You are likely reading this article because you are interested in how best to prepare your concrete surface before applying LastiSeal® Concrete Stain & Sealer or RadonSeal® Deep-Penetrating Concrete Sealer. Maybe you have landed on this page curious to find a product that will take your concrete from looking drab to "fab"! Regardless of the intention, PowerEtch™ is the etching and cleaning solution that will properly clean, reduce pH, and prep your concrete floor.
When it comes to applying paints or surface sealers, coatings like epoxy or urethane, penetrating sealers, concrete stains, overlays or levelers, the key to success is the surface profile of your concrete. Penetrating sealers and stains need enlarges pores to absorb into and paints and coatings the "tooth" to hold onto. If proper surface conditions are not met than the fruits of your labor may fail over a short period of time, not to mention the money you’ve wasted on product!
POWERETCH™ ADVANTAGES = EFFECTIVE + NO NEUTRALIZATION + SAFER + QUICK APPLICATION
PowerEtch™ is specifically designed for cleaning and profiling smooth or power-troweled concrete floors, such as commercial or industrial flooring, garage slabs, slabs on grade, basement floors, and similar. PowerEtch is a commercial-grade waterborne etching solution that gives concrete and masonry the “tooth” or “roughness” it needs!
DID YOU KNOW? - Many acid etching products contain masking agents used to “mask” hazardous or pungent odors. PowerEtch has no added masking agents and features low odor with less fumes.
Shipping - PowerEtch™ is not sold in stores but is shipped directly from the factory to your door. Orders received by 2 pm ET (M–F) are normally shipped same day via UPS® Ground Delivery (ETA: 1-5 working days to lower 48 states). Expedited and International Shipping is not available for this product. Note that 5-gallon pails are only shipped by truck/freight delivery and the minimum shipping quantity is six pails of PowerEtch.
|PowerEtch™ Concrete Etcher & Cleaner|
PowerEtch is most commonly used for etching or cleaning concrete floors, garage floors, power, floated, or screed finished commercial floors, basement floors, slab-on-grade foundations, industrial floors, driveways, sidewalks, ramps, and masonry walls.
PowerEtch is not just for poured concrete. It can be safely used for cleaning stucco, brick, mortar, pavers, grout, concrete blocks, CMUs, and cinder blocks. Use PowerEtch for the purposes of:
ENLARGING THE PORES IN CONCRETE - Increase the porosity of concrete floors and outdoor slabs before applying LastiSeal® Concrete Stain & Sealer or other stains (stain pigments need to penetrate into the surface). Open up the pores in hard-troweled floors before applying RadonSeal® Deep-Penetrating Concrete Sealer or other penetrating concrete sealers.
PROFILING A CONCRETE OR MASONRY SURFACE - Use PowerEtch to give concrete the "tooth" or roughness required for paints and coatings, epoxies, urethanes, self-leveling compounds, and overlays. Often used on garage slabs, indoor concrete floors, commercial or warehouse floors. Surface preparation is considered the most important step of any resinous flooring application.
REDUCING THE ALKALINITY OF NEW CONCRETE - New concrete (less than 2 years old) is very caustic (pH over 11) and its pH must be reduced to below 9 or it will slowly "burn off" most stains, paints, and flooring adhesives. As concrete cures, its pH level gradually drops but it may take months for outdoor concrete or a year or more indoors.
CONCRETE CLEANER - Remove efflorescence and stains from indoor or outdoor concrete and make it look fresh and more uniform. Efflorescence is the whitish mineral leached out of the concrete by water. PowerEtch helps to remove stubborn stains like "shadows" after oil spills, tannin stains from leaves/nuts/acorns, rust stains, and red clay.
DID YOU KNOW? Acid etching does not remove concrete sealers, paints, or coatings. They must be removed mechanically (shot-blasting, sandblasting, or scarifying) or chemically (paint strippers).
As contractors and homeowners are moving towards safer cleaning alternatives (without surrendering effectiveness), PowerEtch™ sets the standard as an industrial-strength concrete cleaning and etching solution formulated to be safer for the users and even the concrete. It took years to develop the optimal balance between safety and effectiveness.
“I am interested in using your LastiSeal Concrete Stain & Sealer product on my garage floor but I am unsure as how to best prepare the surface. Should I use muriatic acid before applying your products?” - Josh M., OR
For the average DIY homeowner who is preparing a concrete floor before staining, sealing, or painting, store-bought muriatic acid is not a user-friendly option. It is highly toxic, corrosive to the skin, and has a pungent odor that makes using it less suitable especially for interior applications. And unless you know exactly how to balance its concentration (pH), you run the risk of having a solution that may be too weak (less etching ability) or too strong (“burning” the concrete paste).
Etching solutions range from strong to mild (muriatic to vinegar) and there are pro’s and con’s to each. Typical chemicals used for etching concrete (concentration greatly affects their performance and toxicity):
Coverage rate varies greatly depending on porosity (approximate):
OUTDOOR CONCRETE: approximately 200-250 sq. ft. per/gal.
INDOOR CONCRETE: approximately 250-300 sq. ft. per/gal.
Before using PowerEtch the surface of the substrate must be sufficiently clean. Remove ground-in dirt, oils, grease, dust, paints or sealers, mold and mildew,and algae growth. The cleaned surface should not "bead" water.
DID YOU KNOW? Most acids will not clean concrete contaminated with oils or grease. Commercial-grade degreasers like our deep-cleaning Novion® Universal Concrete Cleaner should be used first before applying PowerEtch.
For best etching results, apply PowerEtch™ Concrete Etcher in suitable weather conditions:
Mask aluminum, soft metals, and glass. Cover or saturate plants, bushes, and grass surrounding the area with water.
PowerEtch™ is a ready-to-use etcher that can be simply applied using a hand-pump “garden” sprayer. Alternatively, you can use a plastic watering can or for small confined areas use a 3/4” paint roller.
- Stiff bristle broom.
- Clean water.
- Empty bucket, mop, or wet shopvac (indoor applications)
Use sound common sense practices during application (see MSDS sheet for health and safety precautions). Before opening, read all warning labels and data sheets. USE ONLY AS DIRECTED! KEEP AWAY FROM CHILDREN & PETS. CONSULT MSDS for precautions.
When reducing the alkalinity of young concrete, you can check it with pH test strips or pH pencil. The ideal resulting reading would be 7 (neutral) but a range of 6-9 is acceptable for most stains, paints, and flooring adhesives. If pH is still above 9, repeat the etching process. If pH is below 6, rinse the surface again to remove acid residue.
STAINING, SEALING, COATING – Allow the surface to dry thoroughly (at least 3 days) prior to applying stains, paints, sealers, or coatings.
