Fixing natural or artificial stone on façades

Thanks to the development of fixing materials and attachment techniques, for several years stone (natural or artificial) has been an attractive option for architects and builders, for use as a decorative, non-supporting coating for façades.


The tiles are adhered directly to the support with adhesive mortar and mechanical anchors. With this system, the stress that can be generated in the façade, is taken directly to the tiles, and this can cause them to work loose.

Using an appropriate anchoring system is essential when working with glued façades, and therefore it is important to use VAT® FLEX RAPID as the fixing material, i.e.: an adhesive mortar with high adherence and flexibility, which helps to prevent the tiles from falling.

Apply directly to concrete elements, or plaster on brickwork.

When applying the coating to mortar plastering, wait one week for each centimetre thickness of the plastering. It is important that the plastering shrinks fully.

Check that the support is strong and stable, and check smoothness with a 2 m ruler to avoid any excessive adhesive mortar thickness.


Set out beforehand to determine the exact position of the slabs.

Spread VAT® FLEX RAPID on to the support with a notched trowel.

Apply the Floating and buttering method (see page 19) when the tile is larger than 900 cm2 and/or weighs more than 40 kg/m2.

Press the tiles to ensure they all form a solid surface, thus avoiding any gaps between the tile and the support.

The arrangement joints between the tiles during fixing must be at least 5 mm. Use BORADA® UNIVERSAL or BORADA® PLUS.

Correctly plan and implement the movement joints (width 8 to 10 mm) and seal with BETOFLEX.


  • Do not apply in wet weather, or at temperatures <5ºC or >30ºC.
  • Do not fix the tiles with spots of cement.
  • You can use VAT® FLEX RAPID on outdoor base plate renders on a brick support, up to a maximum height of 2 m.
  • In specific cases when the render is very heavy or the support is not yet mature, it is important to use PAM® SUPERFLEX COMPACT, an adhesive mortar with high adherence and very high deformability.
  • It is advisable to leave a 5 cm gap between the first façade slab and the floor, to prevent water rising via capiliary action, which could damage the coating materials.
  • Use VAT® FLEX RAPID for fixing translucid stone, clear marble and transparent parts, because thanks to their quick drying action, prevent stains and efflorescence.
  • Use PROPAM® CEM RAPID to attach the anchors to the support.

Technical mortars

Build a barbacue

Making barbecues, chimneys, ovens, etc., requires using specific materials that withstand the extreme conditions to which they are going to be exposed (high temperatures, expansions and contractions, etc.). The solution lies in using PROPAM® REFRACTARIO, a refractory mortar which, due to its technical characteristics, is suitable for coating walls and making joints that are subject to environments in contact with fire or high temperatures. The abrupt changes in temperature that occur when lighting barbecues, fireplaces, ovens, etc., produce dilations. When turning off facilities, contraction movements in the materials used are produced. These changes can produce cracks and even lead to loosening, if the materials used for its...

Build a wall with glass blocks

A glass block is a very useful material both in construction, decoration and interior decoration, as it can be used to separate different ambiances, showers, outside walls, or simply as decoration. It is formed by two pieces of molded glass, which are welded at a very high temperature, to create a vacuum air chamber between the two pieces. This air chamber confers the capacity of thermal-acoustic insulation. Once placed provides highly decorative finishes, given the wide range of formats and colors.

Fixing glass wool in an enclosure chamber

The need to obtain efficient thermal insulation and even more so since the TBC came into force a few years ago, has lead the construction industry to develop materials like glass wool, for use as thermal insulant and acoustic absorbent in enclosure walls inresidential, commercial, industrial and service buildings. For its correct placement it is necessary to use a mortar that allows the waterproofing of the enclosure against water that can penetrate from the outside, without forming a vapor barrier.
