Final cleaning of the powdery film of Mapei Ultracolor Plus from the surface may be carried out with a clean, dry cloth.

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. 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. 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.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. 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. When Mapei Mapesil LM is exposed to the air, the surrounding humidity sets off the cure reaction and the sealant becomes flexible. The surrounding temperature only has a small impact on the cure rate of Mapei Mapesil LM, while the level of humidity in the surrounding air has the most influence. We highly recommend that the product is never applied if the temperature is below 0°C.

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. Forming a perfectly elastic gasket between different elements in building, mechanical engineering, ship-building, automobile manufacturing, etc. 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 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. 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. Mapei Ultracolor Plus creates water repellent grout joints that have excellent colour uniformity. All colours are resistant to UV rays and atmospheric agents.
