Our cheapest two part epoxy floor primer
Watco Basics Concrete Floor Primer 5L is a highly effective penetrative epoxy resin, which provides a sound, solid base when painting porous, dusty concrete. Being water based it can be applied to a damp substrate if the floor has been washed as part of the preparation, so speeding up the painting process. It is primarily designed for use under Watco Basics Epoxy Resin Floor Paint but is an ideal primer for use under any water based epoxy resin paint. Water based epoxy resin paints can be applied quickly to this primer. Other types of paint, solvent based or 100% solids epoxy can be used, but the primer should be left for at least 48 hours for all of the water to evaporate.

Clean and prepare bare concrete using Watco Basics Acid Etcher.This will remove light grease and oil deposits.
To remove heavier grease and oil use Watco Basics Floor Cleaner.This can also be used to remove grease from existing paint.
Make sure the surface is clean before continuing.
New concrete should be at least 2 months old.
This primer is water-based, so it doesn’t matter if the floor is slightly damp after cleaning.
Holes in excess of 5mm deep can be filled with Watco Basics Floor Repair Mortar, or providing the floor is 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.
Check the air temperature is around a minimum of 15°C and the floor temperature at least 10°C.
Stir the contents of the resin and curing agent tins individually, and then empty the contents of the resin into the curing agent tin.
Mix the two components thoroughly using a wide bladed tool such as a piece of batten. A paint mixer in an electric drill is ideal.
Tip the contents into a paint tray and apply using a medium pile roller. A brush can be used to cut in around edges.
Now it is mixed you have up to 2 hours to apply it before it become unusable.
Do not apply thickly, but work it into the concrete surface using the roller.
Important: The performance of water-based paint is affected by poor ventilation, damp and low temperatures. The drying times quoted above will extend in any of these conditions.
Do not apply if the floor temperature is below 10°C.
Not recommended (and not necessary for) smooth, dense, non-porous or painted surfaces - instead see Watco Powerfloat Primer.
Do not use in confined spaces with little or no ventilation since it won’t dry. Watco 4 Hour Epoxy Primer is suitable for these conditions.
