Hessler Naturkalk-Haftputz

Hessler Naturkalk bonding plaster has a fine grain size of up to 1 mm and is particularly suitable for bonding internal insulation boards or as a substrate for subsequent lime plasters. HP 14 is also a problem-solver for all difficult substrates.

Used as a bonding bridge, HP 14 creates a load-bearing layer for the subsequent plaster build-up. HP 14 has a dispersion content of well below 2%. This is considerably less than in conventional bonding plasters. As a result, HP 14 remains absorbent and is low in stress.
