Introduction of grout sealant

Ensure that the depth of the sealant is not greater than the width. If the gap between the two substrates is large, it is necessary to insert moldings to improve the performance of the sealant. Use a suitable tool to smooth the sealant to make the surface more beautiful; at the same time, the sealant is pressed into the joint surface to help eliminate air pockets or voids in the adhesive layer.

The area of the substrate in contact with the sealant must be kept clean, dry, and free from dust, dirt, rust, grease, and other contaminants. Non-porous substrates must be cleaned with a clean white lint-free cotton cloth and solvent. Before the residual solvent evaporates, wipe it off with a clean dry cloth as soon as possible. Before sizing, cut the nozzle of the rubber tube first, install the glue nozzle, and cut the nozzle to the required size. The sealant can be coated in dots or layers, and needs to be exposed to moisture in the air to cure.

Acidic system: Acidic silicone sealant has excellent adhesion to the surface of common substrates in bathrooms or kitchens such as glass or ceramics. Neutral system: When sealing metal, plastic or concrete substrates, a neutral sealant must be used. Neutral silicone sealant is particularly suitable for non-corrosive sealing of connection joints and expansion joints.
