  • A common problem with brick, paver, and stone surfaces is the accumulation of efflorescence. Efflorescence is salt deposits left behind after it has rained, or the surface has gotten wet. The salts in the brick, paver, or stone migrates to the top of the surface, leaving a white chalky film. It is especially important to remove efflorescence before sealing any surface or it will get trapped underneath the sealer, becoming nearly impossible to remove. Here are 5 easy steps to removing efflorescence:

    What You’ll Need:

    • Rainguard® Cleaner/Prep (Cleans up to 200 sq.ft./gallon depending on surface grime)

    • 1 Gallon Bucket or 1 Gallon Hand Pump Garden Sprayer

    • Synthetic Bristled Brush or Synthetic Bristled Broom

    Step 1:

    Spray a section of your surface with Cleaner/Prep using a hand pump garden sprayer.

    Step 2:

    Scrub surface by scrubbing with a broom or handheld brush to remove grime.  Spray and scrub small sections at a time. If a stain is especially stubborn, let Cleaner/Prep sit for a few minutes before scrubbing at the stain.

    Step 3:

    Repeat Step 1 & 2 as needed

    Step 4: 

    Rinse surface with clean water, removing any suds from the surface

    Step 5: 

    Wait at least 3-4 hours for Cleaner/Prep to completely dry before sealing your surface. If it is an overcast or cool day, it is best to wait at least 24 hours for the surface to completely dry.
