Brick-red stamped concrete patio restored with a gloss sealer behind a home in London, Ontario

Patio sealing

Patio sealing that brings the colour back and keeps it there.

Stamped, broom-finish or coloured patios cleaned, prepped and sealed with a solvent-based sealer that resists sun, rain, spilled wine and barbecue grease. Choose matte, semi-gloss or gloss.

How we seal a patio

  • Deep clean

    Pressure washing lifts algae, pollen, leaf stains and the grey film that builds up on unsealed concrete.

  • Furniture and planters moved

    We clear the surface, seal underneath and put everything back once it can take foot traffic.

  • Edges and steps masked

    Siding, stone borders and garden beds protected before we spray.

  • Solvent-based sealer, sprayed and rolled

    Even coverage with no lap marks, including the textured joints of stamped patterns.

  • Non-slip additive where it matters

    Standard on pool surrounds and steps, optional anywhere else.

  • Ready for the weekend

    Foot traffic the next day; furniture back after 48 hours.

Patio problems sealing solves

☀️

Faded colour

UV bleaches integral and stained colour. A solvent-based sealer restores and locks it in.

🍷

Food and drink stains

Sealed concrete wipes clean; unsealed concrete drinks the spill.

🌿

Algae and moss

A sealed surface dries fast and gives growth nothing to grip.

❄️

Winter scaling

Keeps meltwater out of the surface so it doesn't flake in spring.

Recommended finish

Gloss for patio sealing

Gloss gives stamped patios the wet look most clients want. Semi-gloss is the choice if you prefer a softer satin sheen.

All three finishes use the same high-quality solvent-based sealer. Sheen is the only difference, and we bring samples to every site assessment.

FAQ

Patio Sealing questions

Still wondering about something? Email us, or use the form and we will get back to you within 4 business hours.

Can you seal a patio that was sealed before?

Yes. If the old coat was solvent-based, our sealer re-emulsifies it and the coats become one. If it was water-based or is peeling, we strip or prep it first and explain the extra step in the quote.

Will the sealer make my patio slippery?

Gloss can be slick when wet on smooth stamped patterns. We add a non-slip additive on pool decks and steps and anywhere you ask for it, with no change to the look.

How soon can I use the patio?

Walk on it the next day, put furniture back after 48 hours.

What time of year is best?

Late spring through early fall, when the surface is dry and temperatures sit between roughly 10 and 30°C.
