Floor paint

Really good product, no problems with paint

Gavin Watson (Glasgow, GB)
Light grey floor paint

Great stuff. Bought primer and sealer and clear coated the floor before putting two coats of light grey down. Floor was new and cast in January. Took 20l per coat and should have ordered 40l at the one time to ensure batch colour. There was a difference in colour between the two tins when delivered separately, but because each tin did a coat, it wasn’t an issue. That was my mistake but really pleased with the product, place looks great and because of correct prep and primer will last for a while.

Not used it yet! Too cold.

As above

Michael Drakard (Belford, GB)
Right product right result!

Tried cheaper product with pathetic results - wire brushed it off and got it right with premium paints concrete primer and floor sealer, fab results.

James Wallbank (Sheffield, GB)
Great Paint, Hard Wearing, Bright.

Spent extra getting this paint in blue, and I'm so glad I did. 75m² of basement workshop now looks FABULOUS, and the bright colour gives it a really professional look. (My lasers are red!) I've painted plenty of workshops grey, but, trust me, pay extra to go bright in an underground space—otherwise the whole thing will just feel boring.

The paint itself is excellent and hard wearing—spirit based is much tougher than water based—do dilute down the first coat (after the sealant) with 20% white spirit. Particularly in an enclosed space, USE A VOC MASK. The GVS ones are comfortable and seal well, and you can't smell the fumes. Run fans for 24 hours after if you don't want the rest of the building to smell.

Chritopher Ward (Ashington, GB)

Excellent product, rapid delivery.
Will be ordering garage floor paint as a follow up
