Words From Our Valued Clients

4.8/5

Best liquid tanking on the market

I've tried the blue stuff and the grey stuff from other brands, but AquaSeal feels thicker and covers better. The 25kg drum is a no-brainer for full bathroom refits.

Martin H. (MTH Plumbing)

So easy to apply

Just stir it up and roll it on like paint. It covers the joints in the plasterboard easily. I put two coats on as recommended and it formed a solid rubber skin.

Jenny L.

Saved my awkward shower

I had a shower with a curved wall and a bench seat. Using a mat system would have been impossible. This liquid membrane painted right over the curves perfectly.

Creative Bathrooms Ltd

Dries fast

The 3-hour drying time is accurate. I got the first coat on at 8am, coffee break, then the second coat on before lunch. Ready for tiling the next morning.

Paul R.

Great for gym showers

We used the 25kg drums to tank a row of showers in a commercial gym. It goes a long way and stands up to the heavy usage. Very durable.

Commercial Fitout Pros

Peace of mind

I'm a DIYer, not a pro. Using this gave me total confidence that my new ensuite won't leak through the ceiling. Cheap insurance if you ask me.

Steve G.

Excellent adhesion

My tile adhesive grabbed onto this surface really well. No issues with heavy porcelain tiles slipping or debonding.

L. Ferguson

No mixing mess

Love that it's ready mixed. No dusty powders to mix up with a drill. Just pop the lid and get to work. Keeps the customer's house cleaner.

CleanLine Tiling

Flexible skin

You can feel the flexibility when it's dry. I used it on a timber floor that had a bit of movement, and the membrane just flexes with it rather than cracking.

Harry T.

Good coverage

The 5kg tub did my whole shower enclosure (walls and floor tray area) with two generous coats. Good value.

Rebecca S.

Professional results

This is the only tanking I spec now. It's foolproof. If you miss a bit, you just spot touch it up. Guarantees a leak-free handover.

Elite Renovations

Tough durability

Dropped a trowel on the cured membrane by accident and it didn't even scratch. It really is tough stuff once it cures.

Your Questions, Answered

It is designed for ease of use. Simply stir well before use, then apply evenly to the substrate using either a wool roller or brush. This makes it accessible for both professionals and DIYers.

To ensure an Impenetrable Watertight Seal, the final thickness must be at least 1mm. We recommend building this up in layers rather than one thick gloopy coat.

You should apply a second coat 90° to the first coat. This "cross-hatching" technique ensures that no pinholes are missed and guarantees a uniform, seamless barrier.

The formula is Fast Drying. The first coat is usually dry in approximately 3 hours (at a temperature of +20°C). Once dry to the touch, you can apply the second coat.

5kg Drum (FAS50): Ideal for a standard domestic shower enclosure or small wet room. 25kg Drum (FAS25): Perfect for large commercial jobs, multiple bathrooms, or professional tilers who want to buy in bulk for better value.

Yes. AquaSeal is suitable for use in domestic and commercial situations. Its tough, durable nature makes it capable of withstanding the high demands of commercial wet rooms.
