Winterizing Concrete with DriveHard
Winter is upon us, so it’s time to winterize your concrete! When rain, snow or ice settles into the cracks of concrete and/or saturates the substrate, concrete will shift and move every time freezing and thawing occurs. This reoccurring movement can make the cracks expand (when water freezes it can expand about 9%) or it can create brand new cracks. This can potentially be very harmful to concrete surfaces, especially when left unprotected. Concrete is like a sponge, and if left unprotected, will retain moisture during the winter. Also, when the temperature drops below 0 °C or 32 °F (freezing), the water within the concrete expands and can cause the surface to flake or spall. That is why winterizing concrete is essential to maintain concrete to prevent cracking, spalling, flaking or other issues.
One way to help prevent these damages from occurring is using NewLook’s DriveHard™. DriveHard™ & DriveHard™ Pro are premium concrete and masonry weatherproofers and fortifiers. The concrete sealer penetrates deep into the surface to create a chemical bond that helps prevent damage from many common problems, including repeated freeze-thaw cycles. The patent-pending formulas create a breathable, durable and water-repellent concrete surface. DriveHard™ & DriveHard™ Pro leave a natural-looking finish that does not create a film or change the surface texture or color.
How to Apply DriveHard™
- Use NewLook’s DriveHard™ to weatherproof and protect the concrete surface from freeze/thaw issues
- Clean the surface with a pressure washer and clean with NewLook’s 3-in-1 Prep to remove all dirt, oil, debris and other contaminants that can inhibit the sealer from bonding
- Apply DriveHard™ evenly across the surface in two light coats with a HVLP sprayer, pump sprayer or roller
However, if the damage has already occurred, there are a few things that can be done to help prevent these wintertime issues in the future.
Tips on How to Repair Cracks & Damaged Concrete
- Use a cementitious or flexible polyurethane sealant that allows the concrete to move and shift without damaging the substrate.
- Widen the existing crack with a hammer and chisel to a minimum of a 1/4 of an inch. Clean any debris from the crack with a brush.
- Fill the crack with the sealant with a caulking gun and level to the surface or fill with a cementitious filler and level with a spackle knife or trowel.
- Resurfacing the concrete with an overlay can fix all prior damages of the surface and make it appear like new.
- Once the overlay has been applied, protect the substrate with DriveHard™ to help prevent any further damage.
