Limestone stucco applications

Using find mortars based on limestone, selected aggregate, synthetic resins and different admixtures provides highly decorative finishes, both indoors and outdoors, which imitate the traditional coatings with limestone stucco.

Use REVAT® CAL ESTUCO to obtain a fine limestone stucco with floated finish. Use REVAT® CAL FINO to obtain a fine limestone stucco, matt or glossy finish.

PREPARING THE SUPPORT

To obtain a regular, consistent and impermeable surface, render the support beforehand with REVAT® CAL ENFOSCADO. This  product can be applied manually using a trowel, or with a projecting machine.

APPLICATION AND FINISHING REVAT® CAL ESTUCO

Mix REVAT® CAL ESTUCO manually or mechanically with the indicated amount of water, and form an even paste, smooth to the touch. Respect the mixing water to prevent changes in colour tone.

With a trowel, spread the paste over the set and hardened support of REVAT® CAL ENFOSCADO, between 2 and 4 mm thick. The work joints can be limited with adhesive painting tape.

The final finish is obtained by gently floating the surface with a fine sponge trowel.

SURFACE PREPARATION FOR FINISHING REVAT® CAL FINO

Spread over the REVAT® CAL ENFOSCADO set and hardened support, a layer about 3 mm thick of REVAT® CAL ESTUCO, float and leave to dry.

APPLICATION AND FINISHING REVAT® CAL FINO

Mix REVAT® CAL FINO with the necessary amount of water to obtain a smooth, even paste.

Spread over the dry surface of REVAT® CAL ESTUCO a layer about 1 mm thick of REVAT® CAL FINO approximately, smoothing it with a stainless steel trowel.

  • Matte finish: a single pass with the trowel without making any revisions.
  • Gloss finish: smooth and polish with the trowel until the gloss appears.

Recommendations

  • In walls where adherence is difficult, use the REVAT® CAL FONDO primer before applying REVAT® CAL ENFOSCADO.
  • Do not apply in direct sunlight or strong winds.
  • Do not apply if there is a risk of rain or freezing temperatures.
  • Apply at a temperature of between +5ºC and +35ºC.
  • Do not apply to areas immersed in water.
  • Protect the lower parts of buildings with base plates.
  • During application, protect the areas exposed by rain.
  • In outdoor applications it is advisable to protect using REVAT® PROTEC ORG.

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.
