This would mean any graffiti could be removed with soapy water when desired.

Also is the concrete newly laid?


Hi the window ledges in our house are made from concrete blocks, they have been painted but the paint keeps cracking and flaking, do you have a suitable sealant that can be applied on top of the paint that will add extra protection . . .

best paint to paint old slabs

Assuming these are bare, exterior patio type paving slabs, then after cleaning we would suggest Coo-Var Anti-Slip Acrylic Floor Paint. We have also added a new category for paving and patio slab paints.


I’m painting my drive with tarmacoat which I’ve order two 5 litre cans from yourselves, awaiting delivery. My drive is concrete paving slabs which were previously painted with tarmacoat and it was two years ago since it was pai . . .

Watering down the Tarmacoat is only for a primer coat on Asphalt.

For Concrete we would suggest testing if the substrate is porous or not prior to application.

For concrete surfaces which are porous and/or have loose particles or powdering, first prime with Rust-Oleum Mathys Primer 44 HS or Rust-Oleum 5220 Epoxyshield Sealer.

For non porous concrete prime with diluted Rust-Oleum Mathys Noxyde.

As the previous application has been applied incorrectly we would recommend removal of the paint back to bare concrete prior to application.


Can I use this to repair a concrete post that has started to break up at the top exposing the reinforcing rods . . .

Is it safe to paint electric storage heaters?

Blackfriar Quick Drying Radiator Paint will take a temperature up to 150°C and is available in a white semi-gloss finish. As we don’t know what actual surface temperature the storage heater will get up to we can’t say for sure if the paint will be OK on any particular storage heater, it could depend on the model, type etc. You will need to check with the manufacturer to find out what the surface temperature of their particular heater will get to during use. If it is below 150°C then Blackfriar Quick Drying Radiator Paint could be used.

Hi, We have a 14,000sq ft unit which needs its floor paint, the concrete floor is not perfect, but isn't awful. There are some minor dips which we are looking for a paint to cover the floor and maybe fill in some 1-4mm small dips. . . .

For the expected level of traffic you would need to consider an epoxy floor paint.

For application of these it would require the floor to be ground prior to application, during this process the dips could be addressed.  

Once this is done, the bare concrete floor is clean, dry, sound and prepared as detailed in the technical data sheet you could consider 2 coats of  304 HB Epoxy Floor Coating.

This is available in a range of colours in a gloss finish.

For 1301m² you would require approximately 781kg.
