Applying the grout: Fill the joints with the Mapei Ultracolor Plus mix using a special MAPEI grout float or rubber squeegee, without leaving any gaps or steps. Remove any excess of Mapei Ultracolor Plus from the surface, by moving the float diagonally to the joints while the mix is still fresh. For sealing surfaces sensitive to acids such as lime stone, use a neutral silicone sealant (e.g. Mapesil LM). When Mapesil LM is constantly immersed in treated water typically found in swimming pools its physical-mechanics may be affected prematurely. Given the wide range of products used to treat water and the actual quantities employed, its suitability over long periods may only be guaranteed following specific laboratory testing. When resistance to acids or, where extreme cleanliness or sterile conditions are required, use a suitable acid-resistant epoxy grout.

Mapei Mapesil LM Silicone Sealant is a neutral, mould-resistant silicone sealant with very low emission level of volatile organic compounds (VOC), for use with natural stone and marble. Sealing joints in wall and floor coverings of ceramic and cement, provided they are not subject to heavy abrasion. 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 Mapei Ultracolor Plus Tile Grout is made up of a blend of special hydraulic binders, graded aggregates, special polymers, water repellent admixtures, organic molecules and pigments.If the cleaning operation is carried out too soon (the mix is still too wet), some of the mix may be removed from the joints. If grouting is carried out in extremely hot, dry or windy weather, we When Mapei Mapesil LM is exposed to the air, the surrounding humidity sets off the cure reaction and the sealant becomes flexible. The surrounding temperature only has a small impact on the cure rate of Mapei Mapesil LM, while the level of humidity in the surrounding air has the most influence. We highly recommend that the product is never applied if the temperature is below 0°C. Mapei Ultracolor Plus creates water repellent grout joints that have excellent colour uniformity. All colours are resistant to UV rays and atmospheric agents. Sealing joints between sinks or sanitary ware and ceramic tiles in kitchens, bathrooms and showers with colours coordinated with the Mapei coloured grout ranges.

Do not use Mapei Mapesil AC Silicone for joints in exterior between ceramic tiles and light-coloured natural stone because dirt could accumulate by the joints. Use Mapei Mapesil LM Silicone.

Final cleaning of the powdery film of Mapei Ultracolor Plus from the surface may be carried out with a clean, dry cloth. Sealing joints between sinks or sanitary ware and ceramic tiles in kitchens, bathrooms and showers with colours coordinated with the grouts. Mapei Ultracolor Plus forms a smooth, compact finished surface with optimum resistance to abrasion, compression and flexural strength, and good resistance to acids with a pH > 3. Floors are ready for light foot traffic after approx. 3 hours. Surfaces grouted with Mapei Ultracolor Plus may be put into service after 24 hours. Basins and swimming pools may be filled up 48 hours after grouting.

Do not apply Mapesil LM Silicone on rubber, heavily-plasticised plastics or bitumen. The oil and plasticising agents in the substrate may migrate to the surface and compromise the bond or penetrate into the sealant leading to a variation in colour and mechanical characteristics. Forming a perfectly elastic gasket between different elements in building, mechanical engineering, ship-building, automobile manufacturing, etc. The use of Mapei Mapesil AC is not recommended on highly plasticised material or on bituminous surfaces because of the release of substances that reduce bonding and penetrate into the sealant, altering the colour and resistance.

Mapei Mapesil LM is particularly suitable for surfaces sensitive to acids on which conventional neutral or acid sealants normally provoke changes in colour or staining of the substrate. Mapei Mapesil AC Silicone is a one-component, acetic crosslinking, solvent-free silicone sealant, available coloured or transparent. It is a thixotropic paste which is easily trowellable both horizontally and vertically. Mapei Mapesil AC Silicone crosslinks following exposure to atmospheric humidity at ambient temperatures, and forms an elastic product with following properties: Mapei Mapesil AC Silicone is a solvent-free, acetic crosslinking, mildew-resistant silicone sealant with low modulus of elasticity, available in 42 colours and transparent, to match the range of Mapei Coloured Grouts. After first having used a bonding enhancer, such as Mapei Primer FD, Mapei Mapesil AC Silicone can also be used on concrete, wood, metal, painted surfaces, plastic and rubber. Preparing the mix: While stirring, pour the Mapei Ultracolor Plus Grout powder into a clean, rust-free container containing 21-23% by weight of clean water. Mix the grout with a low-speed mixer to avoid air entrainment, until a smooth paste is obtained. Let the mix stand for 2-3 minutes, and stir again briefly before use. Use the mix within 20-25 minutes of its preparation. Mapei Ultracolor Plus is available in 2kg and 5kg bags, in the following colours: Please note, only some colours are available in 2kg bags.
