Asphalt driveways - Winter delivers the perfect mix of conditions to cause potholes, pits and cracks in asphalt surfaces. While you may need professionals to pour new asphalt, repairing existing asphalt is well within the abilities of most DIYers. For pothole repairs, start by sweeping and removing any loose materials from the area needing repair. One product to use is U.S. Cold Patch by Sakrete in the trouble spot. Spread evenly to a depth of no more than two inches at a time. Use the back side of a shovel to compact the material; then, because there is no oily tracking with this material, just drive over it a few times with your vehicle. The compaction causes the product to cure into an effective patch. For deeper potholes, keep repeating in two inch amounts until completely filled.
Patios and pavers - Patio pavers and bricks can shift, sink or raise, and even crack during a tough winter. If your patio has a sand underlay, fixing problems can be relatively easy. For broken or cracked pavers, remove the damaged pieces, check that the sand is level, and fill the gap with a new paver or brick. If your patio has become uneven over time, you will need to lift all the uneven pavers, level the sand beneath - you may have to add sand - and then put the pavers back atop the now-level sand.
Concrete surfaces - Concrete driveways, walkways and steps can all succumb to cracking, crumbling, chipping and spalling after a harsh winter. To repair cracks of virtually any size, you can apply a product like Sakrete Top’n Bond. However, it is best to first power wash cracks to remove debris. For larger fissures, it may be necessary to use a hammer and chisel to remove crumbling concrete and produce a clean, clearly delineated repair site. For resurfacing old, damaged or spalled concrete, Flo-Coat resurfacing material by Sakrete is another product to consider. When using the latter, remove loose materials from the surface, mix the material, dampen the concrete surface with water and pour the resurfacing material onto the concrete slab. Use a long-handled squeegee to spread the mixture evenly. Be sure to protect expansion and control joints with tape to prevent filling.
Retaining walls - If the bricks or stones have remained secure and in good position, use a hammer and chisel to remove any cracked mortar to a little more than half the depth of the stone or brick, taking care not to damage the bricks. Then fill the gap with new mortar. To replace cracked bricks in ornamental walls, remove the damaged brick and the mortar around it, then remortar and replace with a new brick.
