What the assessment covers — and what it leaves on the TDS.

A membrane that moves at laboratory temperature can still tear at minus ten.

Three numbers that decide a shift. Weather apps are not an application window.

A fully adhered membrane may sit under standing water only if the written system is rated for it.

Pinholes are outgassing and porosity. Blisters are moisture or vapour under a fresh film.

Two-component kits fail in the pot. Mix the whole kit to the A:B on the current TDS.

A pool on a roof is a tank and a roof at once. The catalogue does not invent a build-up mass.

Vertical stands, horizontal roofs and self-levelling floors are different liquids.

A gardened roof is a roof, a root barrier and a drainage build-up.

Catalogue 2024 keeps the names apart. Do not collapse them into one generic polyurea.

Class by traffic. Never by a sample. Primer, body, finish.

Bleachers are waterproofing with a fire class. They are not a resin floor.

Containment and tanks. Abrasion, chemicals, corrosion. No invented jobs.

Pontoons, ramps, decks. Seawater, salt, sun. Seamless protection.

Drinking water is a named exposure. WRAS sits on Polyurea Rayston.
