How to Winterize Outdoor Concrete

Concrete is porous, which is exactly why it takes stain so beautifully — and exactly why winter is hard on it. Water soaks in, freezes, and expands. A bottle of water in the freezer has crinkled sides so it can expand without bursting; concrete has no such option, so the pressure cracks it from the inside. Five things to do before the temperature drops.

Preparing outdoor concrete for winter.

1 · Patch and repair

Fix cracks and broken patches now, while you still can. A patching compound handles small cracks and tack holes; larger areas take patching compound combined with a cement-based overlay. Every crack you leave is somewhere water will get in and freeze.

Repairing concrete cracks before winter.

2 · Reseal — early autumn is the moment

Sealing is the actual defence. A penetrating sealer sinks in and fills the pores so water cannot, creating a non-porous surface rather than a film on top.

Water-based sealer

Only above 60°F / 16°C

Solvent-based sealer

Usable right down to freezing, 32°F / 0°C

Timing

Early autumn — before the first freeze, while temperatures still allow it

Sealing concrete floors ahead of winter.

3 · Cover outdoor countertops

Seal them, then cover them anyway. Tarps or heavy plastic, securely fastened — especially where there are sinks, cooktops or any other cut in the concrete, since those edges are where water gets in.

Covering outdoor furniture for the season.

4 · Bring portable decor inside

Statues, garden gnomes, movable fountains and birdbaths all come in — garage or shed. Turn them into temporary indoor decor, or put them somewhere covered. If they genuinely must stay out, wrap them securely in heavy plastic.

5 · Prepare what you cannot move

Drain completely

Large or built-in fountains and birdbaths

Remove and clean the pump

Then apply sealer

Invert the bowls

And cover with securely tied tarps

Cannot invert?

Fill the bowl with towels or other absorbent material first

Birdbath alternative

An electric heater keeps the water from freezing — no ice damage, and a rare winter water source for the birds

Spring will be back soon.
