Powdery, hair-like, growth on your bricks or blocks? Chalky mineral deposits on your concrete slab or foundation walls? If yes, you have efflorescence, and you are not alone.
The good news is that RadonSeal has changed the way contractors and homeowners deal with efflorescence. Say goodbye to harsh acids and dangerous chemical cleaners and say hello to a safer, more reliable, effective efflorescence cleaner.

|8-ounce – AVAILABLE SOON||$14||FREE|
Cleaning efflorescence used to require flushing concrete with muriatic, hydrochloric, or buffered phosphoric acids. These acids are extremely hazardous to your health and can damage surfaces. Breathing acid fumes will make you choke, and skin or eye contact can cause severe burns. Using these types of products outdoors is problem enough while working with them indoors is next to impossible.
RadonSeal Efflorescence Cleaner replaces the “old-school” acid cleaners. Put away your respirator and plastic suit. Choose the safer way to remove surface efflorescence, “sub-efflorescence” (efflorescence that exists below the surface of concrete), lime and mortar stains, as well as rust stains. Our efflorescence cleaner contains no phosphoric acid, muriatic or hydrochloric acid, bleach, abrasives, or petroleum distillates.
RadonSeal Efflorescence Cleaner uses an organic salt that acts like an acid, but is only considered a mild skin irritan and not corrosive. Suitable for industrial, commercial, and residential use. Use to remove deposits from basement floors, foundation walls, garage floors, retaining walls, brick, stucco, mortar joints, cinder blocks or any other surface that requires cleaning. RadonSeal Efflorescence Cleaner is the ONLY industrial- strength efflorescence cleaner made safe for use indoors and formulated STRONG to remove even the most stubborn of stains!
Efflorescence is a very common and frustrating problem. It appears when soluble alkali salts are carried to the surface of concrete and masonry by water. Once the water evaporates, the salts are left behind leaving a white’ish, mineral stain on the surface. Wire brush it off and more efflorescence eventually appears again. Try to cover it with paint and you will only discover the efflorescence building-up underneath, causing the paint to peel and lose its adhesion to the surface. Efflorescence is one of the main causes as to why paints fail!
Think applying a topical sealer will solve the problem? Think again! Clear membrane sealers will trap efflorescence, causing the appearance underneath to discolor. This is often described as blushing or hazing under non-breathable, clear epoxy, urethane, and acrylic sealers. In severe cases, efflorescence can cause sealer delamination. In fact, applying the “wrong type” of sealer may make your efflorescence problem worse!
Can efflorescence be stopped?
Removing existing efflorescence is the first step, but it is not the last. Water will continue to seep through the capillaries and evaporate, leaving behind fresh efflorescence. Do not paint or apply a topical sealant to the surface! That will trap water vapor and increase the moisture level inside the concrete. This will activate more efflorescence, which will start pushing off the paint or surface sealer.
Deep-Seal the Substrate – Waterproof the concrete or mortar deep inside to prevent water migration. How simple! No more efflorescence can be carried to the surface. Follow these simple steps:
STEP 1 – Remove the efflorescence with RadonSeal Efflorescence Cleaner.
STEP 2 – Deep-seal the concrete, concrete blocks, or cinder blocks with RadonSeal Penetrating Concrete Sealer. As RadonSeal reacts and expands, it will purge dirt and efflorescence from deep inside the pores to the surface for up to five days. It may look like a fine "whitish fuzz". Brush off loose efflorescence and clean the concrete again with the Efflorescence Cleaner. In case of brick walls, use LastiSeal Brick & Concrete Sealer. It will deep-seal the mortar against the movement of water (without purging the pores).
IMPORTANT – RadonSeal Efflorescence Cleaner is extremely effective for the removal of efflorescence, dissolved salts, lime, and alkalis. However, lime (calcium hydroxide) in the efflorescence gradually reacts with carbon dioxide in the air (carbonation), forming calcium carbonate (CaCO3). The carbonate is often difficult to remove and may require multiple applications of the Efflorescence Cleaner or mechanical abrasion.
COVERAGE – 200 sq. ft./gal (estimated)
SURFACE PREP– Remove paints, previous sealers, coatings, or adhesive. Remove paints easily with our Lightning Strip Paint Remover. Clean oil and ground in dirt. Oil deposits can be cleaned with a dish washing liquid (like Dawn) or commercial degreaser like our Novion Universal Concrete Cleaner.
RadonSeal Efflorescence Cleaner provides a user and environment-friendly way to clean concrete, bricks, and masonry. It works quickly, has no odor. Use outdoor or indoors.
STEP 1 – Apply liberally to affected areas using a sprayer, brush, or roller. Allow the cleaner to react and break down mineral deposits.
STEP 2 – While still wet, re-spray and scrub heavy deposits. Scrub with a wire brush.
STEP 3 – Rinse treated surfaces. Add water to treated surfaces to dilute and remove the cleaner.
RadonSeal Efflorescence Cleaner can be safely used on poured concrete, concrete blocks, bricks, stucco, pavers, and artificial stones. The cleaner chemically breaks down, and removes efflorescence, lime deposits, metal salt stains, and rust deposits. Typical concrete, brick, and masonry brick cleaning projects:
