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.

Check the condition of the substrate, it must be completely set and clean of dust, paint, oils, etc …

It is essential that the substrate is perfectly levellled, only this way we can get a correct placement of the glass blocks.


Knead PROPAM® GLAS with a slow electric mixer (500 rpm) until a smooth, homogeneous mass is obtained.

Reinforce joints between blocks with galvanized steel rods of 4 mm diameter, without coming into contact with the blocks.

Apply PROPAM® GLAS on the glass blocks and place them with the help of crosspieces.

Remove the excess of paste and proceed to the final finishing of the joints with the help of a rubber trowel, if necessary, the final finish of the joint can be profiled with the aid of a pointer.

Dispose off existing debris by wiping the surface with a clean, dry cloth.


  • Do not apply in rainy conditions, nor with temperatures below + 5 ° C or above + 30 ° C.
  • Leave a minimum joint between blocks of 10 mm.
  • The partitions that exceed 3 meters in width will have galvanized rod in each vertical joint.
  • Every two rows fix a galvanized anchoring profile at both ends of the panel.
  • The glass blocks are not structural so they will never carry any load.
  • The maximum area of one side of the partition wall shall not exceed 20 m2
  • In the face of possible dilations and contractions, place an elastic perimeter seal to protect the walls or window openings in direct contact with the glass blocks.

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...

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.

How to solve humidity problems in skirtings

The deterioration of the lower parts of walls due to humidity ascending via capillary action from the foundations, is one of the most common construction faults in buildings. The moisture coming from the ground penetrates the foundation and rises through it towards the upper walls by capillarity. The salts entrained during this process, are deposited inside the wall and in the renders. The continuous presence of water and moisture in the wall produces the hydration and increase of volume of these salts, which causes the destruction of the wall and the render. The phenomenon is all the faster the greater the amount of water and salts present in the system. The solution is to use PROPAM® SEC, ie a water-repellent mortar, impermeable...
