Mapesil AC Jasmine (130) Silicone

Product Information

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. 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.

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 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. Sealing joints between sinks or sanitary ware and ceramic tiles in kitchens, bathrooms and showers with colours coordinated with the Mapei coloured grout ranges. 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.Mapei Ultracolor Plus creates water repellent grout joints that have excellent colour uniformity. All colours are resistant to UV rays and atmospheric agents. All Mapei Ultracolor Plus grout colours are also available in a matching silicone – Mapesil AC Silicone. If using this grout with moisture sensitive natural stone tiles, a low modulus silicone is advised – 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 cord 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. 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 in wall and floor coverings of ceramic and cement, provided they are not subject to heavy abrasion. Forming a perfectly elastic gasket between different elements in building, mechanical engineering, ship-building, automobile manufacturing, etc. 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. 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.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. 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. 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. 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. the joint is sized so that the estimated maximum extension is not greater than 25% of the initial width (calculated at +20°C);

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.

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. 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 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. Final cleaning of the powdery film of Mapei Ultracolor Plus from the surface may be carried out with a clean, dry cloth. 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 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. Do not use Mapei Mapesil LM for sealing doors subject to intense traffic – (use Mapeflex PU45, Mapeflex PU20 or Mapeflex PU21).
