The PSI Poly-Tuff line at Latux
The PSI products we carry are liquid-applied elastomeric waterproofing: membranes that stretch with a deck and come back, for balconies, walkways, parking decks, plaza decks and below-grade walls. Contractors call it a traffic coating or a deck coating. You never buy one pail. A PSI deck is a primer, a base membrane, reinforcement at the cracks and joints, and a top coat, and every product on this page is one of those parts.
The names tell you the job. Enviro-Grip is a primer. P-Tuff, B-Tuff and T-Shield are base membranes. Top-Shield and Topshield are top coats. PTS covers the sealant and the detail membrane. The rest handles prep, reinforcement, cure, body and color. How the layers go together, deck by deck, is on the deck waterproofing guide.

Which PSI products are named in the Miami-Dade NOA
Miami-Dade County, Florida NOA No. 25-0604.15, expires 03/06/2031 (March 6, 2031), covers the Flexideck C-WD waterproofing system from Polytuff Systems International on concrete decks. Three products on this page are named in it: Top-Shield 5600EF as the top coat, P-Tuff Classic as the base coat, and the Enviro-Grip EP#2 primer, of which Enviro-Grip ep#2sc is the low-VOC grade. The acceptance covers the assembly as a whole, not any one product on its own, and not the other products here. The assembly table and what a permit job needs are on the deck waterproofing guide. The full Notice of Acceptance is available on request.
We supply PSI and we install it
The NOA requires the work to be done by a contractor licensed for roofing and waterproofing who is a manufacturer trained Qualified Applicator of Polytuff Systems International. Latux is on the Polytuff Systems International approved applicator list, so the company that sells you the system can also put it down. We install in Broward, Miami-Dade and Palm Beach counties. Outside those, we work with a network of installers across the US.

Common questions
Where can I buy Poly-Tuff waterproofing?
From Latux, by quote. Call (800) 413-1427 or message your rep, then pick up in Pompano Beach or have it delivered.
What is P-Tuff Classic?
The single-component, water-catalyzed polyurethane base coat of the PSI line. It goes on from a feather edge to 3 inches in one application, so it also fills ponding areas.
Does Latux install PSI deck coatings?

Is every PSI product covered by the NOA?
No. The NOA names three products as parts of one assembly: Top-Shield 5600EF, P-Tuff Classic and the Enviro-Grip EP#2 primer.
