PREPARATION

Combine ingredients in a trough and mix together with trowel or hoe.

The putty and filler must be worked together until the mixture is completely homogonous.
There can be no lumps of putty, even tiny ones. Cut into the mixture to test it.
If any white specks of putty are visible continue mixing no matter how long this takes.
Water may be added if needed to form a plastic mortar which can be spread onto a wall with a trowel.
