Grouting compounds (grouting) they are used to fill gaps between ceramic tiles, stone ones, glass etc..

Types of grouting compounds:

• Ordinary cement mortars – Dry cement mixtures, modifying additives and fillers. The texture and allowable width of the joint depend on the type of fillers used. The use of mineral flour in the mortar allows it to be applied to narrow joints with a smooth surface. On average- or coarse sand which is in the composition of the mortar allows for a wider joint with a rougher surface.

• Elasticized cement mortars – Cement mortars, refined with polymers increasing the flexibility of the joint. These mortars contain fine-grained mineral or synthetic fillers that ensure a lower porosity of the grout. They set quickly and provide a joint that reduces the deformation of the tiles under the influence of temperature. The joint is frost-resistant and waterproof – mortars can also be used outdoors. They can be used on floors with underfloor heating. A special type of flexible cement mortars are mortars for pointing to marble floor coverings.

• Epoxy compounds – They are offered in the form of two-component preparations, in which one component is a chemically resistant epoxy resin with fillers and the other is a hardener. The hardened joint has high mechanical strength and is tight and resistant to all chemicals used at home

• Silicone masses, silicone-acrylic and acrylic – They are available in the form of one-component ready masses applied from special packages called cartridges. They are waterproof and resistant to the formation of fungi and mold. They give a flexible grout, which is used to fill gaps in wall corners, at the connection point between the wall and the floor and any expansion joints.

In places exposed to mechanical damage, masses are used that give a hard surface of the grout in places, where there are large temperature differences and high humidity, flexible joints must be used. In utility rooms and garages, tight and chemically resistant joints should be used. The tiles must have the possibility of deformation., therefore outside – due to temperature fluctuations, the joints must be wider (min. 4 mm). The width of the grout also depends on the size of the tiles - large tiles require wider grouts. On the other hand, by grouting smaller tiles inside rooms, you can make a carpet with narrow joints.
