Mapesil AC Jasmine (130) Silicone

Product Information

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.

Finishing: When the mix loses its plasticity and becomes opaque, which usually takes place after 15-30 minutes, clean off the excess Ultracolor Plus with a hard, damp sponge (e.g. a MAPEI sponge), working in a diagonal direction to the joints. Rinse the sponge frequently, using two different containers of water: one to remove the excess mix from the sponge, and the other, containing clean water, to rinse the sponge. This operation may also be carried out with a machine with a sponge belt or rotating disc. When the mix is partially set, after 50-60 minutes, a damp Scotch-Brite® sponge or an abrasive felt disc may be passed over the joints to even out the surface. Sealing joints in wall and floor coverings of ceramic and cement, provided they are not subject to heavy abrasion. 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. 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.

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 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. 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 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. 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. 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. Do not use Mapei Mapesil LM for sealing doors subject to intense traffic – (use Mapeflex PU45, Mapeflex PU20 or Mapeflex PU21).

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. 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 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.

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. 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.

Where Mapei Mapesil AC is to be applied in areas of continuous immersion, i.e. inside a swimming pool tank, the joints must be primed using Mapei Primer FD.

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. 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 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. the joint is sized so that the estimated maximum extension is not greater than 25% of the initial width (calculated at +20°C); 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: Excellent durability. Seals remain unchanged even after many years exposure to climatic extremes, industrial pollution, sudden temperature changes and immersion in water; Sealing joints between sinks or sanitary ware and ceramic tiles in kitchens, bathrooms and showers with colours coordinated with the grouts.
