Sample Size Penetrating Lithium Based Sealer Hardener is a water based, matte finish concrete sealer for indoor/outdoor concrete and countertops. Sample sizes are perfect for smaller countertops, concrete decor projects or product testing. This sealer provides no surface gloss unless buffed with a high speed buffer. Use red and black scouring pads to remove any residue caused by over-application of the matte finish concrete sealer, and to bring a light shine to the surface. Perfect for polished countertops and integrally-colored floors. DCI Penetrating Lithium Based Sealer Hardener is not recommended for stamped, textured or broomed concrete.
Application: Apply pump-up fence and deck sprayer. Spray enough sealer to create a uniformly damp surface. Do not over apply. This sealer does not form a surface membrane and should not be applied in “coats.” Use a squeegee to prevent pooling and insure the sealer has been absorbed into the concrete. Use a squeegee to prevent pooling and insure a uniform sealer coat. Apply more sealer only to areas that appear more absorptive than others. Sealer should remain uniformly damp for 20 minutes. Allow concrete to dry for 24 hours before buffing the floor with a high-speed commercial buffer for enhanced durability, light shine and remove excess sealer residue. The concrete will continue to harden over 7 days. On acid-stained floors, the surface must be fully neutralized and all remaining debris or excess color removed before sealing. If concrete has not been properly neutralized and cleaned, a temporary “white dusting reaction” can occur; it will typically disappear within two weeks of application. For vertical applications, apply from the bottom up using a low pressure, 10-25 psi sprayer with a fan-type nozzle. Flood surface until excess runs down 6” to 8” below spray pattern nozzle or sponge surfaces sufficiently to create a uniform dampness. When a brush or roller is used, repeated applications should be made until the surface remains moist for a minute or so before solution disappears. Use cleansers with a neutral ph only for floor maintenance. See application instructions for complete details.
For countertop application, spray on the surface and carefully squeegee off any excess sealer. Once the surface has remained uniformly damp for 20 minutes, leave to dry and polish after 24 hours dwell time.
