not a replacement for a mortar slab in new installs but is a practical solution for improving stability and insulation of an existing tub.

Q: What is non expanding foam?

A: Non-expanding foam, or low-expansion foam, has a number of applications where it outperforms nearly every other material such as insulating small cracks and holes, waterproofing areas of a house or even insulating very large, hard-to-reach locations.

Q: Is foam waterproof?

A: Yes foam can be waterproofed but only rigid foam, flexible foams have a tendency to absorb water and hence can not be waterproofed. 1) cover sprayed foam or foam board with a separation layer of geotextile cloth. 2) lay screed concrete of 25 mm over geotextile cloth. 3) apply EPDM Membrane/ APP Membrane over concrete.

Q: Can spray foam sealants?

A: Spray sealants can be applied using a small, hand-held aerosol canister. Spray sealants are made out of plastic polymers. Spray sealant often comes in the form of foam insulation, which holds in heat very well. A respirator mask should be worn when working with spray sealant.
