What makes LastiSeal® unique?
"New Product Stains and Seals Concrete in One Step" – Product review by Concrete Network.
Concrete is 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 SEALER - The sealer in LastiSeal® (polyester-based) penetrates up to 4", hardens inside the pores, and acts as the bonding agent for the stain. Backed by a 15-Year Waterproofing Warranty, LastiSeal® will both strengthen and waterproof the substrate for years to come.
2. PIGMENTED, SEMI-TRANSLUCENT STAIN - The UV-resistant color pigments penetrate and stain just below the surface for a long-lasting color.
WATERPROOFS CONCRETE – Compared to acid staining or other stains, LastiSeal is much more durable because it also waterproofs the concrete. This protects both the stain and the concrete against water and efflorescence. It is an ideal sealer for staining and waterproofing outdoor concrete such as, driveways, patios, sidewalks, pavers, and pool decks because it is completely slip-resistant. LastiSeal® is also is used indoors as a concrete floor sealer for basements, slab-on-grade floors, shops, and restaurants.
UV-RESISTANT – For durability of the color, LastiSeal® Concrete Stain & Sealer resists UV rays, as proven on many projects in Southern California, Florida, and Hawaii. Check out "LastiSeal to the Rescue"
ENVIRONMENT-FRIENDLY – Waterborne, no solvents, ultra-low VOCs compliant with all codes (CA). LEED Certified. Non-toxic, nonflammable, and non-hazardous. No strong odors.

|LastiSeal® Concrete Stain & Sealer|
|Earth Color Palette||Tropical Color Palette|
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 your “inner decorator” to come out!
LastiSeal offers an unrivaled 36 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 will result in a darker color). Rough surfaces like stucco will result in an uneven coloring.
Unlimited Color Effects – Mix, match, and faux finish from 36 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 concrete, use titanium-based stains – dark gray, forest green, mocha cream, or beach sand.
Coverage rate varies greatly depending on porosity (approximate):
CONCRETE FLOORS/SLABS - 200–225 sq. ft./gallon or 1,000–1,150 sq. ft. per 5-gallons.
OUTDOOR CONCRETE/MASONRY -150–200 sq. ft./gallon or 750–1,000 sq. ft. per 5-gallons.
Never assume your concrete surface is porous enough.
While the sealer in LastiSeal® Concrete Stain & Sealer more reliabley penetrates up to 4" inside the concrete, stains do not. In order to withstand the weather, foot and vehicular traffic, the stain must fully absorb just below the surface of the concrete without leaving behind a film. Stain is not a paint and if cured on the surface, will easily wash or wear off.
The composition of concrete, its porosity and color can vary greatly and on certain surfaces the use of LastiSeal® or any concrete stain is not advised. A smooth finished surface (power-troweled, screed finished) will not readily accept stains which can cause them to cure on the surface (acting more like a paint than a stain).
PREP - The concrete must be clean and porous. Etching or grinding the concrete surface is recommended to ensure proper surface porosity and help lower pH in young concrete (less than 2 years). Concrete etching solutions are not created equal. We recommend the use of our PowerEtch – Concrete Etcher & Cleaner to create a proper surface profile before the use of LastiSeal® Concrete Stain & Sealer.
TOOLS - Apply using a hand-held lawn or bug sprayer with fan tip nozzle, brush, sponge, rag, or similar faux-finishing techniques. The use of paint rollers is not recommended due to the susceptibility of leaving roller marks behind.
APPLICATION(S) - DO NOT OVER APPLY! ONE APPLICATION IS RECOMMENDED and normally sufficient for poured concrete. A second application can be applied on more porous substrate to achieve a more intense color, particularly with lighter stains. Always test a second application on an inconspicuous spot to ensure the stain is absorbing well enough.
GET FANCY - Like decorative contractors, you can create sophisticated color patterns by use of stencils or masking areas with painter’s tape. Taped edges are not as sharp with stains so most concrete contractors prefer cutting grooves into the concrete to create a tile effect.
Depending on the type of surface it has been applied to, LastiSeal® Concrete Stain & Sealer leaves behind a matte finish (flat) or a low-gloss finish (satin) on smoother surfaces. A clear topcoat will not only liven up the color but also protect the stain against wear and scratches (common practice when applied commercial/indoor flooring).
If you prefer an attractive high-gloss finish, there are several options for adding a clear coating over the stained surface. The sealer in LastiSeal® is a great primer for both solvent and water-based paints and coatings like acrylics, urethanes, epoxies, waxes, and polyaspartics.
Preferably, use water-based coatings indoors instead of solvent-based to avoid noxious fumes and odors. However, solvent-based sealers usually create the deepest gloss. Anti-friction additives will prevent slippery surfaces when wet.
CLEAR ACRYLIC - 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.
CLEAR URETHANES or EPOXIES - 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.
WAX -Inexpensive and easy to apply. A sacrificial coating that needs regular re-application. Some professionals like the deep "wet look" of several layers of wax the best.
THAT "WET LOOK" - Concrete coatings and various hybrids are readily available in home improvement centers or paint stores.
Did You Know? - If by chance you have applied too much of the product or if the suface has not absorbed the stain well enough, a clear coating will help LOCK IN THE COLOR and protect it against washing or wearing away easily.

LastiSeal® Concrete Stain & Sealer seals, stains, and protects a wide range of porous building materials – new or old, indoors or outdoors:
You can also stain walls, which is impossible with 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 or to add gloss, cover the stained surface with a sacrificial layer of wax or a strong clear coating.
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
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:
The acids are not healthy to the applicator or the environment.
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.
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.
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:
