Elevada resistência

EN 998-1:2016

Properties


Fast-setting cementitious adhesive with good workability. Due to its composition, initial mechanical strengths are improved. Quick start-up.


Composition


Cement adhesive with mixed binders, based on cement, resins, mineral fillers and specific additives.


Support


Plaster and cementitious screeds. Avoid direct application on plaster substrates. For other substrates, consult Primefix.


Application instructions



  • Knead Primefast with 6 liters of clean water (per 25 kg bag of powder) manually or with a slow electric mixer, until you obtain a consistent, homogeneous dough without lumps.
  • Let the dough rest for 2 minutes before applying and then mix lightly.
  • Apply the glue to the support in small areas, no more than 1 m2 to 1.5 m2 , using a notched trowel.
  • Press and adjust the ceramic pieces to obtain continuous and complete adhesion of the glue.
  • Periodic checking of the glue distribution on the part is recommended.
  • In the presence of poor distribution, use the double gluing method and/or a trowel with a higher tooth.
  • Maximum layer thickness: 6 mm.
  • Avoid placing wet items.
  • Check that the back of the parts to be glued is clean.
  • Respect the fractionation/construction joints, using technical profiles or mastics, which allow the absorption of tensions.
  • When placing ceramic tiles between 2 parallel boundaries (e.g. a corridor) there must be clearance between the end of the ceramic tiles and the obstacle or vertical slope.
  • Use spacing crosspieces, at least 2 mm for small formats, gradually increasing as the size of the part increases.
  • Scrape and clean the joint before the glue hardens.
  • Avoid adding product and/or water to the already mixed glue, particularly when it reaches the hardening process.

    • Grouting of Joints:

      • You can apply the grout after a minimum waiting period of 6 hours.
      • You can grout joints with Primecolour-Plus (Rapid) mortar.
