Excellent durability. Seals remain unchanged even after many years exposure to climatic extremes, industrial pollution, sudden temperature changes and immersion in water; Expansion and movement joints on walls and floors must never be filled with Mapei Ultracolor Plus. Use a suitable flexible sealant from the MAPEI range. 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. Do not use Mapei Mapesil LM for sealing doors subject to intense traffic – (use Mapeflex PU45, Mapeflex PU20 or Mapeflex PU21).

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. After the final cleaning operation, if the surface still has traces of Mapei Ultracolor Plus due to incorrect application, it may be cleaned down with an acidic cleaner (e.g. Keranet), by following the relevant instructions, at least 24 hours after grouting the joints. Only use Keranet on surfaces which are resistant to acid, and never use it on marble or limestone material. 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. 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

Under certain conditions Mapei Mapesil LM Silicone may have a water-repellent effect along the edges of joints. This effect is only noticeable when surfaces are wet and is invisible when the same surfaces are dry. This phenomenon, however, has no effect on the product’s performance characteristics. Do not use Mapei Primer FD when sealing stone or marble. 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: 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. 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.

the joint is sized so that the estimated maximum extension is not greater than 25% of the initial width (calculated at +20°C); 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 Mapei coloured grout ranges. Make sure your tiling project’s joints and seals stand up to everyday wear and tear with Mapesil, an acetic-crosslinking silicone sealant from the world’s leading manufacturer of tiling grout, adhesives and sealing products, Mapei.

Mapei Ultracolor Plus is available in 2kg and 5kg bags, in the following colours: Please note, only some colours are available in 2kg bags. Mapei Mapesil LM does not emit unpleasant odours, and comes in the form of a thixotropic paste. It is easy to apply on vertical and horizontal surfaces and cures at room temperature through the humidity present in the air to form a flexible sealant. Seals made using Mapei Mapesil LM are extremely stable over time, even when exposed to inclement weather, industrial environments, temperature variations or water. The product remains flexible over a temperature range of between -40°C and +150°C. Mapei Ultracolor Plus is suitable for grouting walls and floors in areas that are subject to intense traffic, such as shopping centres, airports, restaurants and other public spaces. It is also suitable for residential use in all areas, such as facades, balconies, terraces and swimming pools.For sealing surfaces sensitive to acids such as lime stone, use a neutral silicone sealant (e.g. Mapesil LM).

For sealing floor joints subject to heavy traffic, use a polyurethane (e.g. Mapeflex PU 45 FT) or epoxy-polyurethane (e.g. Mapeflex PU20) sealant. Mapei Mapesil LM Silicone delays the formation of surface mould. Mapei Mapesil LM generally offers good resistance to chemical agents. However, because of the wide range of products and service conditions, if in doubt carry out preliminary tests beforehand. The resistance of Mapei Mapesil AC to chemical agents is generally excellent; however, due to the numerous products and working conditions to which Mapei Mapesil AC can be applied, it is always advisable to do a sample test in cases of doubt. 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.

Thanks to the low modulus of elasticity of Mapei Mapesil LM Silicone, it is suitable for sealing internal and external fillet and expansion joints, including those subject to high levels of movement when in service, between: Pre-fabricated panels, window/door fittings and wall surrounds, pipe-work and vertical walls, similar and/or different types of coating materials. It is also suitable for sealing joints in doors with limited pedestrian traffic. 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. 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
