Decorative Concrete Sealing in St. Thomas
Stained, coloured and exposed aggregate concrete around St. Thomas represents real design investment, and All-Seal's decorative concrete sealing in St. Thomas is built to protect that finish rather than flatten it. We use breathable sealers on decorative surfaces in St. Thomas that enhance colour depth and guard against the cloudy whitening a wrong sealer can cause. If you have decorative concrete in St. Thomas that has never been sealed, or has an old coating that has yellowed, a free inspection will tell you exactly what it needs.
Recommended finish
Semi-Gloss
Semi-Gloss brings out colour depth on stained and coloured concrete without the extreme shine that can look artificial on a decorative, textured finish.
St. Thomas's elevation and proximity to the Lake Erie shoreline mean concrete here experiences more humid, muggy stretches in July and August than towns further inland, which affects how long a sealer takes to cure properly before rain.
What's included
Decorative Concrete Sealing done properly in St. Thomas
Coloured, stained and exposed aggregate concrete represents real investment in how your property looks. All-Seal seals decorative concrete with breathable sealers that deepen colour and protect the finish without trapping moisture underneath.
- 1
On-site inspection
We examine the specific decorative finish, whether stained, coloured or exposed aggregate, and note any fading or wear before quoting.
- 2
Pressure washing
The surface is carefully pressure washed to lift dirt and buildup from the finish without disturbing the decorative texture underneath.
- 3
Crack and joint repair
Any cracks are repaired first, matched as closely as possible to the surrounding finish so the repair blends rather than stands out.
- 4
Full drying period
Decorative surfaces are left to dry completely, since a breathable sealer needs a dry substrate to bond and perform correctly.
- 5
Sealer application
We apply a breathable sealer chosen for the specific decorative finish, whether that means enhancing colour on stained concrete or protecting exposed aggregate texture.

FAQ
Decorative Concrete Sealing in St. Thomas

Call 519-266-6796What does decorative concrete sealing cost in St. Thomas?
Every quote is per property, based on square footage, the type of concrete and whether it was sealed before. The inspection in St. Thomas is free and the written quote includes the recommended sheen.
Will sealing change the colour of my stained concrete?
A quality sealer typically enhances and deepens existing colour rather than changing it, bringing out richness in stained or coloured concrete that is harder to see when the surface is dry and unsealed.
What is blushing and how do you avoid it?
Blushing is a cloudy, milky-white appearance that happens when moisture vapour gets trapped under a non-breathable sealer. We use breathable sealers matched to decorative concrete specifically to avoid this issue.
Can you seal exposed aggregate concrete?
Yes. We use sealers and application methods suited to exposed aggregate that protect the surrounding matrix and exposed stone from staining and UV fading without dulling the texture.
Do you charge extra to come to St. Thomas?
No. St. Thomas is inside our regular service area and inspections there are free.
