Indoor coatings for basements, cold rooms and mechanical rooms

Basements, cold rooms, laundry and mechanical rooms deal with moisture moving through the slab, dust and everyday wear that plain concrete can't handle long-term. Our indoor coatings create a smooth, easy-to-clean surface, and where needed a moisture-mitigation primer manages vapour before the coating goes down.

Why homeowners choose us for basement floor coatings

We test slab moisture, repair cracks and joints, and specify the right primer and system for below-grade conditions, so the finished floor stays bonded, seamless and easy to maintain.

FAQ

Will a basement floor coating smell?

Odour depends heavily on the chemistry. Some products carry a noticeable smell during application and for a period after; others are formulated to be lower-odour. In an occupied home we look at the product's data for odour and ventilation requirements, plan airflow, and agree timing with you — for example, whether anyone sensitive to odours should be out of the house for part of the day.

Why test for moisture before coating a basement?

A basement slab sits in contact with the ground, and moisture can move up through it even when the surface looks dry. A coating sealed over that moisture can trap it, and the pressure can push the coating off as blisters or peeling. Testing — commonly by in-situ relative humidity under ASTM F2170, or by the calcium chloride method under ASTM F1869 — tells us whether the slab is within the limit the chosen product allows. If it isn't, a moisture-mitigating primer can be specified where the manufacturer supports it.

Can you coat a basement floor in winter?

Heated basements are often the best winter work there is, because conditions are stable. What matters is holding the slab and air temperature within the product's range and above the dew point through the whole cure, and managing ventilation while people are living upstairs. We check conditions on the day and test the slab for moisture before we start, because basements carry moisture risks that garages don't.

What is hydrostatic pressure?

Hydrostatic pressure refers to water pressure pushing against the concrete slab from beneath or surrounding areas. Excessive moisture pressure can damage flooring systems if not properly controlled.

Does waterproofing help prevent mold and mildew?

Yes. By reducing moisture intrusion and controlling damp conditions, waterproofing systems help minimize the environmental conditions that contribute to mold and mildew growth.
