Fixing ceramic tiles in swimming pools

Due to the demanding conditions of use in a swimming pool, the materials used are put to a hard test.

The seat of the swimming pool and the pressure and counterpressure of the water subject the tiles to very considerable stress.

The products used for swimming pool maintenance and care can have an aggressive effect on the arrangement joint. To guarantee that the tiles are fixed well, both the adhesive and the grouting material must be able to withstand these chemical attacks, have high adherence and excellent behaviour in water. In some cases it may be necessary for joints that prevent the development of mould. Take into consideration that the swimming pool must, on its own, guarantee watertightness to prevent leaks, and that the ceramic coating is a complement to the waterproofing.

PREPARING THE SUPPORT

Make sure that the pool is watertight by filling it beforehand, this way we can make sure that there are no water leaks.

Check the suppot, it must be hard and strong; remove any weak areas from the surface, or cement slurry, remains, dust, paint, etc.

APPLICATION

Mix with a slow electric mixer (500 rpm) and spread VAT® EXTRA over the support using a notched trowel, using small work areas to prevent a surface film or crust from forming, which could hinder the adherence of the ceramic coating.

Fix the tiles ensuring they form a solid surface.

Do the joint filling 24 hours later with BORADA® PLUS.

The swimming pool can be filled 21 days after grouting. This time margin is needed to allow the mortars to set correctly and harden.

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 at 50%.
  • For fixing low absorption tiles larger than 100 cm2, use VAT® PORCELÁNICO FLEX.
  • In swimming pools with very demanding conditions, it is advisable to use BORADA® EPOLUXE.

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.
