Cementitious grouts for the building and construction industry
Bostik cementitious grouts are examples of how formulated products offer specific qualities to the construction industry.
Cement has a natural tendency to shrink during curing. There are two common forms of shrinkage:
- Early age shrinkage (also called plastic shrinkage) is predominantly due to water evaporating from the matrix.
- Post hardening shrinkage (also called drying shrinkage) is a result of ongoing chemical reactions and hardening.
Class A grouts: (also referred to as General Purpose) are non-shrink during the plastic state.
Class C grouts: (also known as Performance Grouts) are shrinkage compensated (non-shrink) during both the plastic and post hardened state.
Construction grouts: Smart innovations
Applying the right floor primer can greatly improve adhesion of self-levelling underlay to subfloors resulting in a more secure and durable installation. Primers are materials used as a preparatory coating to enhance adhesion of overlaying compounds. They regulate absorption rate of porous substrates and improve adhesion to non-porous materials. Various impervious substrates are becoming a norm. Uses of appropriate primers are necessary to ensure good bonding to these substrates. Failure to do so can lead to de-bonding of coverings.
