Watco Powerfloat Sealer is a clear epoxy floor sealer designed for hard, smooth and power floated concrete indoors. Its two part, water based formulation seals and dustproofs suitable concrete while retaining the appearance of the underlying floor, with a choice of Gloss or Matt finish.
Dense concrete can be difficult to coat because ordinary penetrating sealers cannot soak into the surface. Powerfloat Sealer is formulated for this type of floor and can be applied directly after correct cleaning and preparation. It suits warehouse, workshop and industrial interiors where a clear, easy-clean finish is wanted. Watco recommends diamond grinding or shot blasting where practical for the best overall result, particularly on highly polished surfaces.
- Clear epoxy protection for smooth concrete indoors.
- Gloss and Matt finish options.
- Normally one coat, without a separate primer.
Surface Preparation
Allow new concrete at least twenty-eight days to dry. Remove oil, grease, dust, dirt and other contamination, leaving a clean, dry surface. Highly polished concrete may require mechanical abrasion. Confirm suitability for the actual floor before application; a small test area helps assess appearance and adhesion.
Technical Data
| Pack size | 5L |
|---|---|
| Finish | Clear Gloss or Clear Matt |
| Composition | Two part, water based epoxy |
| Application range | 15–30°C |
| Pot life | Up to 2 hours at 20°C; aim to apply within 1 hour |
| Shelf life | 24 months unopened |
Coverage
Approximately 40m² per 5L per coat (8m²/L). Spread a full mixed pack over a measured area of at least 40m² rather than applying it heavily. One coat is normally enough; very porous substrates can need a second coat for an even finish.
Directions for Use
- Stir the resin and curing agent separately, then empty both complete components into the outer tin.
- Mix thoroughly for two to three minutes with a wide bladed stirrer, scraping the sides and base. The mixed liquid initially appears white or off-white.
- Transfer to a roller tray. Apply evenly with a medium pile roller and brush at edges.
- Maintain a through draught and suitable temperature while curing. Allow approximately sixteen hours at 15–20°C before general traffic, with longer waiting in poorer conditions.
Limitations
Interior use only. Excessive thickness or inadequate ventilation can prevent the coating drying clear. Cold or damp conditions delay or prevent curing, so do not apply below 15°C or above 30°C. Not suitable for bare metal; seek advice before coating self-levelling compounds. Remove food from the area during application and cure. Store at 15–25°C for at least eight hours before use and protect from freezing.
Product FAQs
Can it seal smooth power floated concrete?
Yes, that is its intended application. The floor still needs cleaning and preparation; highly polished surfaces can require abrasion.
Does it need a primer?
Normally no. Follow the technical sheet and assess the actual substrate before coating.
Why does the mixed sealer look white?
The water based components initially appear opaque. Correct thickness, warmth and ventilation are important for the clear finish to develop.
How soon can traffic return?
Allow approximately sixteen hours at 15–20°C under suitable conditions. Cold or damp conditions can extend curing.
