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 Final cleaning of the powdery film of Mapei Ultracolor Plus from the surface may be carried out with a clean, dry cloth. 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. Mapei Ultracolor Plus creates water repellent grout joints that have excellent colour uniformity. All colours are resistant to UV rays and atmospheric agents.

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 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 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.

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

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 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. 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. 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 Tile Grout is made up of a blend of special hydraulic binders, graded aggregates, special polymers, water repellent admixtures, organic molecules and pigments.
