Product information

Product information

A washable, slate garage floor paint in a satin finish. Covers up to 12 m² per litre and dries in 72 hours.

  • Guarantee - Statutory
  • Suitable for use on Concrete surfaces
  • Surface Preparation - Open all your doors and windows to ensure the best ventilation. Move everything out of your garage, you’ll need to get into every nook and cranny. Clean up any oil and grease stains (oven cleaner and some vigorous scrubbing may work, otherwise call in a professional or use Thompson’s Oil and Drive Cleaner). How to prepare bare garage floors for painting - Newly laid concrete needs to be left alone to set for a month before you can paint it. Use a wire brush to clean the floor and remove dust and dirt. Concrete floors can react to the paint and crack or blister so seal the floor first with a stabilising solution. Or you can dilute the paint with 10% water. How to prepare previously painted garage floors - Clean the floor with a wire brush to dislodge dust and dirt. Wipe it down with white spirit.
  • Instructions for Use - Use a large brush, roller or pad to apply the paint. Give the paint a thorough stir. Start at the far end of the garage and paint towards the door. Work in small sections and remember to not paint yourself into a corner! For the best coverage, you’ll need to apply two or three coats. Leave four to six hours between coats for the best effect. The floor will be hardest after 72 hours. That’s when you can start moving your car and things back into the garage. To clean your equipment, simply wash it in warm soapy water.
  • Instructions for Storage - Protect from frost

Chris112233 - 5 / 5 - 06/06/2026

Great easy to use product & is a nice colour

This is the 2nd tin that I have bought to finish off painting a shed floor, being used to seal off the concrete & eliminate/minimise any dust.

Rob5 - 5 / 5 - 01/06/2026

This product is really good.

Used this for the first time the coverage and durability and consistency of this paint has given a good finish it does what it says in the tin.

Nblu - 5 / 5 - 27/05/2026

Does what it says on tin

Was a bit sceptical as is a water based product, but covers well and feels durable but only time will tell. Good points are virtually no odour and covers in one coat (but put 2 for durability. Bit pricy though!

Bev - 5 / 5 - 13/05/2026

Product great!
