Fixing porcelain stoneware

Porcelain stoneware is a very low water absorption ceramic tile, which is dry pressed with a wide range of colours and it is fired only once.

Thanks to its exception hardness and resistance, it is used on pavements as renders, ranging from conventional bathroom and kitchen coatings to more difficult arrangements on façades and high transit pavements.

To ensure that it is attached correctly to the substrate, an adhesive mortar with mixed binding agents has to be used, that is, which also contains resin as well as cementand provides the appropriate chemical adhesion.

Solution

PREPARING THE SUPPORT

Check that the support is strong, perfectly set and clean of any dust, paint, oil….

Wet the support if it is exposed to sunshine and/or if it has to be very absorbent.

Check the smoothness of the support with a 2 m long ruler; any differences must be less than 5 mm.

APPLICATION

Mix with a slow electric mixer (500 rpm), leave to stand for 5 minutes.

User VAT® EXTRA PLUS to place poocts up to 2000 cm2  (50 x 40) floring and interior finishe, and 1000 cm2  in outdoor.

User VAT® PORCELÁNICO FLEX to place part upto 3600 cm2 in outdoor and indor, and interior finishes.

Perfoorm double gluing  where the format of the piece exceeds 900 cm2 in 2000 cm2 in the case of paving or tiling.

Press the tiles so that they form a solid surface, thus avoiding any gaps between the tile and support.

Leave a minimum grouting joint width of 2 mm indoors, and 5 mm outdoors; regrout after 24 hours using the grouting range BORADA® by PROPAMSA.

Recommendations

  • Do not apply in wet weather, or with temperatures of <5ºC or >30ºC.
  • With poor absorbency supports, open the pore with water and hydrochloric acid to 50%.
  • When fixing tiles on façades, use PAM® FLEX or VAT® FLEXIBLE.
  • Used for sockets of facade of no higher than 2 m and directly on brick (in thicknesses up to 15 mm) use VAT® FLEX RAPID.

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.
