Adimar Gypsum has special characteristics for laying tiles, medium/high porosity stoneware, in interior cladding, on traditional gypsum plaster substrates, plates and prefabricated gypsum panels, suitable for anhydrite substrates. Not suitable for exterior use.

• Preparation of the substrate: the substrate on which the application is to be carried out must be resistant, dry, level, free of dust and free of any traces of release agent.
• Preparation of the mixture: add 6-6.5 l of water per bag and mix manually or mechanically with a low speed electric mixer to eliminate any possible presence of lumps in the paste, allow the mixture to stand for 5 min. and carry out a brief re-mixing.
• Application of the paste: apply the product on the substrate using a toothed flame, to regularize the thickness, in a maximum extension of 2 m2, applying sufficient pressure so that the minimum contact with the cement is 80%. Lay the tiles, pressing them until the grooves are flattened and the tiles are correctly set with the help of a rubber mallet. It is necessary to verify, with the fingertips, periodically that the adhesive has not formed a film on its surface, if this happens the product must be combed again taking into account that we are still in the margin of the open time of this (if the temporary strip since its application has exceeded the above mentioned open time the adhesive must be removed and reapplied).

• The application temperature must be between 5 °C and 35 °C on the substrate.
• Do not apply outdoors.
• Avoid application on weak plaster. If necessary apply a surface treatment of hardening by means of a primer.
• Do not apply on substrates with residual humidity > 5%.
• Check the planimetry of the support with a 2 m ruler, verifying that the deviations must be less than 5 mm. In the case of Check the planimetry of the support with a 2 m ruler, verifying that the deviations must be inferior to 5 mm. In the case of superior deviations it is necessary to regularize them before the placement.
• Do not use in areas where there is danger of stagnant water.
• It is advisable to leave a minimum joint between tiles of 2 mm, applying UNIVERSAL JOINT 0/15 or TECHNICAL JOINT 0/16.
• On very absorbent substrates it is advisable to moisten it and wait until it is dry.
• Check the solidity of the finishing plaster of the prefabricated plaster.
• To install low absorption porcelain stoneware tiles on gypsum substrates, use Adimar Porcelánico or Adimar Flexible. If there are larger deviations, these must be regularized before installation.
