Application Details
Regarding the choice of the appropriate width, widths greater than 25% of the width of the joint must be used to prevent the putty from overflowing the bottom of the joint when being trimmed to smooth it.
The installation is carried out by lateral compression of the joint bottom against the lips of the joint. It will be introduced at the previously defined depth using any auxiliary device similar to a wooden T.
