Fast Setting Thin Concrete Patch Repair
Flash Patch is a cement based patching compound that can go from 1” thick to feather. Cures in 45 minutes with a no-slump, workable patch in white & gray cement.
Large Concrete Repair Patching Product
Deep Level is designed to go from 1/8” and up to fill larger holes and chunks of missing concrete. When patching concrete from 1”- 4” addition of pea gravel is recommended.
Nobody wants a concrete slab that has large pits and voids in it, no matter what their cause was. And you certainly can’t apply a nice new decorative overlay without filling them in first! Our concrete patching products allow you to deal with this step extremely efficiently and easily. We’ve formulated our pre-blended patching bag mixes to deal with a wide range of concrete problems.
When trying to level out your slab or deal with very large holes and voids, we’ve developed our Deep Level bag mix. In conjunction with an easy-to-use bonding agent, this product can help you save a slab that you may otherwise have needed to simply destroy and re-pour. For smaller voids, our Flash Patch product can make your life very easy. With a simple just-add-water mix design and the ability to have your patchwork fully set in as little as 45 minutes, there really isn’t a better product on the market to deal with your concrete patching issues.
What causes spalling to occur in concrete slabs and walkways?
Whether it was the slump of the concrete, a bad mix, improper screening / floating, age, or a direct cause of de-icing agents penetrating the concrete surface, spalling concrete is an eyesore and an issue that needs attention. When you factor in labor, time and material costs, the question becomes: can you create an affordable realistic solution for the conditions that originally caused the concrete to spall? Can the concrete restoration system also be environmentally friendly? Surecrete’s concrete restoration system provides solutions to both questions. Let’s look at what products are involved and why they are recommended.
How to Restore Concrete
Step 1 – Removing the spalled or damaged concrete surface and cleaning
Most contractors will begin with an aggressive pressure washing or scarifying of the concrete surface. The goal of this process is to remove all loose concrete and create a sound surface. An oscillating turbo tip and a pressure washer of 3,500 psi or greater will generally be sufficient. Using SureCrete’s SCR will clean, mildly de-grease, etch and profile the surface preparing it for your slip resistant thin concrete overlay. This product is environmentally friendly and will not harm plant life when rinsing the product off. Typical application is a 2-1 ratio of water to SCR.
Step 2 – How to hibernate unseen or future spalling and provide strength to damaged concrete
Prevention of further damage to the spalling concrete is not an exact science. A sound option for prevention is the use of a Lithium densifier. Why use Lithium Densifier? Use of Surecrete’s LD 1800 (lithium densifier) will harden and increase the surface PSI , slow moisture migration both south and north, and slow and in most cases stop efflorescence. Use of conventional sodium or potassium sodium hardeners is not recommended as they may leave a high concentration of salts deposited on the surface of the concrete and may add to additional surface cracking or scaling.
Step 3 – Address any pitting, spalling or patch deeper than 1/8th inch and repair the concrete slab
There are many quick patch concrete bag mixes, each varying in price. SureCrete’s Flash Patch is an ideal material choice for patching concrete or filling in damaged spalled areas. The reason for this is the fact that in many areas freeze-thaw can cause delamination of certain concrete patch material. Flash Patch gives you the strength and speed of hydraulic cement, the work time of 15-20 minutes and a premixed bonding agent to overcome freeze-thaw bonding. Couple that with a compressive strength of 6,200 PSI, Zero VOC, and single component, there is not another bag mix that compares in quality, strength or consistency.
In addition to those attributes this material allows you to patch all areas of the spalled concrete surface. Once applied your wait time is a matter of 15-30 minutes, then you can begin applying slip resistant thin concrete overlay.
Step 4 – How to choose and apply a slip resistant thin concrete overlay
Are you looking for a fresh broomed concrete surface or would you like to upgrade your concrete look and go with a decorative concrete pattern or texture? If you chose a fresh broom finish, SureBroom is the smart choice. SureBroom is a single component (just add water) mix, Zero VOC thin concrete overlay that delivers a fast cure time and a compressive strength of 6100 PSI. SureCrete suggests a two coat process as each coat is about 1/16th of an inch and will not completely cover over minor spalled damage. The second coat will bring the damaged spalled concrete surface back to smooth. The tools you need to apply SureBroom are metal squeegee, horsehair or nylon horsehair concrete broom, mixing paddle on drill and a 5-gallon empty pail to mix in. This system delivers simplicity of technique and a low material cost without compromising strength, quality or longevity to your new slip resistant thin concrete overlay coating.
Step 5 – Choosing a quality concrete sealer to protect against damage & weather
Most contractors prefer the use of a solvent acrylic sealer. The reason for this choice is that a quality solvent acrylic sealer will provide deep penetration into the concrete and increase adhesion. If applied to the correct thickness, it will minimize the slicking off of the slip resistant thin concrete overlay that was applied to the spalled concrete surface. Which concrete sealer do you choose? We suggest a solvent acrylic sealer with 20% solids. SureSeal Pigmented or HS 260 will deliver the needed attributes and aid in repelling deicing agents and preserving the slip resistant thin concrete overlay from spalling and other causes which deteriorate the surface.
A common question after the application is how often should we reapply sealer? We would love to give a solid timetable like 2-5 years but the simple fact is many factors come into play that de-grease the life span of a sealer. How can you tell if your sealant is weakening? Try a water test. When water is applied to the surface it should bead up as water would on a waxed surface. If the water beads your protection is still sound. If you desire to keep the clean shiny look of your surface reapply a single coat of a quality 20% solid solvent acrylic sealer like Surecrete’s HS 260.
