Aqua Stop Waterproofing uses the following WetSuit products:

WetSuit® 2-Part is a cold spray applied instant set membrane which is catalyzed to form a seamless, waterproofing membrane.

Wetsuit UnderCover is a single component, medium viscosity, material used exclusively underneath the WetSuit® System to pre-strip joints, penetrations, or detail transitions.

WetSuit® Trowel has the waterproofing characteristics of the 1 and 2-Part products, but is thicker. Ideal for patching cracks, voids and penetrations.

WetSuit® 2-Part Fluid Applied Membrane

The WetSuit® liquid membrane is a fully self adhered, cold spray applied, self-flashing membrane with a wide variety of uses for virtually all above and below grade applications. It can be sprayed to any mil thickness in a single pass thus creating a truly custom and precise membrane allowing unparalleled architectural freedom and ease of application.

The Healthier and Safer Coating Alternative

The water-based, no VOC, low pressure, cold spray applied, non-flammable features of WetSuit® eliminate job hazards such as torches, solvents, and heavy equipment.
Unrivalled Quality & Versatility FM testing proved to put WetSuit® in a class of its own. It is one of a select few materials on the market with a Class A fire rating, severe hail resistance, 1600% elongation and a wind uplift of Class 1-990! In addition, WetSuit® is proven as a viable air and vapor barrier. With very low perms, WetSuit® can be employed not only in below grade applications and roofing, but in between as a seamless, fluid applied vapor barrier as well.

Time and Money Saving

Because WetSuit® is so lightweight and with excellent adhesion to most roof surfaces, the need to tear off existing roofs is most often eliminated, greatly reducing installation costs and environmental impact. Surface preparation is generally limited to pressure washing the old roof to provide a clean surface for WetSuit® to adhere to. Utilizing only one applicator, WetSuit® can be installed at a fast and efficient rate of 1500 sq ft per hour, reducing crew size and job time.

Energy Star® Cool Roofs

The WetSuit® System will be top coated with a range of reflective coatings to meet Energy Star® and CRRC standards for “cool roof” reflectivity. For a list of approved topcoat manufacturers contact Neptune Coatings.
