Another essential step in the application process is using a scraper or a similar tool to press the tape onto the surface. After initially applying the tape to the frame, any excess material will be subsequently fixed to the surrounding wall.
This step is necessary to create a solid connection between the frame and masonry, thus forming a continuous layer of protection against infiltration. In each corner, it is important to form a loop of at least 4 cm for proper sealing.
Use a scraper or another suitable tool to apply even pressure across the entire surface of the tape. This operation will improve adhesion and ensure perfect contact between the tape and the support surface. For insulating window sills or edge profiles, it is ideal to use a pre-compressed, expandable sealing tape (similar to foam).
This type of tape adapts perfectly to narrow spaces, expanding after application to provide complete and durable sealing.
Following the 3 recommendations presented will guarantee you efficient and long-lasting sealing, protecting you from energy loss, unwanted infiltration, and external noise.
