Apply Piro Acrylic Sealant
AC120 by using a putty
knife on both sides on the mineral wool board with
a minimum density of 80 kg/m3.
Steps 1 - 5
Place prepared mineral wool
boards inside the expansion
joint at one of its edges.
By using a putty knife apply
Piro Acrylic Sealant AC120O
on mineral wool boards.
Fill the remaining expansion
joint with mineral wool boards
with a density of 80 kg/m3 with
Piro Acrylic Sealant AC120
applied previously, the same
way as in step 1.
Properly protected
expansion joint.
