Learn moreThree finishes
Matte, semi-gloss or gloss. Same protection, your look.
Every job uses a high-quality solvent-based sealer that penetrates deeper, enhances colour more and recoats seamlessly. The only decision is how much sheen you want.
Low sheen
Matte
Protection you can't see.
A matte finish protects the concrete without changing how it looks. The surface stays natural, colour is lightly enriched, and there is no reflection in sunlight. It is the finish we recommend for broom-finish driveways, exposed aggregate and anywhere slip resistance matters more than shine.
Best for: Broom-finish driveways and garage pads · Exposed aggregate patios and walkways

Semi-Gloss
The sweet spot for stamped and coloured concrete.
Semi-gloss is the finish most of our clients choose. It brings out the colour and pattern of stamped, coloured and decorative concrete with a soft satin sheen that looks rich without looking wet. It shows less dust and dirt than gloss and is easier to keep looking even between reseals.
Best for: Stamped concrete patios and driveways · Coloured and integrally pigmented concrete

High sheen
Gloss
The showcase finish.
Gloss gives stamped and coloured concrete a permanent wet look with the deepest colour enhancement we can offer. It is the finish that makes a driveway or patio the focal point of the property, and the one most people picture when they think of freshly sealed stamped concrete.
Best for: Stamped patios and pool surrounds · Coloured and stained driveways

AfterWhy TriCity
The concrete sealing specialists of Southwestern Ontario.
Unsealed concrete is porous. It drinks road salt, oil, water and UV, and gives it all back as scaling, staining and faded colour. Sealing stops that cycle. Doing it with the right product and the right prep is what we do all day.
Solvent-based, not water-based
Our sealers penetrate deeper, enhance colour more and re-emulsify the previous coat at reseal time, so there is never a peeling layer between coats.
Three finishes
Matte, semi-gloss or gloss, chosen on site with samples in hand. Same protection in every case.
Prep is the job
Pressure washing, stain treatment and a dry, inspected slab before a drop of sealer goes down.
Sprayed and back-rolled
Even coverage into every stamped joint and around every stone, with no lap marks or streaks.
5-year workmanship warranty
Peeling, flaking or uneven coverage caused by our application is fixed at no charge. In writing.

“TriCity sealed our driveway last spring and it still looks brand new. Zero staining from our vehicles and it survived a brutal winter without a single crack. Absolutely worth it.”
“The crew was on time, professional, and the stamped concrete on our backyard patio looks incredible now. The colour really popped after sealing. Highly recommend them!”

service@tricityconcretesealing.caWhat is concrete sealing and why do I need it?
Concrete sealing is the process of applying a protective liquid coating to concrete surfaces. Without sealing, concrete is porous and absorbs water, oil, road salt, and other substances that cause staining, cracking, spalling, and fading. Sealing locks out these damaging elements, extends the life of your concrete by years, and keeps it looking like new.
How long does concrete sealing last?
Our premium sealers typically last 3–5 years depending on traffic, exposure to road salt, and environmental conditions. High-traffic driveways or areas subject to harsh winters may require resealing every 3 years. We back every application with a workmanship warranty, and we'll let you know when your concrete is due for a touch-up.
How long does the sealing process take?
Most residential driveways take 2–4 hours from surface preparation to final application. Larger areas like commercial parking lots or multi-surface projects may take a full day. We'll give you an exact time estimate during your free site assessment. The sealed surface is typically ready for foot traffic in 4–6 hours and vehicle traffic within 24 hours.
What is the difference between matte, semi-gloss and gloss finishes?
All three use the same high-quality solvent-based sealer; the difference is the sheen. Matte keeps a natural look with no reflection, semi-gloss adds a satin sheen and strong colour enhancement, and gloss gives a wet look with the deepest colour. Semi-gloss is our most popular choice for stamped concrete.
Why do you use solvent-based sealers instead of water-based?
Solvent-based acrylic sealers penetrate deeper, enhance colour more, and re-emulsify previous solvent-based coats so recoats bond seamlessly with no peeling layers. They also hold up better against road salt, UV and hot tires through Ontario winters and summers.
Can you make a sealed surface less slippery?
Yes. We can add a non-slip additive to any finish, which is standard for pool decks, steps and sloped walkways. It does not change the look of the finish.
