Seal and stain concrete in one simple step

No Harmful Acids – LastiSeal® Concrete Stain & Sealer gives concrete an attractive, semi-translucent mottled look unlike the uniform color of concrete paints or stains. It will showcase the variegated natural texture of the concrete without leaving a film on the surface. LastiSeal® is water-based and contains no harmful acids making application easy and safe. Check out the comparison Acid Staining vs. LastiSeal® Stain & Sealer.

Go Wild with Color

Acid stains are limited to only a few variations of brown, black, and blue-green. Concrete paints also offer only a limited range of colors but LastiSeal® allows for your “inner decorator” to come out!

LastiSeal offers an unrivaled 37 earth tones and tropical colors (whitewash color not pictured). Resulting color can vary depending on the porosity of the substrate, application method, and color of the surface (more porous concrete swill result in darker finish). Rough surfaces like stucco will result in an uneven coloring.

Unlimited Color Effects Mix, match, and faux finish from 37 color choices. You can combine colors by mixing together the two before application or by applying a second application on top of another color. If you prefer a less intense color, dilute the stain by mixing it with the LastiSeal® Brick and Masonry Sealer.

If you prefer a more uniform color (less translucent finish) to hide blemishes in the concrete, use titanium-based colors – dark gray, forest green, mocha cream, or beach sand.

Application - Avoiding Potential Pitfalls

The composition of concrete and its porosity can vary greatly and on certain surfaces the use of LastiSeal and concrete stains is not advised. Please take the time to read Instruction, Application, Prep, & Tips to avoid potential pitfalls. See also our Sealing Guide.

LastiSeal® Concrete Stain & Sealer is best applied with a hand-pump "garden" sprayer or alternatively, when indoors, with a brush, sponge, or faux finishing techniques. You can create sophisticated color patterns by stenciling or masking areas with use of painter’s tape. Taped edges are not as sharp so most contractors - and experienced Do-It-Yourselfers - prefer cutting grooves into the concrete to create a tile effect

TESTING – We strongly recommend that you first purchase a test bottle (8-ounce) to confirm the stain and the sealer are properly absorbing into the substrate.

How LastiSeal Concrete Stain and Sealer Worksconcrete stain gallery

Concrete is very porous. Residential concrete typically contains 12 to 15 percent air but the pores (capillaries) are invisible, much smaller than the diameter of human hair. The pores let in water vapor and eventually, liquid water by wicking or under pressure. LastiSeal is not like other concrete stains. It combines two main ingredients:

1. DEEP-PENETRATING CONCRETE SEALER - The sealer in LastiSeal® (polyester-polyurethane) penetrates up to 4" and hardens inside concrete and masonry. It is like filling the pores with a hard plastic! It will both strengthen and waterproof the substrate for years to come. LastiSeal® is backed up by a 15-Year Waterproofing Warranty.

2. PIGMENTED STAIN - The color pigments penetrate and stain just below the surface making the color UV-resistant (sealer penetrates much deeper).

WATERPROOFS CONCRETE – Compared to acid staining or other stains, LastiSeal Color Stain is much more durable because it also waterproofs the concrete, which protects both the stain and the concrete. It is great for staining and waterproofing outdoor concrete like driveways, patios, and pool decks. It also is an ideal concrete floor sealer for basements, slab-on-grade floors, shops, and restaurants.

UV-RESISTANT – For durability of the color, LastiSeal Stain resists UV rays, as proven on many projects in Southern California, Florida, and Hawaii. Check out "LastiSeal to the Rescue"

ENVIRONMENT-FRIENDLY – Water-based, no hydrocarbon solvents, ultra-low VOCs compliant with all codes. Non-toxic, nonflammable, and non-hazardous. No strong odors.


One saturating application is usually sufficient for poured concrete, indoors or outdoors. A second application may be needed to waterproof very porous substrate or to achieve a more intense color, particularly with lighter stains.DO NOT OVER APPLY! The stain must be able to absorb into the surface instead of leaving a surface film.

CONCRETE SLABS/FLOORS – approximately 200–225 sq. ft./gallon or 1,000–1,150 sq. ft. per 5-gal. pail.

OUTDOOR CONCRETE AND POROUS MASONRY – approximately 150–200 sq. ft./gallon or 750–1,000 sq. ft. per 5-gal.

Coverage varies greatly depending on porosity.

Add a Clear Finish

concrete wet lookLastiSeal® Stain & Sealer has a matte finish (flat), or a low-gloss sheen on smooth concrete. If you prefer a high-gloss finish, there are several options for adding a clear coating over the stained surface:

  • WAX –  Inexpensive and easy to do. A sacrificial coating that needs regular re-application. Some pros like the deep "wet look" of several layers of wax the best.
  • URETHAANE SEALERS (clear) – Available in paint stores but a good-quality urethane for concrete is expensive. Much tougher than acrylics and scratch-resistant but not for outdoors because they yellow due to UV-rays. Not "breathable" – they trap moisture.
  • ACRYLIC SEALERS (clear) – Available in paint stores, softer than urethanes and almost half the cost. Ideal for outdoor applications because of resistance to UV-rays. Soft, susceptible to scratching and hot tire pickup. Permeable to water vapor.

THE "WET LOOK" – Concrete coatings and various hybrids are readily available in home improvement centers or paint stores. Preferably, use water-based coatings indoors instead of solvent-based to avoid noxious fumes and odors. However, solvent-based sealers create the deepest "wet look" finish. Anti-friction additives will prevent slippery surfaces when wet.

LastiSeal Concrete Stain & Sealer seals, dyes, and protects a wide range of porous building materials – new or old, indoors or outdoors:

  • Poured concrete, plain or integrally colored
  • Acid stained concrete (after removing the surface sealer)
  • Mortar, unpainted stucco, plaster
  • Bricks, pavers
  • Porous natural or man-made stones
  • Concrete blocks, cinder blocks, split face blocks
  • Concrete statues and memorials.

You can also stain walls, which is impossible for acid staining. LastiSeal Stain is great for concrete floors in restaurants, bars, and concrete countertops. The sealer is resistant to alcohol, wine, mustard, vinegar, and many kitchen products, provided they do not sit on the surface too long. To protect the surface against abuse or to add gloss, cover the stained surface it with a sacrificial layer of wax or clear coating.

Why Concrete Paints Do Not Last

Paint film will bubble, crack, peel, or wear off when the concrete is exposed to moisture like foundation slabs, basement floors, and garage floors. Capillary water seepage and water vapor pressure lift the concrete paint, as does efflorescence (mineral salts) brought to the surface by water.

Moisture trapped underneath the paint film activates lime and alkalis in the concrete, which attack the paint by “saponification.” New concrete is highly alkaline (caustic) and breaks down paints. The surface may be too smooth - modern paints require a certain minimal grit (100-120) for adhesion. Direct sunlight (UV-rays) dulls and breaks down paints.

Epoxy paints are the most durable but also expensive. They are nonporous and trap all water vapor, which eventually makes them bubble and crack. Most painting contractors guarantee epoxy coatings for only 5 years. More on acrylic, epoxy, and urethane concrete paints

Re-painting over the old paint would just trap more water vapor and speed up the peeling of both layers. However, repeatedly removing the old paint and re-painting is labor intensive and costly.

A better solution would be coloring the concrete without leaving a surface film, which avoids trapping moisture. We all know from experience with wood that stains last much longer than paints - stains cannot peel. LastiSeal Color Stain provides the ideal solution – it seals the substrate internally against moisture and does not form a film on the surface.

LastiSeal Waterproofs and Strengthens Concrete

The masonry must be sound and without excessively large pores. The sealer cannot waterproof materials with very large pores like some lightweight CMUs, old Chicago brick, split face blocks, cinder blocks, or older masonry already badly deteriorated by extensive water seepage. For more porous surfaces two - even three - applications would be required.

Waterproofs poured concrete, concrete blocks, pavers, and bricks. Smooth surfaces will bead.

Protects the Surface: Keeps out contaminants, road salts, spills and chemicals. Protects outdoor concrete against freeze-thaw damage and road salts. Reduces abrasion due to traffic.

Strengthens Concrete: Reduces crumbling, spalling, pitting, and cracking.

Reduces Efflorescence: The “white powder” is an evidence of capillary water seepage, which gradually leaches out and degrades concrete.

Reduces Vapor Transmission: Seal the substrate before installing flooring or covering the walls.

Reduces Concrete Dusting: Concrete dust contains very fine particles of silica – glass. When inhaled, they cut into the lung tissue. Seal the concrete before letting the children play in an unfinished basement!

Prevents Molds and Mildew: Keeps out moisture and prevents molds from growing inside pores.

Concrete Dyes Fade

Similarly to wood, you can color concrete with a dye. They color the surface uniformly and most are UV-resistant. Paint stores also sell universal tints, which produce opaque colors.

But the problem is that they do not last. They are not UV-resistant. Rain will wash them off. The color will fade in the sun. Moisture coming up through the concrete carries efflorescence and alkali from the concrete, which will degrade the color stain. Although stains do not trap water vapor like paints, their color dulls even faster. More on concrete stains vs. concrete dyes

Acid Stains Turn Dull

Concrete acid stains (chemical stains) have become very popular for coloring concrete floors. They use an acid to open up the surface and metallic salts, which react with alkalis in the concrete and create color. Unlike paints, they create a spectacular mottled look.

Acid staining is labor intensive and costly. After a thorough concrete prep, staining, neutralizing, and rinsing off acid residue, the stain has to be protected with a clear sealer. Contractors charge $2 to $4 per square foot and more. The stained surface requires regular maintenance – waxing or re-sealing to protect the thin colored layer.

There is a limited choice of colors but freshly acid-stained concrete looks really beautiful! Unfortunately, many homeowners are disappointed when the color turns dull or dark brown after a couple years. Acid stained concrete gradually changes color when exposed to moisture migrating from the ground. Blue-green color will slowly turn dull brown or even black. Why concrete acid stains deteriorate:

  • Migrating moisture re-activates the metallic salts in the surface, so they continue to react and darken the concrete.
  • Efflorescence, lime and alkalis from the concrete dull the color.
  • Acid staining colors only a thin surface layer that gets easily scratched.
  • The surface, which had been partially “eaten away” by acid, is brittle – it easily crumbles and wears off. 
  • Clear sealers, needed to protect the surface, may trap water vapor and activate efflorescence from the concrete.

The acids are not healthy to the applicator or the environment.

Cost Comparison

LastiSeal Stain will save you money because it combines two products into one – waterproofing and coloring. And it eliminates repeated paint removal and re-applications in the years to come. Other common options:

  • Heavy epoxy paint about $180/gallon. (Note that a paint may contain only 1 percent epoxy but can be sold as "epoxy paint.”)
  • Urethane paints about $90/gallon. (Resist abrasion but not UV-stable. Need an epoxy primer.)
  • Solid color acrylic concrete stain about $70/gallon. (Less expensive and UV-stable, but the softest surface.)
  • Acid stain plus coating about $60/gallon. (Very labor intensive, full cost $2–4 per sq. ft. Regular waxing required.)

LastiSeal Stain has made concrete painting and acid staining obsolete. It does much more, offers a much wider choice of colors, is permanent, and still costs much less.
