Concrete restoration and repair products are widely available from many concrete manufacturers. Few manufacturers provide a system that includes ALL the products needed to perform the entire process through a single brand name. With consumers across the United States dealing with damaged concrete surfaces due to: constant weather changes, de-icing agents, chemicals, grease, oil and more, the ability to restore and repair the concrete surface is essential.
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 degrease, 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.
Stage 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 are 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.
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 matter of 15-30 minutes, then you can begin applying 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, horse hair or nylon horse hair 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 with our compromising strength, quality or longevity to your new slip resistant thin concrete overlay coating.
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 delivers 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 application is how often should we reapply sealer? We would love to give a solid time table like 2-5 years but the simple fact is many factors come into play that decrease 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 shinny look of your surface reapply a single coat of a quality 20% solid solvent acrylic sealer like SureCrete’s HS 260.
