How can I prevent seepage in tile joints?

As tiles tend to move due to physical movements and thermal changes, it is recommended to leave some space between two tiles while fixing them. These joints are filled to prevent seepage of water and accumulation of dirt. Traditionally, white cement was used to fill joints. However, this causes problems, such as cracks in joints, water seepage in bathrooms and colour fading.

Roff Rainbow Tile Mate (RTM) is a ready-to-use, non-shrinking tile joint filler that can be used for ceramic and vitrified tiles in internal and external walls and floors. It is a blend of white cement, special polymers and pigments, and has good UV and water resistance properties. Available in a range of attractive shades to match the décor, Roff Rainbow Tile Mate (RTM) is polymer-modified to provide flexibility, in order to accommodate physical and thermal movements. It also has high compressive strength.

How can I remove stains from tiles?

Conventionally stubborn stains are cleaned with acid, which often spoils the finish of the tiles by reducing their gloss due to the effects of etching.

Roff Cera Clean is a modified cleaner that is perfect to clean ceramic and vitrified tiles. It has an adequate concentration of acid, with detergent properties. This ensures that the stains are removed, without harming the tiles.

How can I prevent yellow stains on marble?

When marble slabs are fixed without sealing the side in contact with the cement or a cement-based adhesive, they absorb water from the cement due to their highly porous nature. This water then rises through the marble’s capillaries. When this water reacts with the naturally present minerals in the marble, it causes stains that are usually yellow in colour.

Roff Stoneguard Solvent-based (SB) is a penetrating sealer, known for its deep penetration and compatibility with cement. It is formulated using the Silane Technology, which makes it completely water resistant and compatible with cement. Also, it does not create any barrier between the
marble and cement-based adhesive, and the staining of marble is prevented effectively. It can be used for the sealing of the back of stones as well as cement-based tile joint filler.

How can I protect the stone’s surface from damage and stains?

Stones are naturally porous and absorb spills and stains quite easily. Conventionally, olive oil, wax and resin were used to protect the surface of stones. But these products were not effective-enough. Modern techniques that use sealers (Silane-based, acrylic -ased) offer good resistance to all problems, apart from stain resistance.

Roff Stoneguard Water-based (WB) is formulated using the Fluorochemical Technology to provide oil and stain resistance, along with water resistance. The product provides adequate penetration that does not only overcome problems, such as salt attack, picture framing, freeze thaw spalling (due to water resistance), but also stain resistance, as its surface tension value is lower than that of oil.

Roff Stoneguard Water-based (WB) also maintains the natural look of stones and allows them to breathe, ensuring durability. It can be used on marble, granite and sandstone in internal and external areas.

How can I protect my wall tiles from cracks?

Tiles usually expand and contract due to the changes in ambient temperatures. However, cement is rigid and not flexible-enough to accommodate thermal movements and other physical changes.

Roff New Construction Tile Adhesive (NCA) is a polymer-modified cementitious tile adhesive. It can be used in the fixing of ceramic and highly porous tiles in the kitchen areas. It is a blend of cement, graded sand and advanced polymers. The added polymers allow the product to accommodate movements due to thermal and physical changes, hence protecting tiles from cracks. The final bonding strength of Roff New Construction Tile Adhesive (NCA) is higher than cement.

How can I protect tile joints from catching fungus?

Fungus is normally seen on tile joints, as ordinary cement or polymerised cement-based grouts are not resistant to water, high temperature and/or chemicals. Neither do they offer a smooth and glossy finish.

Roff Rainbow Tile Mate (RTM) Epoxy is a three-component epoxy tile grout. It does not absorb water, thus preventing fungal growth. It is bacteria-resistant, too. While cement-based grout can provide temperature resistance of up to 60° Celsius only, epoxy grout can provide resistance of up to 100° Celsius. Roff Rainbow Tile Mate (RTM) Epoxy also provides excellent resistance to most acids. Thus, it can be used in all critical areas, such as swimming pools, ponds, hospitals, labs, chemical plants, etc.

How can I ensure that the tile joints last for several years?

Regular polymer-modified joint fillers or normal cement cannot withstand high abrasion. This damages the joints.

Roff Rainbow Tile Mate (RTM) Wide is a polymer-modified sanded cementitious tile joint filler that can be used in high traffic areas. It is coarser than normal grout or cement and gives a high value of compressive strength. Thus, it can withstand high abrasion in outdoor areas and be used in joints wider than 5 mm.

While filling joints, it is recommended that Roff Rainbow Tile Mate (RTM) Additive be used instead of water. Roff Rainbow Tile Mate (RTM) Wide Additive is a latex-based liquid, with high solid content, which when mixed with Roff Rainbow Tile Mate (RTM) or Roff Rainbow Tile Mate (RTM)
Wide enhances flexibility, colour fastness, water resistance and abrasion resistance in critical areas, as it is formulated to offer more flexibility and reduce water absorption. It can be used in areas, such as swimming pools, bathrooms, kitchens, high traffic areas, etc. in internal and external wall and floors.

How can I avoid the breaking of tiles during renovation work?

Conventionally, during renovation, old tiles are broken prior to fixing new tiles. The overall procedure takes up a lot of time. In addition, it is noisy, creates dust, and leaves debris, which is difficult to dispose. The breaking of tiles may also damage the structure.

Roff Non Skid Adhesive (NSA) is a polymer-modified cementitious tile adhesive used for hassle-free tile-on-tile application on internal and external areas on walls and floors. Formulated with special polymers to give bonding to tile-on-tile applications, Roff Non Skid Adhesive (NSA) is a blend of cement, graded sand and polymers. Since the process of breaking the tiles is eliminated, the fixing procedure does not involve dust, noise or debris. Additionally, the tiled floor can be used within 24 hours.

How can I fix heavy stones or tiles, even with thin bed fixing?

Usually, when heavy stones or tiles are fixed with cement, a minimum bed thickness of 20mm is required. This creates an extra load on the structure. Also, due to its shrinkage and rigid nature, it cannot accommodate thermal and physical movements.

Roff Stone Tile Adhesive (STA) is a polymer-modified cementitious tile adhesive that provides enhanced strengthening, even with thin bed fixing. With its blend of cement, graded sand and heavy duty polymers, the product can withstand more load per metre square, so that the same stones or tiles can be fixed with a bed thickness of as much as 6mm, with a zero plumb substrate.

How can I fix tiles on ceilings easily?

Using cement for fixing tiles in critical areas, such as ceilings, is a tedious operation. This is because cement does not give adhesion on concrete without hacking. Also, an additional support of mechanical clamps is required, along with maintaining support, until the cement sets.

Fevitite Vertifix, a two-component epoxy adhesive, outperforms cement. It is formulated to provide ultimate strength and can take extreme load under gravity. As an epoxy, it can adhere to smooth surfaces and be used for fixing tiles or stones on concrete.

Unlike cement, Fevitite Vertifix facilitates quick-setting of tiles in as less as 15 minutes. This makes this product the ideal solution for fixing of tiles and stones in various critical areas.

How can I fix glass tiles easily?

Glass mosaic tiles, being made of glass material, are 100% non-porous and prevent cement from giving adequate adhesion to them, which leads to de-bonding.

Roff Glass Tile Adhesive (GTA) is a polymer-modified white cementitious adhesive. It is a blend of white cement, graded sand and special polymers, which gives good adhesion to the glass material.

Also, as the product is pure white in colour, it helps maintain the original beauty of glass mosaic. Roff Glass Tile Adhesive (GTA) can be used to fix glass mosaic tiles and white marble on internal as well as external walls, floor areas and swimming pools.

How can I prevent the de-bonding of tiles from wood?

Usually, epoxy material is used for fixing tile-on-wood. This involves spreading the epoxy, then sprinkling sand and allowing it to set for 12 hours before fixing the tiles. However, epoxy is non-flexible and causes de-bonding over a period of time.

Roff Ply Master is a polyvinyl alcohol-based (PVA) liquid additive. It is a quick and hassle-free solution, which when mixed with Roff Non Skid Adhesive (NSA) — a cement-based tile adhesive — provides a flexible bond and also prevents moisture from penetrating into the wooden surface. Roff Ply Master can be used to fix tiles and stones on internal or external ply, as well as gypsum or cement fiber board.

How can I prevent the de-bonding of marble?

Conventionally-used cement suffers from shrinkage. Also, it cannot bond well with the smooth surface of marble.

Roff Glass Tile Adhesive (GTA) is a polymer-modified white cementitious adhesive that provides improved bonding to marble. It is a blend of white cement, graded sand and specially-formulated polymers that gives good adhesion to marble. Also, since it is available in pure white colour, it can
