What is Mastic Adhesive?
Mastic adhesive is a very strong bonding agent used in many commercial and industrial settings, but is perhaps most popular for setting tiles and sealing windows, walls, and ceilings in building construction
Mastic is a type of elastic material
It is used to fill expansion joints in concrete structures and building facades.
The use of mastic causes
The seams can be moved due to changes in ambient temperature
They also act as sealants in water structures.
Types of mastic Adhesive
Mastic are available in various chemical bases: polyurethane, polysulfide, bitumen, and silicone.
The choice of one of the types of this product is based on the use of this material.
Other applications of mastic include sealing composite facades, repairing asphalt cracks, sealing prefabricated parts and pipes, sealing dams and power plants – manholes – drinking water tanks – water and sewage canals – irrigation canals. – He pointed around the windows and..
The strongest and most widely used type of mastic is polyurethane.
Polyurethane mastic are designed as a single component based on polyurethane resin
And as a new generation of thermostatic elastomers, they fill expansion joints.
This type of mastic, with high resistance to sunlight and excellent durability, dries quickly and is very suitable for filling any type of expansion joint due to its anti-algae and moss.

Another type of mastic Adhesive (seam fillers) is bitumen-based mastic, which is offered in two types: hot and cold. The temperature and verticality or horizontality of the desired seam are among the features that should be considered when choosing this type of mastic.
An important point in hot bitumen mastic is the application of heat temperature, which, if the temperature is too high, the mastic will burn. For this purpose, special tools should be used in their implementation.
When running the substrate, the mastic must be free of any contamination. And when using this product, the curing of this material must be completely completed.
