Wall, facade, and floor joints help to reduce stress and extend the life of your building’s structure. With the help of an expansion joint sealant, your building envelope can expand or contract without breaking apart or cracking.

The function of the joint and the amount of stress it will experience during use determine the type of substance that should be used to seal expansion or movement joints.

The materials the building is composed of, the finish you want, and any building codes you need to follow should all be taken into account when selecting a solution to seal an expansion joint. In addition, extrinsic elements such as humidity, UV exposure, and environmental pressures need to be taken into account. When combined, these factors may have an impact on the sealed joint’s durability and stickiness.

You must first comprehend the factors to be taken into account when sealing an expansion joint in order to determine which sealant is appropriate for you.

The largest obstacle is the varied movement coefficients of the different materials used to make the joint. For instance, the rates at which gypsum, concrete, and aluminium expand and contract vary. In addition to having a good adhesion on various substrates, the sealant should allow the components it joins to move to varying degrees.

Similar to this, expansion joints in flooring must be strong enough to support heavy foot traffic as well as continuous weight and movement without losing their functionality.Choose the best PU sealant for vertical and horizontal movement joints in Dubai from Mapei at best rate and quality.
