Cleaning and roughening a surface using a chemical agent prior to coating in order to increase the adhesion.

The liberation of heat energy during a chemical reaction.

Separations between adjoining parts of a concrete slab allowing separate movement of the parts. They are usually filled with an elastomeric type of material. Expansion joints should never be filled with a cementitious underlayment product because any movement of the separate parts may cause the underlayment to break up and be pushed out of the joint. Resilient flooring should not be installed over this type of joint as cracking and buckling may occur.

A material added to a compound to lower cost with minimal degradation of properties.
