Can foam caulk bond ceramic tiles?

Foam caulkThe full name is polyurethane foam caulking agent ( PU FOAM), also known as Foam glue, foaming agent, is a good construction adhesive that can be used for sealing and filling , the role of sound insulation and noise reduction. So, can foam caulk bond tiles?

Foam caulk is not recommended for bonding tiles,The reasons are as follows:

1. Foam filling Sealing agentprinciple, when the material is sprayed from the aerosol can, The foamy polyurethane material will expand rapidly and solidify with air or moisture in the matrix in contact to form foam;

2、Foam caulkIt has the advantages of pre-foaming, high expansion, small shrinkage, etc., and the foam has good strength and high adhesion. After curing, the foam has the functions of filling, bonding, sealing, It has various effects such as heat insulation and sound absorption. It is an environmentally friendly, energy-saving and easy-to-use building material, can be used for sealing and plugging, filling in gaps Seams, fixed bonding, thermal insulation and sound insulation, especially suitable for sealing, plugging and waterproofing between plastic steel or aluminum alloy doors, windows and walls;

3、Here we knowfoam caulking agent The bigger advantage is its sealing and caulking, which is not very local. Strong adhesion to use for tiling .

The correct materials for tiling are as follows:

1、Standard proportion of cement mortar (i.e. pure cement mortar) for laying;

2、Use tile adhesive and tile back glue for construction and laying;

3、Lay dry-hanging fixings on the wall;

Note: Use strictly prohibitedFoam grout for laying ceramic tiles, Because it is not sticky enough, it is more suitable for sealing and blocking to prevent the tiles from falling off after paving and accidentally injuring people, so be careful.
