Application Methods
Applied with brush, roller, or spray. Any airless sprayer with tip size 17-21 and PSI of 2500min-3300max can be used for spray application.
Minimum two coats required. Additional coats can be applied for added protection. Nonskid aggregate can be broadcast into wet base coat, then covered with second coat to reduce slippage.
Perfect Standalone Solution
Ideal for outdoor tiled, wood, or concrete substrates on roof decks above occupied areas. Functions as both waterproof membrane and finished surface with aesthetic color. For additional protection, apply Armor Shield Topcoat.
Waterproof Base Layer Application
Can also be used as a waterproof layer on roof decks or balconies that will have tiles, pavers, or wood flooring applied over it. Solves the persistent problem for homeowners and businesses requiring a finished floor over waterproof protection.
Super Durable with High Abrasion Rating: Handles deck chairs and tables, high foot traffic as a finished coating—or provides robust protection under pavers, tiles, and wood flooring.

5-Year Warranty!
Lighter colors may have bleed through from darker colors underneath. Order optional high pigmented topcoat to resolve this issue.
Minimum of two coats are required and you will get more coverage with the second coat. So on average you will get about 200 sf/gal over concrete and wood and 300 sf over nonporous surfaces such as tiles.
This product is designed to be applied in multiple thin coats, too thick a coat will cause product not to cure which is not covered under the warranty. Better to apply 3 or 4 coats than 2 coats that are too thick.
All surfaces must be clean and dry. Use Deck cleaner on wood and prior coatings. Remove any loose or flaking coatings and all petroleum based coatings. Can be used over Latex or epoxy coatings. Epoxy coatings should be sand to roughen up. Use an concrete etching product for all masonry surfaces. Sand new wood to remove Mil finish. Application temperature must be between 35-90 degrees.
Cracks up to 1/8" can be coated right over, fill in deeper cracks with foam backer rod or compacted sand, cracks 1/4"-5/16" can be filled by using Sikaflex 1a Caulk(available at Home Improvement stores) up to a hair below the surface. Allow to cure per manufacturer instructions. Apply coat of Liquid Membrane and let dry approximately 45-60 minutes and apply second coat apply additional coat if needed to get flush with floor. For larger cracks use a good quality concrete floor patch material and for wood you can use paintable wood putty or Bondo.
Once floor is fully prepped apply a coating of Liquid Membrane with 1/2" nap roller at the coverage rate 125-150 sf/gal on porous surfaces, on most typical surfaces you will get 200-250 sf/gal, do not apply thicker. Thicker applications can cause product not to cure. It's better to apply multiple thin coats rather than a thicker coat. This product is meant to be applied in thin coats. Two coats are required for above grade applications a third & fourth coat can be applied if thicker coverage is required. Allow first coat to dry for approximately 1 hr, coating should be dry to the touch and not leave any fingerprints. After final coat inspect for any pinholes, bubbles or other defects, repair by applying some additional Liquid Membrane. Three coats are required for below grade and submerged applications. For above grade applications full cure is in 2-5 days and for below grade or submerged applications you must allow 7 days for full cure before back filling or filling with water.
Allow final coat to fully cure beofre applying topcoat if using. Apply topcoat at 250 sf/gal in one coat. Purchase 1 gallon of topcoat for every 2 gallons of membrane.
Joints between a deck and a structure should have a cant strip( available at Home Improvement stores) installed, apply a generous amount of construction adhesive at the joint, embed the cant strip, let cure overnight. Then as you're coating the deck apply the membrane over the cant strip and up 4-6" on the wall of the structure. This creates an angle joint between a wall and the floor which is much better than a simple 90 degree joint that you cannot get the porper amount of material applied to. You should always use a cant strip when coating a deck, roof or balcony.
For spray applications use sprayer with 2500-3300 psi and .95-1.6 GPM capacity. Use 0.521 or 0.631 reversible tip. Hose length to not exceed 100' at 3/8" diameter.
