What's the best concrete finish for a garage floor in Fredericton that won't become slippery when wet from snow and slush tracked in?

For a Fredericton garage floor, a broom finish is the best choice for traction when wet, followed by a penetrating sealer to protect against salt damage from tracked-in snow and slush.

A broom finish creates hundreds of tiny ridges across the concrete surface that provide excellent grip even when wet. After the concrete is floated and initial finishing is complete, a stiff-bristled broom is dragged across the surface in straight lines or a slight arc pattern. This texture is aggressive enough to prevent slipping on wet concrete but not so rough that it's difficult to clean or uncomfortable to walk on. The grooves also help channel water and slush toward the garage door rather than letting it pool on the surface.

Avoid smooth troweled finishes in NB garages — they become dangerously slippery when wet and offer no texture for traction. Stamped concrete, while attractive, can also become slippery and the recessed areas collect salt and debris that's difficult to clean out.

Sealing is critical for any Fredericton garage floor. From November through April, vehicles track in road salt, sand, and corrosive slush that will gradually deteriorate unsealed concrete. Apply a penetrating silane/siloxane sealer ($40-$80 per gallon) about 30 days after the concrete is poured, once it's fully cured. This type of sealer soaks into the concrete and repels water and salt without changing the appearance or creating a slippery film on the surface. Reapply every 2-3 years.

Proper concrete specifications matter in Fredericton's freeze-thaw climate. Use air-entrained concrete (25-32 MPa with 4-7% air content) even for garage floors. While garages are enclosed, they're typically unheated and the overhead door allows cold air infiltration. The concrete will still experience freeze-thaw cycles, especially near the door opening where snow and slush accumulate. Standard concrete without air entrainment will develop surface scaling and spalling within 5-10 years.

Thickness and reinforcement should be 4-5 inches with welded wire mesh (6x6 W1.4) supported on chairs at mid-slab height. Include control joints every 12-15 feet to control where shrinkage cracks occur. Ensure proper drainage — the floor should slope slightly (1/4 inch per foot) toward the garage door so water and melted snow drain out rather than pooling inside.

Professional installation recommended for garage floors. A typical two-car garage floor (400-500 square feet) costs $3,000-$5,000 installed in the Fredericton area. The concrete must be placed, screeded, floated, and broom finished within a narrow time window, and mistakes are permanent and highly visible in this high-use space.
