Global technology. Guyanese focus.
Ceiling stains, peeling paint and mould that keeps coming back. Rust creeping across a metal roof. Water pooling on a flat roof after every downpour. One patch on top of another — and it still leaks. Most roofs don't need replacing: they need sealing, properly, in one continuous layer.
WetSuit® is a liquid membrane — membrane technology. We spray it directly onto your roof, where it forms one continuous waterproof skin with no joints and no seams — because seams are exactly where water gets in. It seals every crack, screw hole and edge, sticks tight to the surface, and flexes with heat and movement instead of cracking.
Our main roof coating and the finishes that complete the job — explained simply. The full technical names and data stay in the system details below, for engineers and specifiers.
“The fast one.” Our main roof coating: sprayed on, it sets in seconds and is ready for rain almost at once.
“The versatile one.” Sprayed, brushed or rolled — ideal for smaller jobs, details and repairs.
The finishing kit & the complete system
The two-component system uses a catalyst to create its instant set. The cold-sprayed membrane adheres fully to the substrate, flashes itself around details and can be built to the specified thickness in one pass without running or sagging on vertical work.
The single-component, self-leveling membrane has chemistry and physical properties similar to WetSuit® 2-Part without the instant-set catalyst. It can be sprayed, brushed or rolled, with Invisilink™ reinforcement embedded at seams and joints when the specification calls for it.
A water-based, self-leveling membrane used beneath or between WetSuit® products. Combined with Invisilink™ fabric, it pre-strips joints, penetrations, edges and cant strips, and levels localized areas before the main membrane is applied.
WetSuit® Trowel is a high-viscosity patching compound for cracks, joints, tears, penetrations, ducting and flashing details. Fiber Trowel adds fiberglass reinforcement for higher-tensile, low-elongation patching at high-movement penetrations and joints.
Prime Mate is a water-based acrylic primer for PVC, Hypalon and aged TPO surfaces, designed to promote adhesion and resist plasticizer migration. Invisilink™ is the reinforcement fabric used at seams, joints and other details, or throughout a fully reinforced assembly.
The correct assembly starts with the existing surface, exposure, movement, drainage, details and intended use. Guyana WetSuit reviews those conditions before recommending membrane, preparation, reinforcement and finish requirements.
Complementary Neptune coating families
HarcoSil 19-97 and 29-97 are silicone elastomeric roof coatings that cure into durable, breathable, weatherproof barriers with strong resistance to ultraviolet exposure and natural weathering. They can be specified as stand-alone roof coatings or as reflective topcoats over a compatible WetSuit® membrane assembly. Harseal 1959 supports the system at fasteners, penetrations and transitions.
“The cool one.” The REFLEX™ family is a reflective acrylic elastomeric roof-coating system compatible with WetSuit® and suitable for stand-alone restoration of low-slope and metal roofs. The family includes high-reflectance HPW, low-glare HPG, quick-set QS30, W200 topcoat, Bleed Blocker base coat and Flashing Grade detail coating.
HARCOAT CIC-1000 is a waterborne, single-component ceramic insulation coating for process equipment and piping. It forms a seamless thermal barrier that helps control condensation and protects personnel around operating temperatures up to 180°C / 356°F, with high-build application up to 1.5 mm dry film thickness in one coat.
One continuous skin of liquid membrane, sprayed over the roof you already have — built for Guyana’s sun, coastal air and heavy tropical rain.
Four simple steps — and in most cases your building stays in use while we work.
We visit, find where the water is getting in, and check the condition of your roof. No charge, no obligation.
The right system for your roof, at a price agreed before we start — no surprises.
We clean and repair the surface, seal the weak points, then spray the coating in one go. It sets in about 3 seconds and can take light rain almost immediately.
You get a written warranty of up to 30 years — and a local team in Georgetown if you ever need us.
The process in detail
We begin with the existing condition: substrate type, soundness, moisture pathways, drainage, ponding areas, transitions, penetrations, movement points and previous roof or waterproofing layers. Access and operating conditions are also reviewed before work is planned.
The findings guide the choice between WetSuit® 2-Part, WetSuit® 1-Part and the supporting products. The application method, preparation standard, reinforcement, target thickness and finish are set for the actual substrate and exposure.
The substrate is cleaned and made ready for adhesion. Loose or unsound material, contamination and defects are addressed, and the specified primer is applied where the surface requires it.
Joints, seams, cracks, edges, penetrations, cant strips and changes in plane are treated before the field membrane. UnderCover, Invisilink™ reinforcement, Trowel or Fiber Trowel are incorporated where the approved detail requires them.
Trained crews spray, brush or roll the specified WetSuit® membrane as required, maintaining continuous coverage and the specified thickness across the prepared field and completed details.
The completed surface and critical details are reviewed for continuity and coverage. Any specified finish or reflective topcoat is completed before the protected area is returned to service.
Homeowners: stop the leak and protect the house. Hotels, offices and commercial buildings: fix the roof without closing the business or tearing off the old one. Engineers and industrial clients: the full technical data is in the applications below.
Explore applications
A fully adhered, monolithic WetSuit® membrane can restore many existing roof assemblies without introducing new field seams. Applications include modified bitumen, aged spray polyurethane foam, standing-seam metal, wood and concrete, subject to inspection and the specified preparation.
Cold-applied WetSuit® membranes can protect vertical and horizontal surfaces above or below grade. Typical uses include foundation walls, split slabs, plaza decks, planter boxes, ponds, fountains and shower-pan assemblies, with compatible protection and finishes where required.
Because the membrane is seamless, fully adhered and low-permeance, WetSuit® can form part of a continuous air and vapor control layer. Details at transitions and penetrations are integrated so the barrier continues across the building envelope.
On suitably prepared metal roofs and structures, the bonded membrane covers fasteners, seams and cut edges while providing a waterproof barrier. The existing metal and supports must first be confirmed as structurally sound.
WetSuit® has also been used for containment, compatible water features and encapsulation projects. These applications require a project-specific review of the substrate, contained material, regulatory requirements and complete protective assembly before specification.

Straight answers, in plain words. Anything else — ask us on WhatsApp, or book the free inspection and we'll look at your roof in person.
It depends on the size and condition of your roof. The inspection is free, and you receive a fixed written quote before any work starts.
Usually not. If the structure is sound, we restore it in place — less mess, less downtime, lower cost.
Most roofs are completed in days, not weeks — and the coating itself is rain-proof in seconds.
Up to 30 years in writing on complete systems.
