Application
1. Blok-Lok™ with Grafti Control should be
applied using low pressure airless spray
equipment.
2. Avoid atomizing material by using a spray
tip size of .035 to .051. Spray head should
be held 8 to 12 inches from the surface
so that the ood coat runs down the wall
approximately 6-12 inches below the point of
application.

avoid using excessive materials. Stop all
applications only at corners, joints, seams, or

Description
Blok-Lok™ with Grafti Control is a water-based,
silane/siloxane grafti & water repellent that

component, to create a clear, deep-penetrating,
and non-lm-forming chemically-reactive
masonry water repellent that contains no silicone
oils, parafn wax, or urethanes.
Micro-Lok™ creates a micro-molecular chemical
and mechanical bond between the water-
repellent chemicals and the substrate. Blok-
Lok™with Grafti Control penetrates deep into
porous masonry surfaces to provide long-lasting
and virtually indestructible water-repellent
