Steps Involved in Caulking
Whether you wish to prevent mould build-up or repair an old and worn sealant, Les Entreprises JSDR inc. has you covered. Our effective caulking process comprises the following steps :
Removal of the Old Sealant
The first step involves completely removing the old sealant using a high-powered multipurpose tool. This will facilitate the application of the new sealant and achieve improved airtightness at the end of the process.
Application of Ethafoam™ Backer Rods
This step is necessary when the joints are too large, and the sealant alone is not enough. Applying Ethafoam™ backer rods to the joints will create a suitable base for supporting the new sealant.
The third step involves cleaning all surfaces and applying a primer to ensure that no dirt or dust interferes with the adhesion of the new sealant.
Application of the New Sealant
The fourth step consists in applying a new superior-quality sealant according to the manufacturers' technical specifications and smoothing the joints to improve waterproofing.
