FOR THIN JOINTS 2÷6 mm
FOR EXTERNAL AND INTERNAL USE

USE

ATLAS GROUT is designed for filling 2 ÷6 mm wide joints in wall and floor ceramic tiles (glazed tiles, terracotta, gres tiles), natural stone and stone agglomerate tiles, concrete tiles and china mosaics. It is used for grouting tiles fixed on stable wall wood-based panels and plasterboards, and in wall or floor heating systems. It can be used in dry, damp and wet rooms, on terraces, balconies and façades. ATLAS GROUT can be used for filling joints in new tiles as well as in supplementing or replacing joints in renovated tiles. ATLAS GROUT with ATLAS SILTON S and ATLAS EDGE TRIMS are a set of products used for professional finish of various tiles. It is suitable for indoor and outdoor use.

PROPERTIES

ATLAS GROUT for thin joints is a dry compound of top-quality cement binder, specially selected aggregates, fillers, dyes and modifying additives. The compound has low absorptivity, high flexibility, resistance and adhesion. It has very good operating parameters, in particular, it is crack, scratch and abrasion resistant and adheres strongly to tiles. Owing to its operating parameters, it is very convenient, plastic and easy to use. It enables quick and easy joint filling and does not scratch tile surface. A wide range of 40 colours (including white) makes it easier to match the compound with the tile colour. ATLAS GROUT compound is frost- and water-resistant.

SUBSTRATE PREPARATION

Before grouting, carefully remove dust and any dirt from joints. A joint between tiles should be of even depth, therefore remove excess of the adhesive when tiles are pressed towards the surface. You can begin grouting only after the adhesive on which the tiles had been placed has set; not earlier, however, than after 24 hours. If ATLAS MIG adhesive is used, tile grouting can begin after 4 hours. Just before grouting, clean tile surface with a moist sponge and slightly wet the joints (in particular if grouting begins after complete drying of the adhesive or in case of renovations – in places from which old joints have been removed). There may be discolouration of excessively absorptive tiles (e.g. marble). Therefore, try grouting on a small section of a joint before proper tile grouting.

MORTAR PREPARATION

In order to prepare the grout, pour dry compound into a container with suitable amount of water (in proportion: 0.30÷0.33 l of water for 1 kg of dry mortar) and mix until homogenous, manually or mechanically. The grout is ready to use after ca. 5 minutes and after remixing. It maintains its properties for ca. 2 hours.

APPLICATION

The grout is placed deep and tightly into joints using a felt or spatula made of rubber. After initial grout setting, clean the surface. Clean using a wet hard sponge with bigger pores or a float with sponge. Excessive soaking of joint surface with water may result in washing out of pigments and washing out of the fresh mortar. At the final stage of work, it is recommended to use an appropriate small piece of cloth or a hard sponge with small pores. Do not clean in dry conditions due to the risk of a colour change resulting from rubbing in the dry mortar into the wet joint. In order to maintain optimum grout setting conditions, keep fresh joints slightly wet for the first few days e.g. by sprinkling or rinsing the surface with clean water. The actual colour of the joint is set when the joint has dried completely - after about 2 - 3 days. Note: due to the possibility of appearance of small differences in colour, it is recommended to use a grout of the same date and batch number in a given place. Avoid excessive drying. Begin grouting tiles outdoors so that the setting mortar is not exposed to precipitation, low temperatures (below +5°C) and high air humidity, at least for three days. Non-observance of the aforementioned recommendations and application of inappropriate amount of water for grout preparation may result in deterioration of grout parameters and discolouration. Differences in joint depth, various types of china and tile washing too early may result in uneven colour shade on grout surface. In joints located in particular parts of tiles (internal and external corners, expansion joints), use appropriate finishing strips e.g. ATLAS EDGE TRIM or fill them in with permanently elastic materials e.g. ATLAS SILTON S silicone. To reduce grout absorptivity and increase grout resistance to dirt, it is recommended to use (when it is completely dry i.e. after ca. 2 weeks) ATLAS DELFIN protective agent. The information comprises basic instructions of product application and does not relieve users of responsibility for work in accordance with good construction practice and OHS regulations.

CONSUMPTION

Consumption depends on joint width and depth, and what type of tiles is applied. For example, 1 kg of dry grout compound is sufficient for ca. 2 m2 of 15x15 cm ceramic tiles, with joints of 3 mm in width and 4 mm in depth.

TOOLS

A drill with a mixer, spatula or rubber float, sponge and sponge float. Wash the tools with clean water directly after use. Clean the remainder of the set mortar, that is difficult to remove, with ATLAS SZOP.
