Watco Concrex Coving Mortar
- Lightwork of heavy-duty repairs
- Structural strength solutions
Watco Concrex Coving Mortar is a dark grey epoxy mortar for forming a rounded skirting where the floor meets the wall. The curved profile replaces the sharp internal corner where dirt can collect, giving cleaning tools a continuous surface to follow.
Use it to form coved skirting in laboratories, cleanrooms, hospitals, food halls and bund areas. Its lightweight, fine-textured mix can be shaped with a coving trowel and feathered along the top and floor edges. The cured mortar is non-dusting and can be left exposed or painted with a compatible coating.
Surface Preparation
Prepare a strip at least 100mm high on the wall and 100mm wide on the adjoining floor. Remove dust, loose material, oil and grease. The prepared surfaces should be sound and dry.
Apply Watco Tack Coat along the run, taking the primer at least 80mm up the base of the wall. Follow the primer’s instructions and apply the mortar while the Tack Coat is still tacky.
Technical Data
- Two-part epoxy mortar, dark grey.
- Approximate yield is 5 linear metres per 5kg at a 50mm × 50mm cove profile.
- Typical curing times are 120 minutes at 10°C, 80 minutes at 15°C and 60 minutes at 25°C.
- Suitable for interior and exterior use on concrete, sand and cement, and metal.
- Store between 10°C and 30°C for about eight hours before use. Protect from freezing.
Directions for Use
Mix the full pack on a mixing board or tray. Add the curing agent to the resin and aggregate blend and mix until the colour is even. Wear the protective equipment specified in the safety sheets. Set out the run and have the coving trowel ready before mixing.
Press the mortar firmly onto the tacky primer, then draw the coving trowel along the junction to form the radius. Feather the upper and lower edges to leave a neat transition. Where the run crosses an expansion joint, follow Watco’s instructions for cutting through the cured mortar along the joint.
Limitations
Allow at least 12 hours at 15°C or above before applying a suitable water-based or solvent-free epoxy coating. Wait at least seven days before applying solvent-based paint. Avoid steam cleaning and temperatures above 60°C. Remove food products during application and cure.
Product FAQs
How much skirting will one pack make?
A 5kg pack makes approximately 5 metres of skirting at a 50mm × 50mm profile. Larger coves will use more mortar.
Is Tack Coat required?
Yes. Apply Watco Tack Coat to the prepared junction and shape the mortar while the primer is still tacky.
Can the cove be painted?
Yes. Allow at least 12 hours at 15°C or above for a compatible water-based or solvent-free epoxy coating, or seven days for solvent-based paint.
What tool forms the curve?
Use a coving trowel to shape the radius and feather the edges into the adjacent wall and floor.
