Repair Concrete Scaling

Repair concrete scaling to improve appearance, prevent further damage, or in preparation for stains, paints, or overlays.

Concrete scaling is a common problem especially in harsh climates with many freeze and thaw cycles within a given year. When water penetrates a weak, porous surface, it freezes and expands breaking apart the surface. There are many factors that contribute to concrete's susceptibility to scaling such as improper finishing methods or using deicers that contain salt.

Repairs

Brush away all loose debris and concrete chips. Use a pressure washer if available. Clean the area thoroughly with water and use cleaners to get rid of oil and grease or anything that may inhibit bonding. Let it dry.

Choose a resurfacing material that contains a bonding agent. Look for the words "latex, vinyl, or polymer" on the label. Mix up a batch according to the labeled instructions and pour it over the scaled area. Then smooth it out with a steel concrete trowell and remove any excess. Smooth it two or three times but don't overwork it. For driveways, patios, sidewalks or any surface with a broomed finish, drag a broom or brush across the patched area when it begins to harden to help match the surrounding concrete. You will never completely match any repaired areas with the rest of the concrete. If you're resurfacing a smooth floor such as a basement or garage, furthur smoothing can be done later with a grinder or sandpaper.

Tips

• Repair concrete scaling when the temperature is 50 degrees and above and overnight temperatures won't drop below freezing over the following week.
• Keep foot traffic off for at least 36 hours and vehicle traffic for at least a week.
• Make sure resurfacing material contains cement or cementitious material if you plan to acid stain later.
• Apply concrete sealer after resurfacing has hardened and once a year in the fall if you live in a harsh climate.
• Use deicers that don't contain any calcium or sodium chloride.
