installation of Rafs for exterior
The plot of ceramic tiles is determined by the position of the plots. The slabs rest on these located in the four corners of the tile, at
least, may be placed in other provisions in formats upper to 45 x 45 cm or rectangular. Consumption per m2 depends on the format
of the tiles outside STE and resistance is needed.
The plots are fi xed to the support using polyurethane adhesive. Similarly, and to avoid bending the tiles, they adhere to the plot.
This system is adapted to the needs of each customer, so that from data of the project, butech adapts the outside STE to the
particularities of each project.
This provision ensures good stability to the system and allows greater fl exibility in the design of the ceramic drawing, and can
design placements with locked joint. The plots are to be placed on a solid support and a maximum gradient of 2%. For covers, the
support must be covered by a waterproof sheet, while outdoors, where no waterproofi ng system is required, the plots may rest
directly on the support, if it is solid and stable, with the fl ap fi tted directed toward the sink.
This type of pavement over-raised avoids the need for cement mortar screeds for subsequent placement of cement-based tile
adhesive. This system avoids the disadvantages of terraces that may arise from the traditional placement of direct adhesion.
The problems arising from variations in temperature, structural settlements or poor performance of the fl ooring are eliminated.
Also allows obtaining additional benefi ts as a convenient accessibility at any time, allowing correct possible defects in the existing
waterproofi ng and easy start work without the need for highly specialized, reduced noise transmission and thermal protection of
the room beneath the system due to the creation of an air chamber that is in constant ventilation and the joints between tile and
tile 4 mm left open for drainage of water.
