A-Class waterproof coatings cover three products for three different jobs: Fiber King 500, a water-based elastic coating with micro-fibre reinforcement for concrete roofs and decks; 308 Waterproof Adhesive, a transparent brush-applied coating that dries clear; and No-Hack 221, a two-component transparent coating applied straight over existing bathroom tiles without hacking. Sizes run from 500g tins to 20kg pails.

Which coating for which surface

Fiber King 500 — concrete flat roofs, decks, asbestos and metal roofs, external walls. The micro-fibre reinforcement lets the membrane stretch across hairline cracking instead of splitting with it. Full system 1.9 kg/m², so a 20kg pail covers about 10.5 m².
308 Waterproof Adhesive — roofs, walls, bathrooms, kitchens and window sills where the surface must still look the same afterwards. Dries clear. Mould proof and antifouling.
No-Hack 221 — bathroom floors and walls over existing tiles. Two-component kit, Part A 600g plus Part B 300g hardener. Saves the hacking, the disposal and the retiling.

What a coating cannot fix

Worth saying at the counter, because it prevents a return: waterproof coatings bridge hairline cracks and seal porous surfaces. They do not repair structural cracking, corroded reinforcement, failed flashing or a broken pipe inside a wall. Where water is coming from one of those, the coating will hide the problem for a season and then the customer is back. Diagnose first, coat second.

Documentation, and what it means for stock

Commercial and industrial jobs ask for a safety data sheet before the material goes on site, and a shop that can produce one the same day keeps the order. The Fiber King 500 safety data sheet is published here in Bahasa Malaysia and can be downloaded and forwarded without asking us first.

It also settles a stocking question. Fiber King 500 is not classified as dangerous goods for road, sea or air transport and carries no UN number, and section 15 records it as not regulated. It ships as general cargo and stores as ordinary stock — cool, dry, ventilated, and not shelved against strong oxidisers, caustics or acids. Sheets for 308 and No-Hack 221 are on request while we obtain them from the factory.

Buying waterproof coatings by the carton. A-Class supplies the trade only — hardware shops, plumbing merchants, contractors and project buyers. Minimum is one carton per item, and carton quantities are printed against every code above (500g tins to 20kg pails). Prices are not published: wholesale pricing depends on quantity and trade account, so it is quoted per enquiry.
