You can act now to keep your concrete surfaces looking great all year

(BPT) - With the weather turning colder, you may think there's not much more you can do to protect your outdoor surfaces from damage caused by the elements. The good news is, it's not too late to ensure that any unprotected patios, driveways, pool decks, paths, sidewalks or other exterior concrete surfaces on your property are safe from flaking, cracking, spalling or staining. Depending on the current climate conditions where you live, there still may be plenty of time for you to tackle this crucial outdoor project before the worst winter weather.

Why is concrete vulnerable to damage?

While you may think of concrete as a hard surface, it's actually more like a rigid sponge. If it's not properly sealed and waterproofed, concrete can become saturated from the moisture in rain, snow and ice. Then when temperatures drop under freezing (32 degrees Fahrenheit), the water that's saturating the concrete also freezes - and then can thaw and refreeze as temps fluctuate, causing visible damage.

Unprotected concrete surfaces on your property that looked so clean and smooth when first installed can become cracked and flake, as well as become stained and discolored by salt, leaves, dirt, oil and debris that accumulate over time.

How to protect your exterior surfaces

You can take simple steps to keep your outdoor concrete surfaces in top condition using QUIKRETE® Concrete & Masonry High Gloss Sealer, as long as the current air and surface temperatures are between 50 and 90 degrees Fahrenheit, and rain or heavy dew are not expected within 24 hours.

QUIKRETE Concrete & Masonry High Gloss Sealer is a water-based, acrylic clear sealer that's designed to waterproof, seal and enhance the color of decorative or standard gray concrete, pavers, masonry, brick or natural stone surfaces. It also repels oil, grease, acids, household chemicals, food stains and ultraviolet rays to further protect your surfaces.

Follow these steps to seal your concrete surfaces:

  • Before starting: Always wear eye protection and impervious gloves, such as nitrile gloves, before using the product.
  • For new concrete surfaces: Allow concrete to cure at least 30 days before applying the sealer.
  • For existing concrete surfaces: Repair any damage, cracking or flaking first, then clean thoroughly and allow to dry 24 hours before sealing. To eliminate oil, grease and other unwanted tough stains, use a solvent-free, low odor and low VOC cleaner, etcher and degreaser before sealing.
  • For previously sealed surfaces: Clean concrete thoroughly before applying.
  • When the concrete surface is ready: Simply apply sealer with a roller, brush or garden sprayer according to product instructions. Depending on the porosity of the concrete, one gallon of sealer uniformly applied should cover 200 to 400 square feet. A second coat of sealer can be applied after two hours. For best results, the second coat should be applied perpendicular to the first coat.

Looking for a less glossy, more natural-looking concrete surface? You can use QUIKRETE® Concrete & Masonry Waterproofing Sealer, following the same basic directions.
