Watco Epoxicote High Build Primer
Litres required: 0.00L
Based on 6.0 m² per litre- Lightwork of heavy-duty repairs
- Structural strength solutions
Watco Epoxicote High Build Primer prepares bare concrete before the Watco Epoxicote High Build floor coating system. Its water based, two part epoxy formulation helps seal porous concrete to reduce air-entrapment bubbles in the subsequent high build finish, while also providing adhesion on suitable hard, smooth concrete.
A porous unsealed floor can release air into a heavy resin coating during application and cure. Priming first helps control this and creates a more consistent base for the specified finish. The Light Grey primer is designed for interior use on bare, unsealed concrete, including suitable power floated surfaces. Use it as part of the named Epoxicote High Build system rather than as a general-purpose primer for unrelated paints.
- Seals porous concrete before a high build epoxy finish.
- Helps reduce air-entrapment bubbles.
- One coat, applied by roller.
Surface Preparation
Remove contamination, loose material and surface laitance. If Etch & Clean is used where appropriate, rinse thoroughly and allow to dry. Slight residual damp after cleaning is acceptable according to the application guidance, but concrete moisture must remain below 75% RH. New concrete should generally dry for four weeks in summer or six weeks in winter. Confirm the preparation needed for especially smooth or polished areas.

Coverage
Approximately 18m² per 3L for one coat (6m²/L). Work the material evenly into the concrete and keep within the specified maximum coverage so the primer provides a continuous base.
Directions for Use
- Stir each component separately, then empty the complete resin and curing agent into the outer container.
- Mix thoroughly with a wide bladed tool, scraping the sides and base until the colour and consistency are uniform. Mix one pack at a time.
- Apply with a medium pile roller, using a brush at edges, in warm conditions with good ventilation.
- At 20°C, allow approximately twelve hours before applying Watco Epoxicote High Build. The technical sheet gives twenty-four hours at 10°C; colder conditions slow drying.
Limitations
Use only with Watco Epoxicote High Build. Not suitable for bare metal; most self-levelling compounds require specific advice before painting. Do not treat the primer as a final wearing surface. Condition the product at 15–25°C for at least eight hours before application and protect from freezing. Clean tools with warm soapy water before the material cures.
