Porrathin® mortars and adhesivesLightweight insulating bricks
The Porrathin® products were specially developed grouting of lightweight refractory bricks.
The absorbency is optimized so that the bricks to be grouted can be properly coated and inserted into the masonry without the masonry prematurely drying or floating away.
Porrathin is usually delivered ready for use. Only the two types of mortars Porrathin 34 and Porrathin 34-R for high temperature refractory bricks are delivered dry.
