Create a chemical barrier against rising damp

The humidity that rises from the foundations, also called rising damp, causes the degrading or deterioration of the lower parts of the walls, and unhealthy environments inside dwellings.

In general we know that the wall presents this problem when we observe that the mortar or plaster are in bad condition.

The wallpaper is peeled off, the frieze wood has decayed, the paint is peeling, or there is a strong musty smell.

The solution to this problem consists of making a horizontal chemical barrier in the wall base with PROPAM® CREAM, water-repellent cream based on siloxanes in aqueous dispersion

PROPAM® CREAM is injected with a gun into a series of pre-drilled holes.

Remove the ceramic or wooden skirting board, and remove the degraded plaster or mortar until it reaches the original substrate,

Make holes of 12 mm in diameter, horizontal in the plane coincident with the joint. Drill at least one course with a maximum gap between holes of 10-12 cm.

Always drill a hole at the intersections between the horizontal and vertical joints. The depth of the hole will be that of the wall, leaving a shelf of between 2 and 4 cm with respect to the other face of the wall.


Unscrew the tube.

Insert the bag into the tube,

Place the nozzle and screw the tube. The two sharp elements of the nozzle will pierce the bag allowing the output of PROPAM® CREAM.

To facilitate execution, insert a flexible cannula into the tip of the nozzle.


Insert the tube to the bottom of the hole.

Completely fill the hole, leaving 1 cm free to the surface. Then plaster or apply a mortar without having to cover the holes.


  • It is recommended to carry out pre-tests on the substrates in order to observe the possible changes of tone.
  • The product has not been designed for application as surface impregnation.

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. This operation must be...

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.
