Application of Ethafoam™ strips

Surface cleaning

Before applying the new sealant, a thorough cleaning of the surfaces is conducted, followed by the application of a primer. This preparation is essential to remove any traces of dirt or dust that could compromise the adhesion of the sealant.

Application of a new high-quality sealant

Finally, we apply a premium quality sealant, strictly adhering to the manufacturers' technical specifications. Careful smoothing of the caulking joints is carried out to ensure flawless waterproofing.
