Direct Colors Penetrating Concrete Sealer, Hardener & Densifier is a clear, odorless, VOC compliant, water-based, matte finish concrete sealer, salt protectant and dust proofer that hardens, seals and densifies concrete. This matte finish concrete sealer provides no surface gloss and must be scoured using a red and black scouring pad on a high speed buffer after indoor floor applications to bring up a light shine and remove any residue caused by over-application.
Penetrating Concrete Sealer Hardener will extend the life of any exterior concrete slab by reducing spalling and other problems caused by extreme weather conditions. If desired, penetrating sealer can also be used in conjunction with an acrylic for a gloss finish.
Our sealer provides all the protection of a high-end penetrating water repellant sealer and offers all the benefits of a surface hardener, sealer, and densifier. This product penetrates and seals by reacting chemically with the concrete surface forming a clear, dense and durable inorganic topical surface layer that is breathable, abrasion-resistant, and hydrophobic.

How To Apply Penetrating Concrete Sealer
• Apply the Penetrating Concrete Sealer, with a pump up sprayer. Spray enough to create/maintain a uniformly damp surface for 20 minutes. Apply more sealer only to areas that appear more dry or absorptive than others. No membrane should be forming on the surface.
• Squeegee away any excess sealer remaining on surface. Do not allow sealer to pool anywhere on the concrete.
• Allow to dry for 24 hours and begin polishing from 400-grit up to 3000-grit. consider repeating this step to be absolutely certain all concrete acid stain has been neutralized before cleaning.

How To Apply Pentrating Sealer on Concrete Floors
1. Apply the Penetrating Sealer with a pump-up fence sprayer. Spray enough sealer to create/maintain a uniformly damp surface for 20 minutes.
2. Apply more sealer only to areas that appear more dry or absorptive than others. No membrane should be forming on the surface.
3. Squeegee away any excess sealer remaining on surface. Do not allow sealer to pool anywhere on the concrete.
4. Allow the concrete to dry for 24 hours before scouring the floor with a black pad followed by a red pad on a high-speed commercial buffer. Scouring provides enhanced durability and brings up a light shine while removing excess sealer residue. This step should not be considered optional for interior floors. The concrete will continue to harden for seven days after application.
Over-applying sealer will cause a milky, dull looking film on the concrete surface that can only be removed by scouring or applying an acid such as vinegar.
On an acid-stained floor, the surface must be completely neutralized, and all residues thoroughly removed before sealing. If concrete has not been properly neutralized and cleaned, a temporary “white dusting reaction” can occur between the sealer and the acid stain residue; it will typically disappear within two weeks of application and will not harm the final finish.
How To Apply Penetrating Sealer on Polished Concrete Coutertops
1. Polish to 200-grit. Acid Stain if desired and clean before sealing.
2. Apply the Penetrating Lithium Sealer with a pump-up fence and deck sprayer. Spray enough to create/maintain a uniformly damp surface for 20 minutes. Apply more sealer only to areas that appear more dry or absorptive than others. No membrane should be forming on the surface.
3. Squeegee away any excess sealer remaining on surface. Do not allow sealer to pool anywhere on the concrete.
4. Allow to dry for 24 hours and begin polishing from 400-grit up to 3000-grit.
How To Apply Penetrating Sealer on Vertical Surfaces
1. Apply from the bottom up using a low pressure, 10-25 psi sprayer with a fan-type nozzle. Use a foam brush to catch drips and runs during application.
2. Spray enough to create/maintain a uniformly damp surface for 20 minutes.
3. Flood the surface until excess runs down 6” to 8” below spray pattern nozzle or sponge surfaces sufficiently to create a uniformly damp surface.
Clean Up
Use water and a light detergent to clean applicators. Penetrating Sealer treatments are environmentally friendly and require no special or hazardous disposal methods.
Maintenance
- Use cleansers with a neutral PH only for floor maintenance (no citrus-based cleansers).
- Penetrating Sealers are chemical resistant and help reduce staining; however, citrus-based cleaners can damage the finish leaving the concrete surface vulnerable to staining.
- Regular maintenance will improve surface shine and prolong the life of the floor.
- Wipe up any chemical spills as soon as possible.
