Grouting and cleaning cement joints

Before starting to fill in the joints between the ceramic tiles, it is advisable to consider the type of surface to be used:

  • Rustic or extruded stoneware usually has a rough surface which particularly makes cleaning difficult.
  • Fired-clay or terracotta, like any other coating with a very absorbent surface, requires a prior protection treatment to prevent moisture entering the grouting mortar.
  • On the other hand, as enamel surfaces are smooth, without pores or roughness, they are easy to clean.

Once the surface to be grouted is clean and dry, start mixing the grouting mortar BORADA® PORCELÁNICABORADA® UNIVERSAL or BORADA® PLUS using a mechanical mixer. The mixture appears creamy, consistent and smooth.

Apply the mortar diagonally to the joints, as this will help fill them completely. In turn, with the same accuracy, remove as much excess material as possible, as this will help subsequent cleaning.

Wait until the mortar’s surface shine disappears (approximately 15 minutes); by then it will have started to harden and the surface can be cleaned. To make it easier, rub the surface with a slightly moistened steel wool pad or sponge.

Once the joint is completely hardened, use a damp sponge to remove any surface film (veil) and use a wet sponge for a uniform, comfortable and definitive cleaning. During cleaning, do not use too much water as that will disperse the pigments and cause efflorescence.


  • Grouting must be done 24 hours after the ceramic tiles are fixed.
  • It is advisable to slightly wet the edges of the very porous tile joints.
  • After applying BORADA® UNIVERSAL, the pavements can be walked on after 3 hours.
  • BORADA® PORCELÁNICABORADA® UNIVERSAL and BORADA® PLUS can be applied with a refillable gun.
  • The amount of product to use depends on the thickness and width of the joints, and the size of the ceramic tile.
  • For decorative grouting antacids, bacteriostatic and use fungicides on board up to 20 mm BORADA® EPOLUXE or BORADA® EPOXI.

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.
