Porcelain tile installation

Porcelain stoneware is a ceramic tile with very low water absorption, dry pressed, with a wide range of colours and a single firing.

Due to its exceptional characteristics of hardness and resistance, it is used both in flooring and in cladding, from the classic installation in bathrooms and kitchens to the most demanding installations on façades and floors with high traffic.

In order to properly attach it to the substrate, it is necessary to use a mixed-binder adhesive mortar, i.e. one that contains resin in addition to cement, and which provides adequate chemical adhesion.

PREPARATION OF THE SUBSTRATE

Check that the substrate is resistant, perfectly set, free of dust, paint, oil…

Moisten the substrate if it is exposed to the sun and/or very absorbent.

Check the flatness of the substrate with a 2 metre ruler; differences should be less than 5 mm.

APPLICATION

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

Spread VAT® EXTRA-PLUS, VAT® PORCELANICO FLEX, VAT® FLEXIBLE, PAM® ECOGEL FLEX, PAM® ECOGEL PORCEL, PAM® ECOGEL SUPERFLEX on the substrate using a notched trowel, according to the limitations of their corresponding technical data sheets, recommending double gluing when the size of the piece is greater than 900 cm² in tiling or greater than 50 cm on one side in the case of flooring.

Press the tiles in order to achieve a correct solidification of all the pieces, thus avoiding the existence of gaps between the tile and the substrate.

Leave a minimum joint width of 2 mm in interiors and 5 mm in exteriors; grout after 24 hours with the BORADA® range of joint mortars by Molins.

Recommendations

  • Do not apply at temperatures < 5º C or >30º C.
  • On poorly absorbent substrates, open the pore with water and 50% hydrochloric acid (salfuman).
  • For façade installation usePAM® ECOGEL FLEX, VAT® FLEXIBLE, PAM® ECOGEL SUPERFLEX.
  • For fast installation use VAT® FLEX RAPID.
  • Due to the different support options and part sizes, please refer to the corresponding product data sheets for limitations.
