Fixing ceramic tiles on plasterboards substrates

Dry partitioning is a building system made up of rectangular plates with a natural plaster web bound to two surface sheets of cardboard, used in indoor distributions. These plates are assembled on a structure with galvanised steel plated sections.

Any vibrations and bending this system may suffer are to be considered when selecting the correct fixing material to ensure it guarantees that the ceramic tiles can be secured firmly.

Make sure that the system is stable by checking the plasterboard panels are firmly attached.

Check that the support is dry and clean. (Brush the surface if necessary).


Spread VAT® EXTRA over the support using the notched trowel, and check that the adhesive’s open time has not elapsed.

Fix the tiles ensuring they form a solid surface.

Leave a minimum grouting joint width of 2 mm and regrout after 24 hours using the grouting range BORADA® by PROPAMSA.


  • For fixing large tiles (over 900 cm2) use the Floating and buttering technique.
  • The dispersion adhesives ensure optimum adherence even when the plates move or deform.
  • In very hot weather conditions, or strong winds, do not wet the support and use small cloths during application.

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.

Making quick fixings in masonry

Masonry tasks like arrissing, small anchorings, door and window framing, attaching pawls, sanitary units, hinges, etc., require the use of quick hardening mortars that can provide very high mechanical resistances in a few minutes.  The solution lies in using PROPAM® CEM RAPID, that is, a mortar formulated on the basis of high resistance cements and special quick setting and hardening admixtures. Related products PROPAM® REPAR 20RPROPAM® PRONTO Solution SUBSTRATE PREPARATION The substrate must be firm (minimum tensile strength of 1N / mm2), rough and free of oils, old paint residue, demoulding agents, dust, cement slurries, etc. Moisten the substrate with water before applying PROPAM® CEM RAPID. This operation must be...

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.
