Mapei Mapesil is a pure acetic silicone sealant, highly elastic and resistant to mould. These coloured silicones match all the colours in the Mapei Ultracolor grout collection available at Tile Fix Direct. Mapei Mapesil AC Silicone is a solvent-free, acetic crosslinking, mildew-resistant silicone sealant with low modulus of elasticity.
Mapei Mapesil AC Silicone is ideal for ealing expansion joints of ± 25% expansion of the initial size. It is also great for forming elastic gaskets between different elements in building, mechanical engineering, ship-building, and automobile manufacturing. It is sold in 310ml tubes from Tile Fix Direct and forms a skin in just 10 minutes.
Some application examples of Mapei Mapesil AC Silicone:
- Sealing joints in wall and floor coverings of ceramic and cement, provided they are not subject to heavy abrasion.
- Sealing joints between sinks or sanitary ware and ceramic tiles in kitchens, bathrooms and showers with colours coordinated with the grouts.
- Sealing expansion joints in swimming pools.
- Assembling compositions of glass tiles and artistic stained glass windows.
- Sealing glazing of door and window frames.
- Sealing air ducts, water pipes.
- Sealing portholes, windows, glazed frames.
- Sealing tanks, service pipes and boilers.
- Sealing materials of different thermal exposure coefficient.
- Adhesive and sealant for general use.
What is the use of Mapesil AC?
Mapesil AC silicone is ideal for sealing joints in wall and floor coverings of ceramic and cement, (provided they are not subject to heavy abrasion), joints between sinks or sanitary ware, and ceramic tiles in kitchens, bathrooms and showers.
How long does it take for Mapei silicone sealant to dry?
24 hours
Protect the installation area from light foot traffic and water exposure for at least 24 hours at 73°F (23°C). Protect from heavy traffic for 3 to 5 days.
What is the difference between silicone and non silicone caulk?
While caulk is long-lasting on solid, unmoving surfaces, silicone sealant's flexibility means it lasts longer in areas with higher moisture. Using silicone sealant in a bathroom for sealing cracks in the tub and shower will create a more durable seal without needing to frequently re-apply.
Application Procedure:
Preparing and calculating joints size: All the surfaces to receive Mapei Mapesil AC Silicone must be dry, solid and free from dust and loose particles, oils, grease, wax, old paint and rust. In order that the seal can carry out its function, provision must be made for it to elongate and compress freely.
During application it is therefore necessary that:
- it adheres only to the side of the walls of the joint and not to the base of the joint;
- the joint is sized so that the estimated maximum extension is not greater than 25% of the initial width (calculated at +20°C);
- when the width of the joint is 10 mm, the thickness must be equal to the width; for widths between 11 and 20 mm the thickness must always be equal to 10 mm; for widths greater than the thickness must be equal to half the width.
To control the depth of the joint and to prevent Mapei Mapesil AC Silicone from adhering to the base, the bottom of the joint should be filled with a sized Mapefoam, a polyethylene cord.
Application of Mapei Primer FD: Where the use of Primer FD is necessary, it must be applied with a small brush onto the appropriate areas of the joints and left to dry for several minutes to allow the solvent to evaporate. Then apply Mapei Mapesil AC Silicone.
Mapei Mapesil AC Silicone is packed in cartridges of 310 ml; to use, cut the cartridge above the end of the thread and screw on the nozzle, which should be cut at 45° to produce a hole corresponding to the size of the joint. Insert the cartridge into the gun and extrude the sealant. The surface of Mapei Mapesil AC Silicone must be finished off with a damp tool, preferably moistened with soapy water, before a superficial film has formed.
