The video introduces the process of covering existing wall tiles in a bathroom without demolition. The first step involves thoroughly cleaning the tiles with a degreasing detergent to remove any ingrained grime and prepare the surface for priming. Subsequently, the entire floor, fixtures, and any surfaces not intended for treatment are meticulously covered and taped off to prevent accidental spills and facilitate a clean application of materials. Special attention is given to hard-to-reach areas, requiring specific tools for thorough coverage.
Once the preparation is complete, the surface is primed using Mapei Eco Prim Grip, a primer specifically chosen for non-absorbent surfaces like tiles. The primer is allowed to dry for at least 24 hours. After drying, the first coat of cementitious resin, Mapei Keraflex white, is applied. The video skips the detailed application of these initial layers, referring to a previous, less descriptive video demonstrating a similar process. The video emphasizes the importance of this method for those interested in renovating their bathroom without extensive demolition.
After the second coat of Keraflex white has dried, approximately 48 hours later, all imperfections and crests are sanded and removed to create a smooth surface. All masking tapes are removed, and the area is thoroughly cleaned and vacuumed to eliminate dust. New masking is applied for the final coat. This last coat of Keraflex white is mixed with Mapei Isolastic, creating a more elastic and durable mortar. This mixture ensures the surface becomes completely non-absorbent, making it suitable even for shower areas.
After the final layer of resin mixed with Isolastic is applied, all tapes are immediately removed to allow for optimal drying. The surface needs at least 48 hours to cure and achieve its desired performance. Following this, any micro-irregularities are carefully cleaned using a spatula and a diamond sponge, making sure to remove all dust. The final step involves applying two consecutive coats of a professional acrylic fixative, applied pure and in crossed brushstrokes, starting from top to bottom, with 24 hours of drying time between coats, to provide ultimate protection and a sealed finish.
