Using Chemind’s PRIMER W, the primer should be applied to the floor and wall with the height between 20-30cm with paint roller. Best is to start with the wall then move on to the floor as the excessive primer from the wall will flow to the floor. Ensure all large cracks and gaps are filled before applying the primer.
