Surface preparation

Apply using a brush to mark lines, designate safety areas or highlight step edges. 
This versatile paint can also be applied by roller to cover larger areas, although two coats would be required for depth of colour. 
Remove grease and oil using Watco Bio D.  This can also be used to remove grease from existing paint.
If overcoating existing paint, please ensure it is well bonded. Lightly sand any smooth, glossy paint to provide a key.
Make sure the surface is clean and dust free before continuing.
If using the paint over larger areas of new concrete, it should be at least 2 months old and Watco Basics Acid Etcher used to reduce alkalinity.
Such areas of concrete should be sufficiently porous to allow the paint to penetrate and ‘key’.


Holes in excess of 5mm deep can be filled with Watco Basics Floor Repair Mortar, or providing the floor is reasonably level, Watco Pourable Repair Mortar
For repairs which need to be ‘feather edged’ to nothing, or for repairs to damaged joint edges, please refer to Watco Concrex epoxy resin repair mortar.  This should also be used if repairing broken kerb edges or step nosings.  


Do not use if the floor temperature is below 10°C.
The surface must be dry. 
Stir the paint thoroughly. 
If using the Anti Slip Hazard Marking Paint, add the whole tin of aggregate to the 5L paint size, or half the tin to the 2.5L.
Stir the aggregate thoroughly into the paint. 
If applying with a roller, use the roller to work the paint into the surface of bare concrete. Two coats will be required.
If applying by brush, or for cutting in around edges, one coat is usually enough, but on rough or very porous surfaces a second coat may be required. 
Do not apply thickly.
