• Fast and economical masonry
• Rapid increase in strengths
• Masonry is possible at temperatures as low as 1°C
• Masonry without expensive tools
• Masonry without electricity and water on site
• Bricks do not need to be moistened before mortar application
• Minimal site contamination
• Easy to interrupt and resume work
• Minimal storage requirements

With HELUZ SIDI mortar, construction is simplified and accelerated because applying mortar with a roller is as easy as painting. However, the masonry exhibits similar properties (mechanical, thermal, acoustic, durability) to those of cementitious thin-set mortar. HELUZ SIDI mortar is also suitable for passive houses.

Compared to the application roller, which costs five or seven thousand CZK, a system roller costing ten Czech crowns will now suffice. We will also supply it directly with the mortar and it is no problem to buy it in building stores if necessary.

HELUZ SIDI mortar is a thin-layered masonry mortar with a binder based on water glass and an alkali-resistant polymer dispersion ready for immediate use, i.e. a completely different material base than the cement mortars used so far. This type of material is well known to the construction industry, but not in the form of pre-formed masonry mortar.

The mortar formulation has also been developed to meet the requirement for a long lasting mortar worthy of brick construction. It has excellent wettability to brick rubble and sufficient open time for mortar application, brick placement and rectification in masonry. The optimum grain size of the mortar evens out minor irregularities in the bearing joints and distributes the stresses in the masonry evenly from the load. After application, the water evaporates or soaks into the brick, HELUZ SIDI mortar hardens and, thanks to the water glass, is strong and behaves similarly to cement mortar. Full joint hardening in normal climatic conditions occurs within 7 days, which is 4 times shorter than with conventional mortars!

The total "open time" is 10 minutes. And then within another 5 minutes the brick block must be placed in its final position in the masonry. This means that within a maximum of 15 minutes from the application of mortar to the bottom row of bricks, the brick must be settled into its final position in the masonry. The time for mortar application and brick placement is therefore roughly double that of cementitious thin-set mortars. This feature significantly increases productivity, as bricklayers do not have to interrupt the laying of bricks as often to harden the mortar and take care of the special application roller.

• Less waste material
• No residue

Compared to thin-film mortars, of which need to be transported to the construction site about half a pallet, a few buckets of HELUZ SIDI mortar will be enough for the construction site, which you can also store without any problems, as it will not be bothered by getting wet, as it is in a plastic bucket. You can just as easily transport it to another building site after opening and use it in a week or so without the risk of hardening, as with foams. Waste management is also easier. The buckets can be used for other activities on site and do not get in the way like scattered bags of standard mortar mixes. No mixing with water and no worrying about the application roller as with cementitious thin-layer mortars.

It is possible to use at temperatures above +1°C. The surface of freshly applied mortar must not be exposed to rain, as with conventional mortars.
