Watco Concrex gives superior strength and durability to any repair due to its unique resin rich formulation. We know our customers are going to put it to the test with constant heavy traffic, so our formula includes an epoxy novolac resin blend - the expensive component that binds the material and gives it its industrial toughness. We haven’t just thought about the resin though. Every component in the Concrex formula has been chosen to achieve unrivalled strength. We’ve used several sand particle sizes that interlock together for a stronger bond and a smoother finish. This combination means that you can carry out repairs down to a feather edge without the need for a primer.
We recommend using Watco Tack Coat for intricate repairs or high-impact areas such as broken expansion joint edges, step nosings or when applied as a thin screed (5mm thick) for resurfacing. Using Tack Coat in these situations not only ensures complete adhesion, but it makes it easier for you to get a professional finish.
For over 50 years, Concrex has been the leading epoxy repair mortar and millions of kilos of it are reinforcing and protecting concrete floors, steps and ramps across Europe and the rest of the world. It should be regarded as permanent, which is why we consider it the benchmark for repairing concrete. It’s a versatile formula that results in a granite-hard finish that is impervious and non-dusting. After all, it’s what you should expect from our top performing repair mortar.

The surface must be clean, dry and free from loose material. Sweeping the area with a broom or wire brush is usually enough to remove any dust and dirt. If the area is contaminated with oil or grease, we recommend using Watco Bio-D to clean the damaged surface. Bio-D is an industrial degreaser that is tough on oil and grease, but easy for the environment. It's biodegradable, low odour and can easily be washed away without harming the surrounding concrete or drainage systems nearby.
To ensure maximum adhesion, we recommend using Watco Tack Coat with all applications. However, this is especially important for shallow repairs and screeding. The surface will need to be dry, or slightly damp before applying. If used on areas that are extremely wet, or where water is pooling, the water will dilute the primer and you won’t get the same strength properties.
Each bucket contains a part-mix of Concrex powder, sand and epoxy resin and bottles of curing agent. Empty the mixture into a Watco Concrex Mixing Tub. Create a well in the middle, then pour in the curing agent into the middle, ensuring all the bottles are completely empty.
Wearing rubber gloves, mix the components together by hand, or use a Mix & Apply Trowel until you get an evenly coloured grey mixture. We've made it easy by adding the grey colour to the curing agent, so you'll know when it's thoroughly mixed. For large quantities, we recommend using a mixer to save you time.
Apply the mixed mortar to the damaged area, either by hand or trowel. Slightly overfill the hole then use a 10" Steel Float to compress the mortar into the hole. If you wipe the trowel with White Spirit, it will help you get a professionally smooth finish and avoid the mortar from sticking.
