"New Product Stains and Seals Concrete in One Step" – Product review by Concrete Network.
Concrete is porous. Residential concrete typically contains 12 – 15 percent air, but the pores (capillaries) are invisible, much smaller than the diameter of a human hair. The pores let in water vapor and eventually, liquid water by wicking or under pressure. LastiSeal is unlike other concrete stains, it combines two main ingredients:
1. DEEP-PENETRATING SEALER - The polyester-based LastiSeal® sealer penetrates deep (up to 4"), hardens inside the pores, and acts as a bonding agent for the stain. LastiSeal® waterproofs, strengthens, and protects the concrete and the stain itself for years to come. Backed by a 15-Year Waterproofing Warranty.
2. MINERAL STAIN PIGMENTS - The finely ground, UV-resistant color pigments, permeate and stain the concrete below the surface providing 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, alkalis, and efflorescence.
UV-RESISTANT – For durability of the color, LastiSeal® Concrete Stain resists UV rays, as proven on many projects in Southern California, Florida, and Hawaii.
ENVIRONMENT-FRIENDLY – Waterborne, no solvents, ultra-low VOCs compliant with all codes (CA). LEED Certified. Non-toxic, nonflammable, and non-hazardous. No fumes or strong odors.

Acid stains are limited to only about eight hues – variations of brown, tan, terra cotta, and soft blue-green. LastiSeal® Concrete Stain & Sealer allows your inner "home decorator” to come out! Turn that dull concrete into your personal canvas and enhance the appearance and curb appeal of your home.
Resulting color will vary widely depending on the porosity of the substrate, application, and color of the surface. More porous areas will result in a darker color. Even when treated with the same LastiSeal® color, no two concrete floors or walls will look alike!
The resulting color may be quite different from the palette and cannot be guaranteed. We strongly recommend that you first test with a small 8-ounce bottle to check the resulting color on your concrete and that the stain has properly penetrated into the concrete.
INFINITE COLOR EFFECTS – Mix, match, and faux finish from 37 color choices. You can combine colors by mixing them together before the application or by applying a second light application on top of another hue. Create an infinite array of colors and effects using faux finishing techniques. Try for a distinctive "antiqued," "variegated," or "marbled" appearance. The concrete can be stained to mimic polished marble, natural stone, or even stained wood.
GET FANCY – You can brush, sponge, rag, or use similar faux-finishing techniques when staining concrete. Mimicking decorative contractors, you can create sophisticated color patterns by use of stencils or masking areas with painter’s tape. But taped edges are not sharp with stains – most concrete contractors prefer cutting grooves into the concrete to create a tile effect.
If you prefer a more opaque color (less translucent) to hide blemishes in the concrete, use the titanium-based stains – dark gray, forest green, mocha cream, or beach sand. If you prefer a less intense color, dilute the stain by mixing it with the clear LastiSeal Brick & Concrete Sealer. (Do not use water!) Or you can use it to seal without adding color.
""Everyone who has seen our floors, bar none, cannot believe that they are concrete! ... My wife used a sponge to texture the sealer and everyone thinks that the floors are natural stone." – Morgan P., IN
"...LastiSeal Color Stain to my 6-year old concrete driveway primarily to enhance its appearance. Used the Rustic Brown which closely matches the brick on my house and sidewalk. Can't begin to tell you what an incredibly positive change it has made in the driveway's look!..." –Lloyd H., KY
"... my covered patio for a cycle garage and it came out so well, I will be doing another section of the patio. Oil spills are just wiped up, and tire marks don't show at all..." – James C., AZ

Coverage depends on the porosity and composition of the substrate (approximate):
Proper penetration of the stain depends on concrete composition, preparation and application, which is the sole responsibility of the applicator. While the sealing chemicals in LastiSeal reliably penetrate concrete surfaces, the added pigment granules may not. If the surface is not properly prepared, you will likely end up with a concrete that is waterproof but the stain will quickly wash off or wear away from the surface. Concrete prep is critical for the longevity of the stain. It should be hard to remove the color stain with water. Sampling the product first is strongly recommended!
CLEANING – The substrate must be clean and bare, unpainted, and thoroughly dry prior to application of LastiSeal.
POROSITY – Never assume the concrete surface is porous enough! Licensed decorative concrete contractors take the safe approach and always acid etch or scarify the concrete surface before the use of water-based stains. Your options include acid etching, grinding, sanding, vacuum shot blasting, or light sandblasting. After acid etching, neutralize the surface with a solution of water and baking soda or ammonium solution. You can avoid hazardous acids by using our industrial-strength, non-corrosive PowerEtch Concrete Etcher & Cleaner. Flush the surface with plenty of clean water afterwards.
pH – The pH of of cement based masonry must measure between 6-8. New concrete (up to two years of age) is highly alkaline and can break down a stain or alter the appearance. New concrete requires pH adjustment. Review the detailed application instructions and "Hard to Stain Surfaces" below.
APPLICATOR – It is recommended that LastiSeal® Concrete Stain & Sealer be applied using an airless or low-pressure hand-pump "garden" sprayer. When spraying is not practical, a 3/4" nap paint roller or brush may be used.
APPLICATION – One application is recommended and normally sufficient. Adjust nozzle to flat-fan pattern and spray a glistening film onto the surface. Just on the verge of puddling. DO NOT OVER APPLY!
The penetration of water-based stains ranges from 1/32 to 1/16 of an inch. LastiSeal® Concrete Stain & Sealer leaves behind a matte finish (flat) or a low-gloss finish (satin) on smoother surfaces. A clear topical coating will not only make the hues more intense but will also protect the stain against wear and scratches. It's the common practice on both commercial and residential floors.
If you prefer an attractive high-gloss finish, there are several options for adding a clear coating over the stained surface. LastiSeal® Sealer is a great primer for both solvent- and water-based coatings like acrylics, urethanes, epoxies, polyaspartics, and hybrids. Or you can use floor wax on indoor surfaces.
Water-based coatings avoid noxious fumes and odors on indoor applications. Solvent-based sealers often create the deepest gloss but make sure to just spray them on instead of rolling or brushing, which would smudge the stain. They are also suitable for garage floors to protect against de-icing chemicals.
CLEAR ACRYLIC - Available in paint stores, softer than urethanes but almost half the cost. Ideal for outdoor applications because of resistance to UV-rays. Soft, susceptible to scratching, and "hot tire pickup." Need regular re-applications. Permeable to water vapor.
CLEAR URETHANES / EPOXIES - Available in paint stores but more expensive. Much tougher than acrylics and scratch-resistant but not for outdoor use because they tend to yellow due to UV-rays. Not "breathable" – they trap moisture.
FLOOR WAX - Inexpensive and easy to apply. A sacrificial coating that needs regular re-application. However, some professionals swear by the deep "wet look" of several layers of wax.
"WET LOOK" - Concrete coatings and various hybrids readily available in stores. They make the colors appear darker and more intense.

Did You Know? - If by chance, you have applied too much of LastiSeal Stain or if the surface has not absorbed the stain well enough, a clear coating will help "lock in the stain" and protect it against chemical spills, scratching, or wearing away easily.
NEW CONCRETE – New concrete is highly caustic (pH over 12) which can cause paints to bubble and stains to breakdown. As concrete cures the alkalinity will gradually drop, but it may take 1 – 2 years for that to happen. A high pH level can be lowered by acid washing the surface then tested with pH test strips afterwards (electrical pH meter testing is recommended). The required pH range is 9 to 6.
TIGHT SURFACES – Like all stains, LastiSeal Concrete Stain & Sealer cannot permeate hard-troweled, burnished, polished or overly smooth concrete surfaces. Common for slab-on-grade or monolithic slabs, garage floors, some "walk-out basement" floors, retail, warehouses, hotel lobbies, and showroom floors.
PREVIOUSLY PAINTED OR SEALED SURFACES – Thoroughly remove old paints or sealers. The problem is that the pores in the surface may be still filled and could block the stain from penetrating.
Stains cannot penetrate non-porous surfaces:
1. STAMPED CONCRETE – Even after removing the surface sealer, the packed hard surface and release agents used during stamping prevent the penetration of stains and sealers. However, there have been successes on old, well-weathered stamped concrete driveways.
2. SUBMERGED CONCRETE – The stain will not last in continuously submerged surfaces like in swimming pools, fish ponds, or showers.
3. PATCHING COMPOUNDS, SURFACE LEVELERS – Polymer-modified surface levelers are not porous.
4. PRECAST CONCRETE – Ultra tight surface of factory-made concrete panels.
5. FIBER-REINFORCED CONCRETE – Often contains additives that may prevent proper penetration of stains.
6. CALCIUM CHLORIDE – An additive still sometimes used in cold climates, although harmful to concrete. If not properly mixed, it leaves shiny "brownish" areas that will not allow stains to penetrate into the concrete.
There are materials that are almost impossible to waterproof because of large pore. Some lightweight CMUs, split face blocks, or old masonry already badly deteriorated by extensive water seepage. Even three applications of LastiSeal may not fully waterproof such materials!
We recommend purchasing a small 8-ounce test bottle of LastiSeal® Concrete Stain & Sealer to confirm that you like the color and most importantly, that the stain is properly penetrating the surface. Similar to paint, a small sample area may not be completely representative of a larger scale applicaiton.
Since LastiSeal® Concrete Stain waterproofs concrete and is slip-resistant, it is also ideal for outdoor concrete. Unlike acid stains, it can be also used on vertical surfaces.

Check out the comparison Acid Staining Concrete vs. LastiSeal Concrete Stain.
Freshly acid-stained concrete looks spectacular. Unfortunately, many homeowners are disappointed when the color turns dull or dark brown after several 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. It means grinding and re-staining again! Why concrete acid stains deteriorate:
Similarly to wood, you can color concrete with a dye. They color the surface uniformly. Paint stores also sell universal tints, which produce opaque colors.
But the problem is that they do not last. They are not UV-resistant and the color will fade in the sun. Rain will wash them off. Moisture coming up through the concrete carries efflorescence and alkalis, which will degrade the color. Although dyes do not trap water vapor like many paints, their color fades faster.
Concrete dyes and stains have become the latest trend in decorating concrete. Check Concrete Stains vs. Concrete Dyes
Floor paints will bubble, crack, or peel when exposed to migrating moisture from the concrete like in foundation slabs, basement floors, and garage floors. Capillary water wicking and water vapor pressure lift the paint film, as does efflorescence (mineral salts) brought to the surface by water.
The surface may be too smooth - modern paints require a certain minimal grit (100-120) for adhesion, which may require acid etching or grinding the surface. Direct sunlight (UV-rays) dulls and breaks down paints. New concrete is highly alkaline (caustic) and attacks paints by “saponification.” Moisture trapped underneath the paint film activates lime and alkalis in the concrete, which form efflorescence.
By re-painting over the old paint you will just trap more water vapor and speed up the peeling of both layers. On the other hand, repeatedly removing the old paint and re-painting is labor intensive and costly.
Epoxy paints are the most durable but expensive. They are nonporous and trap water vapor, which eventually makes them bubble and crack. That's why most flooring contractors guarantee epoxy coatings on slabs-on-grade for only 5 years. More on acrylic, epoxy, and urethane concrete paints.
A better solution would be coloring the concrete without leaving a surface film in order to avoid trapping moisture. We all know from experience with wood that stains last much longer than paints – stains cannot peel. LastiSeal® Concrete Stain & Sealer provides the ideal solution – it seals the substrate internally against migrating moisture and does not form a film on the surface.
However, if you have to paint the concrete, deep-seal it first with RadonSeal Penetrating Concrete Sealer to protect the paint and the concrete.
LastiSeal penetrates deep into the concrete (up to 4") and hardens as a plastic. It's similar to injecting epoxy into the pores! This permanently strengthens and waterproofs the concrete.
Very porous concretes may require two or even three applications for waterproofing but you must avoid creating a buildup of stain on the surface! LastiSeal® Concrete Stain & Sealer cannot waterproof materials with very large pores like some lightweight CMUs, old Chicago brick, split face blocks, or older masonry already badly deteriorated by extensive water seepage.
Waterproofs poured concrete, concrete blocks, pavers, and bricks. Smooth surfaces may bead water.
Protects the Surface: Keeps out contaminants, road salts carried by water, spills, and chemicals. Protects outdoor concrete against freeze-thaw damage. 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 that gradually leaches out and degrades concrete.
Reduces Vapor Transmission: It will make your basement feel less humid.
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!
Reduces Molds and Mildew: Keeps out moisture and prevents molds from growing deep inside the pores in concrete.
LastiSeal Stain will save you money because it combines two products into one – waterproofing and staining, and because it lasts and lasts! Putting aside the waterproofing benefits, a quick comparison with other concrete coloring options:
