Levelling and subsequent fixing of a light pavement

Recently parquet floors have become a common decorative element, both in homes, industrial premises and supermarkets. To obtain quality finishes, with this type of light pavement, and with any other (carpet, PVC, rubber, etc.), it is necessary to provide a substrate that is dry, flat, level and clean.

The solution lies in using NIVELANTE 10, that is, a self-levelling mortar with excellent levelling capacity and quick hardening properties, which allows repairing and smoothing indoor surfaces of concrete, mortar and the like, before installing this type of coatings.

PREPARING THE SUPPORT

Check the condition of the support; it must be completely set and clean of dust, paint, oils, etc.

Check any smoothness differences. The maximum application thickness will be 10 mm per layer.

Repair all the gaps and deteriorated areas with the same levelling mortar NIVELANTE 10, or with PROPAM® REPAR 5PROPAM® REPAR 40 or PROPAM® REPAR TECHNO if the support is concrete. Prepare the bracket with a primer prior to the application of NIVELANTE 10:

  • Porous media: PROPAM® PRIMER SOL.
  • Non-porous media: PROPAM® GRIP.

Respect of expansion and contractation joints.

APPLICATION

Mix NIVELANTE 10 with a slow electric mixer (500 rpm), leave to stand for 2 minutes and mix again so that the paste is ready to be used.

Pour NIVELANTE 10 on to the support and spread with a trowel to make levelling easier. Use a wire  brushes to deaerate the mixture and facilitate the levelling.

If applying a second layer, this must be applied as soon as the first layer can be walked on (approx 4 hours). The thickness of each layer may not exceed 10 mm).

To coa with  wooden, PVC or paint, wait a minimum of 48 hours.

Recommendations

  • Do not apply on floors with permanent humidity, or which are likely to produce humidity due to capillary action.
  • Apply at a temperature of between +5ºC and +35ºC.
  • If applying a second layer, the first one must not be allowed to dry completely, otherwise, a primer layer will be necessary using PROPAM® PRIMER SOL.
  • It is advisable to use PROPAM® DUR as a surface hardener for old mortars and concretes, before applying the product, and waiting 12 hours for it to dry.
  • Respect the mixing water and prepare the correct product mixture, without adding too much air.
  • On supports with underfloor heating, switch off the heating 24 hours before applying the product.
  • Do not apply outdoor, or on industrial floors.
  • On no porous supports applying PROPAM® GRIP like primer layer.
  • For levelling with underfloor heating, use NIVELANTE 80.

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. Related products PROPAM® REPAR 20RPROPAM® PRONTO Solution SUBSTRATE PREPARATION The substrate must be firm (minimum tensile strength of 1N / mm2), rough and free of oils, old paint residue, demoulding agents, dust, cement slurries, etc. Moisten the substrate with water before applying PROPAM® CEM RAPID.

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.
