Mapesil AC Jasmine (130) Silicone

Product Information

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. Sealing joints between sinks or sanitary ware and ceramic tiles in kitchens, bathrooms and showers with colours coordinated with the grouts. 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. 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. 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.

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. 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. Sealing joints in wall and floor coverings of ceramic and cement, provided they are not subject to heavy abrasion. 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. 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 cordMapei 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. 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. 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: 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. 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.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 does not contain Portland cement and must not be mixed with gypsum or other hydraulic binders; never add water to the mix once it has started to set.

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. For sealing surfaces sensitive to acids such as lime stone, use a neutral silicone sealant (e.g. Mapesil LM).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. Forming a perfectly elastic gasket between different elements in building, mechanical engineering, ship-building, automobile manufacturing, etc. Do not use Mapei Mapesil LM for sealing doors subject to intense traffic – (use Mapeflex PU45, Mapeflex PU20 or Mapeflex PU21). 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.
