Words From Our Valued Clients

4.8/5

The range of colours is incredible

I used 'Tornado' for a modern grey bathroom and it matched the tiles perfectly. Dries true to the colour on the bag.

James P.

Super smooth and professional finish

Some flexible grouts can be really coarse and gritty, scratching the tile. This is super smooth and leaves a really professional finish on polished porcelain.

Solid at 15mm joints with no cracking

I laid a flagstone floor with massive 15mm joints. Most grouts crack at that width, but this stuff filled them solid. No shrinking or cracking at all.

Sarah B.

Water beading effect prevents mould growth

We use the 'Anthracite' colour in all our walk-in showers. The water beading effect is real—it literally repels the water so mould doesn't get a chance to grow.

M. Khan (Pro Installer)

Stands up to chemicals and constant immersion

Refurbished a small indoor pool using the 'Moon White'. It stands up to the chemicals and constant immersion brilliantly. Hard to find a grout this reliable.

Blue Water Pools

Emulsifies really well without acid wash

I'm a DIYer and I was worried about grout haze. This emulsifies really well when you wash it off, leaving the tiles clean without needing acid wash later.

Jenny T.

Warm, subtle colour for kitchen tiles

Used the Jasmine shade for some cream kitchen tiles. It's a warm, subtle colour that looks much better than standard beige.

Robert E.

1-hour pot life without stiffening

The 1-hour pot life gives you time to grout a good sized wall without rushing. It doesn't go stiff in the bucket halfway through.

L. Davies

Stays in the joint on vertical work

Used it on wall tiles with 3mm spacers. It stays in the joint and doesn't slide down the face of the tile. Makes vertical work much cleaner.

City Tilers

Perfect colour match for silicone

The 'Manhattan Grey' is a spot-on match for the silicone I bought. Finishes the bathroom off perfectly.

Alice W.

Consistent shade across all bags

Bought 10 bags of 'Chocolate' for a large patio. Every bag was exactly the same shade. No patching issues.

G. Harris

Hard, durable, and professional quality

My clients are always happy with the result. It dries hard and durable, not powdery like cheap alternatives. It's the only grout I stock in the van.
