How-To Guide

Printable Penetrating Sealer How-To Guide

Step 1: Preparation

  • Cover areas at risk of over-spray with plastic drop cloth.
  • Newly poured concrete must cure for 30 days before application.
  • For existing concrete:
    • Remove paint or previously applied sealer using Soy Gel Stripper.
    • Remove carpet glue or other adhesives using Bean-E-Doo® Mastic Remover.
    • Remove any oils, dirt, debris, Soy Gel Stripper, or Bean-E-Doo® Mastic Remover using scrub brush and ProClean Degreaser™.
  • Verify absorption by pouring a cup of water in various areas. If not absorbed within five minutes, etch the surface with CitrusEtch™, then neutralize surface with ProClean Neutralizer™ and rinse thoroughly.
  • Allow the concrete to thoroughly dry before application.

Step 2: Application

Coverage rate is approximately 200 square feet per gallon. Coverage rates may vary based on concrete texture, surface porosity, and application method.

NOTE: Only apply Penetrating Sealer when surface temperature is between 40°F (4°C) and 95°F (35°C).

Caution: May be harmful if swallowed or ingested. Contact with skin can cause mild irritation. Avoid contact with eyes.


  • Remove all filters from pump-up sprayer.
  • Pour Penetrating Sealer into pump-up sprayer.
  • Spray a saturating coat of Penetrating Sealer on surface in slightly circular motions with irregular overlaps.
  • Keep surface wet with Penetrating Sealer for at least 20 minutes (spray more as needed).
    • As Penetrating Sealer cures, remove any excess on top of surface with a scrub brush or squeegee trowel.


  • 24 hours before foot traffic or placing heavy furniture
  • 48 hours before driving over surface or allowing parked vehicles

Pro Tips:

  • As Penetrating Sealer cures, a light lithium residue may form on the surface. This means excess Penetrating Sealer was not absorbed and should be removed with a stiff broom or swing buffer with a red or white pad.
  • Penetrating Sealer will not bridge or fill cracks and will not salvage honeycombed or structurally unsound surfaces.
  • To avoid droplets dripping onto surface: before releasing sprayer trigger, immediately place tip in a bucket


  • Clean tools and supplies with ProClean Degreaser™ and warm water

Tools & Supplies:

  • Pump-up sprayer
  • Plastic drop cloth
  • Scrub brush
  • Squeegee trowel
  • Spiked shoes (if using CitrusEtch™)

Disclaimer: Direct Colors does not warranty or guarantee results (outcomes). Concrete variations or improper application may cause unintended results. Test product on an inconspicuous or small area and allow to fully cure to ensure compatibility and desired result.
