Quick and easy concrete floor repair mortar
Watco Basics Pourable Repair Mortar is a quick and easy way to fill holes in concrete floors. This blended polymer and cement formulation is strong enough to resist heavy foot traffic, trolleys and trucks; (for areas where there is regular forklift traffic, we recommend Watco Flowpatch). Just take as much powder as you need out of the bucket, mix with water and pour – you don’t need a primer.
The mortar will not shrink as it dries and will take foot traffic after only 4 hours and trucks and trolleys after 6-8 hours. The product ‘flows’ to fill the hole making it unsuitable for ramps, steps or broken concrete edges; please select Watco Concrex (epoxy repair mortar) for this type of repair.

Only basic preparation is necessary. If the hole or patch to be repaired is just dirty and dusty, give it a good sweep. Floor Cleaner can be used to remove oil and grease, or grease and loose material can be removed from small patches using a stiff broom or wire brush.
It does not matter if the floor has been left damp following any wet preparation.
Dampen dusty, porous surfaces with water in hot, dry conditions.
The mortar can be applied at any thickness between 5mm and 100mm. For deeper holes build up in layers, allowing the first layer of 100mm to dry for 12 hours.
If the edge of the repair is less than 5mm deep, chip some concrete away so that the edge of the mortar repair will be 5mm thick. For feather edge repairs which go to nothing please see Watco Concrex (epoxy resin mortar).
Remove the bag of powder from the Pourable Repair Mortar bucket.
The mix is 1 part water to 3 parts powder.
Only mix as much as you can use in 15 minutes. A cup can be used to measure the parts of water and powder.
Put the water into the plastic bucket.
Gradually add the powder mixing continuously. We recommend a mixing blade fitted into an electric drill. The ratio of water to powder is not critical, you just want the mix to be a consistency which can be poured. If it looks too runny add more powder, or too stiff, more water.
Once you’ve stopped mixing and started using the product do not re-mix it. Immediately pour into the hole using a trowel to ‘help’ smooth the mortar into place.
Not recommended on slopes, steps or broken concrete edges.
Resists oils and grease but not chemicals (see Watco Concrex).
