Prep and test

Start clean and dry. Which one is your floor?

Just stained?

  • Let the stain dry completely.
  • Used acid stain? Rinse until no residue is left.
  • Give it a light vacuum, careful not to scratch the stain.

Old concrete or pavers?

  • Clean with ProClean Degreaser™, then rinse until no residue is left.
  • Let it dry for at least 24 hours.
  • New concrete? Wait at least 28 days.

Then do the water test

Pour a little water on the floor. It must soak in within 3–5 minutes.

Soaks in

You’re ready to seal.

Beads up

There’s an old sealer. HydroCryl™ only goes over a water-based sealer, so strip any other kind first with Destiny™ Stripper.

Sits on top

Etch it with CitrusEtch™, then test again.

No tape on the surface: the adhesive keeps the sealer from bonding.

Seal when the surface is between 50 and 95°F.

Never let the jug freeze. A jug that has frozen is ruined. Contact us for a replacement.

Roll

A 3/8″ nap roller, a tray and an extension pole.

  1. Shake the jug and pour it into the tray.
  2. Load the roller, then roll off the extra on the tray’s ridged ramp.
  3. Work in small sections: roll a large W, then fill it in with even, overlapping strokes without lifting the roller.
  4. Go slowly, or you’ll get tiny bubbles.

Dry and recoat

Wait 1 to 2 hours, until your thumb doesn’t leave a fingerprint.

Then roll on a second thin coat the same way. Two thin coats. Add a third thin coat only if water doesn’t bead after two, or the finish looks uneven. Thick coats stay soft and can turn milky.

Want more grip?Mix OxiGrip™ Anti-Slip into the second coat, or broadcast it onto the wet second coat with a spreader. Don’t back-roll it.
Clean your tools while they’re wetUse ProClean Degreaser™ and water.

Indoors? Finish with ProWax Polish™Two to three thin coats, 24 hours after sealing. It takes the daily wear, so your sealer doesn’t have to.
UpkeepNo fixed schedule: inspect, and reapply where it looks thin or worn. Indoors, ProWax Polish™ applied regularly keeps the sealer going for many years.

Before You Checkout

AcquaTint™ and OxiGrip™ are not compatible when used together directly. If you need added slip resistance, apply AcquaTint™ as your color layer first, then use OxiGrip™ in a clear topcoat with AcquaSeal™ or HydroCryl™.
