Grouting and cleaning joints in a swimming pool

The aesthetical quality of a swimming pool is conditioned both by the correctly applied ceramic coating and the implementation of the arrangement joints.
The visual appearance of the section defined by the joints is going to depend on careful grouting.

Grouting must be done with BORADA® PORCELÁNICABORADA® UNIVERSAL or BORADA® PLUS 24/48 hours after fixing the ceramic tiles.

Avoid the adhesive mortar filling in the gap reserved for the joint, because if grouted it could cause a change in the colour tone and affect the joint’s mechanical properties.

To improve aesthetics and facilitate grouting, first remove any adhesive mortar remains from the edges of the joints.


Fill in the joints using the hard rubber trowel, spreading the product diagonally and pressing the joints (it can also be applied using a refillable gun).

Wait until the mortar´s surface shine disappears, which is usually within 10 minutes (BORADA® UNIVERSAL or PLUS) or 30 minuts (BORADA® PORCELÁNICA). Clean with a slightly moistened sponge and rinse out frequently.

Once hardened, remove any remains by cleaning with a clean, dry cloth (wait at least 8 hours with BORADA UNIVERSAL or PLUS). Do not use too much water as that will disperse the pigments and cause efflorescence.

When working in the pool vessel where only the ceramic coating is grouted: if the joint is filled with BORADA® UNIVERSAL or BORADA® PLUS,the pool can be filled 24 hours after applying the joint.


  • Do not apply in full sun, hot surface or in rainy weather.
  • The grouting must be carried out after a minimum of 24 hours after the ceramic fixation.
  • If the renovation of the ceramic covering of the pool glass is complete (ceramic and cement joint), it is necessary to wait at least 2 or 3 weeks to fill the pool.
  • In case of pools with high demands can also be used BORALÁSTIC with BORADA® PORCELÁNICA or BORADA® UNIVERSAL.
  • For greater durability of the joint in swimming pools (public, thermal, sports centers …), use BORADA® EPOLUXE as a grouting material.
  • With BORADA® EPOLUXE wait a minimum of 3 days since the application, for filling the pool.
  • The consumption of the range of joints BORADA® varies according to the thickness and width of the joints, as well as the dimensions of the ceramic material.

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.

Making quick fixings in masonry

Masonry tasks like arrissing, small anchorings, door and window framing, attaching pawls, sanitary units, hinges, etc., require the use of quick hardening mortars that can provide very high mechanical resistances in a few minutes.  The solution lies in using PROPAM® CEM RAPID, that is, a mortar formulated on the basis of high resistance cements and special quick setting and hardening admixtures.

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.
