Wanna learn how to Repair & Resurface Driveways? Nearly all driveways will develop cracks at some time or other. The causes can be numerous. One is tree roots growing beneath the pad and another is the freeze-thaw cycle. This can expand and contract concrete by 9%. Instead of having pour a brand new slab, why not just repair the driveway cracks with a little SANI-TRED® sealer?
Preparation to remove all the mold, mildew, and ground in dirt is the single most important factor in preparing concrete. This will ensure a nice and clean start for your DIY driveway crack repair. To prepare concrete acid etching and pressure watching is the best option. This is accomplished by mixing “Muriatic Acid” and water. Muriatic Acid is commonly found at most larger hardware stores, paint supply stores, lumber companies, swimming pool supply stores, Wal-Mart, Kmart, etc.
See our advanced instructions for how to acid etch concrete.
Take extra time to clean out all the cracks and crevices you may see. NO MATTER how small or thin. You want your concrete patching to have a good surface to adhere to.
Once the concrete is completely dry, prime the concrete with 1 coat of PermaFlex™ (240 sq ft per gal) using a roller or squeegee. This coat of PermaFlex™ will act as a binder within the substrate. PermaFlex can be thinned using either Xylene (in states where allowed) or Acetone to encourage even more rapid and deeper absorption/penetration.
Patch and profile any joints, seams, cracks, holes and rough areas using LRB/TAV™ mixture. 2-parts LRB is mixed with 1-part TAV™ to create the thickest mixture possible (similar in viscosity as silicone caulk). Wall/floor junctions require a 1” diameter caulk bead of LRB/TAV™ mixture and most other cracks & joints use a 3/4” diameter caulk bead.
After applying basecoat and patching cracks with LRB apply a topcoat of PermaFlex® (240 sq ft per gal). If you are looking for a decorative surface you can achieve the look of granite with our Graniflex™ system.
Your DIY concrete driveway resurfacing and repair should be able to handle foot traffic within 6 hours of adding the texture to it. Give it about 24 hours before driving your car onto it. This does a really good job of patching without having to bust up everything and deal with the mess and also suffer the costs of putting in a whole new driveway.
