Application

Max-A-Seal WP® can be applied using a brush, squeegee, or spray equipment. For effective coverage, apply 60 mils wet to achieve a 40 mils dry coating. The material should be applied uniformly, ensuring no translucence on the surface. It is easily sprayed with equipment such as a Graco GH833 Siphon Pump, using a 1/2” hose and a GHD 661 Spray Tip. In-line filters should be removed when spraying.
