MAPESIL AC is a high quality, mould resistant sealant, which is ideal for internal use but can also be used in external applications. The product comes in a 310ml cartridge & has a range of 42 colours to choose from. Mapei also colour match this product to their Ultracolor plus grout range, creating a seamless transition between grout & silicone lines when used together.
To view the Ultracolor plus range – please click here.
– Mapesil AC should not be used in applications between joints of ceramic tiles & natural stone of light colour externally. Use Mapesil LM, which can be viewed here.
– Should not be used for sealing of surfaces sensitive to acids, such as limestone. Again, use Mapesil LM.
– Do not use on bituminous surfaces or highly plasticized material.
– Mapesil AC’s chemical resistance to agents is typically excellent. However, we advise you to check the technical data sheet or do a small test.
We have a number of tools on our website that would assist with the application of this product. We would recommend using a PC Cox Skeleton Gun to apply & a Bond-it Tooling Kit to aid in providing a professional finish.

CM Stonesil is an elastic single-component silicone sealant for indoor and outdoor use, with up to 50% movement tolerance.
Ultracolor Plus forms a mortar with the following characteristics:
– water-repellent and droplet-effect
– colours resistant to ultra-violet rays and atmospheric agents
– ready for light foot traffic after a short period of time
– After that is shrinkage compensated, therefore free from cracks
Therefore it has optimum resistance to abrasion, compression and flexural strength, even after freeze/thaw cycles, and therefore optimum durability. In addition, it has good resistance to acids with pH > 3.

Dowsil 791 or DC 791 is a low modulus, neutral cure, alkoxy, odourless silicone sealant. It is specifically designed for the weather sealing of building components where high movement is anticipated. Dowsil 791 adheres to a wide range of both porous and non-porous surfaces without the need for priming.
– Excellent tooling and slow skinning properties. Therefore, it is ideal for large scale construction and glazing applications.
– Has excellent adhesion – adheres to most common surfaces. For instance, glass, metals, plastics and wood (painted or unpainted), uPVC and polycarbonate.
– Excellent external weathering properties, therefore, can be guaranteed over many years worth of exposure.
– High viscosity non-slump formula. In other words, it will hold it’s structure & body on even larger joints.
– Resistant to fumed Hydrogen Peroxide and fumed Formaldehyde.

Keracolor Flex is an improved, cementitious grout with water repellent properties and high abrasion resistance.
Keracolor Flex is a blend of specially selected hydraulic binders with fine graded aggregates, polymers, additives and colourants. High-quality hydrophobic additives enhance the grout’s technical performance imparting water repellent properties to the surface. This reduces dirt pickup and increases the grout’s durability and longevity.
When mixed and applied correctly to the joints, the following properties are obtained:
• water repellent surfaces;
• joint widths from 1-6mm
• good compressive & flexural strengths
• good resistance to freeze & thaw cycles
• gently textured surface with a low water absorption
• excellent abrasion resistance
• good resistance to thermal change and vibration
• can be used on heated floors
• for use on tiled finishes over wooden substrates
• resistance to oils, solvents & alkaline cleaning materials
Keracolor Flex can be mixed with Mapei’s Fugolastic to further improve the grout’s performance. This high-quality polymer additive can effectively enhance the characteristics of the grout when used on balconies and facades, which can face harsh weather conditions. This also makes it ideal for leisure pools with wave machines or in external locations. For further information, refer to
the Fugolastic technical datasheet.
Note: when adding Fugolastic, the grout may appear darker than when mixed with water.

Arbosil XL1099 is a non-staining, one part LM, neutral cure, sealant that cures on exposure to moisture vapour, to form an elastic rubber silicone.

Mapesil LM is a low-modulus, solvent-free sealant, formulated for sealing all materials that are sensitive to acids and plasticizing agents, marble, granite, sandstone and quartz. Due to the chemical nature, which deters surface bleeding or the migration of plasticizing agents which would stain the surface.
The characteristics of the product also make it suitable for particularly delicate substrates, such as cellular concrete, brickwork and varnished or enamelled wood.
It is also ideal for contact with absorbent mineral surfaces such as concrete, renders and fibre-cement.
Performs well in treated water typically found in swimming pools.
Mapesil LM is a solvent-free, one-component, neutral-cure silicone sealant which does not emit unpleasant odours, available in the form of a thixotropic paste. The product will remain flexible from a temperature range of between -40°C and +150°C. Mapesil LM delays the formation of surface mould. Mapesil LM 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.
Mapesil LM bonds perfectly to most types of substrate used in the building industry without applying a primer beforehand (glass, ceramic, marble, aluminium, zinc-plated sheet metal, concrete, stainless steel and PVC).
If in doubt, please contact the MAPEI Technical Services Department or carry out preliminary tests beforehand. Mapesil LM is suitable for substrates sensitive to acids, whereas conventional neutral or acid sealants normally provoke changes in colour or staining of the substrate.
For optimum application, use with a PC Cox Easiflow Skeleton Mastic Applicator Gun, and finish with the Bond It Professional 4 Part Sealant Applicator Tool Kit for a smooth neat finish.
