After all, it usually takes weeks from applying the slurry and drying the wet or damp wall until it can be re-plastered and the renovation completed, as intermediate layers often have to be applied. However, this is not the case when using AREXAL products! As these are optimally coordinated and can be applied wet-on-wet, plastering, for example, can be carried out directly after waterproofing using crystalline grout - without weeks of drying and waiting time and without additional intermediate coatings. This is an enormous time advantage for you and for every craftsman and specialist company, as it is possible to dry out other properties much faster.

Mineral waterproofing products with over 70 years of experience

The crystalline technology has been continuously developed and improved for over 70 years and offers clear advantages over the well-known and traditional alternatives. Many of the laguz sealing products contain silanes, which cause crystal growth through the pores and capillaries of the structure. The crystals grow by using the surrounding water for their development and displacing excess water from the structure. An indestructible, permanent crystalline layer forms in the structure, filling every pore or capillary and forming a permanent seal against water. With repeated water ingress, the crystals simply continue to grow up to a depth of approx. 20 cm into the material and force the water out again.

Since the crystalline products need the water that has penetrated the masonry, the masonry does not even have to be completely dried out. The layers of the crystalline slurry can be applied wet in wet one after the other and immediately afterwards (approx. 20 minutes) the Restoration plaster to be applied. This represents enormous time and cost savings for the customer and the craftsman.

The advantages are:

  • The masonry is not completely drained = wet-on-wet processing
  • Crystals compact the masonry into a waterproof layer
  • Crystal growth into the structure when water ingresses again
