How LastiSeal® Concrete Stain & Sealer Works

concrete stain galleryConcrete 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.

LastiSeal Concrete Stain and Sealer on PinterestWATERPROOFS 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. 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 fumes or strong odors.

Resulting color will vary widely depending on the porosity of the substrate, application method, and color of the surface (more porous areas will result in a darker color). Rough surfaces like stucco will result in an uneven coloring. 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 sized bottle of LastiSeal Stain & Sealer to check the resulting color on your concrete and that the stain has properly penetrated into the surface.

Go Wild With Color!

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.

Infinite Color Effects Mix, match, and faux finish from 36 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.

Even when treated with the same LastiSeal® color, no two concrete floors or walls will look alike due to factors such as the porosity and color of the concrete, as well as the application and ambient conditions. No two floors will look alike!

GET FANCY - You can use a brush, sponge, rag, or similar faux-finishing techniques. Like decorative contractors, you can create sophisticated color patterns by use of stencils or masking areas with painter’s tape. 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 and Masonry Sealer. Or you can use it to seal the concrete without adding color.

Commercial and Residential Uses

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.

Common Commercial Uses Common Residential Uses
Foot-traffic areas (sidewalks, patios) Basement floors, walls
Hotel valet, Parking area Slab-on-grade homes
Retail flooring (breweries, restaurants, lobbies) Driveways, garage floors
Concrete curbing Patio, Walkways
Murals (highway art, building facades) Pool Deck
Statues, Signs, Monuments Outdoor decorative walls, retaining walls
Warehouse Floors Pavers

Limitations

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 the stain to percolate 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!

Concrete Preparation is Critical to Success

While the deep-penetrating LastiSeal® Concrete Sealer penetrates tighter concrete surfaces, stain pigment granules do not and will just dry out on the surface. If the surface is not properly prepared, you will likely end up with a concrete that is permanently waterproof but with a stain that will wash off.

Concrete prep is critical and the responsibility of the user. The concrete must be clean, thoroughly dry, and porous.

NEW CONCRETE – Allow it to cure for at least a month to fully develop capillaries (pores). New concrete is caustic (pH over 11) which can break down paints or stains. As it cures, its alkalinity gradually drops but it may take 1 or even 2 years indoors. High pH level can be lowered by acid washing the surface. Test with pH test strips widely available in stores and online. The required pH range is 9 to 6.

TIGHT SURFACES – Like all stains, LastiSeal Stain cannot permeate hard-troweled, burnished, or polished concrete surfaces common on slabs-on-grade floors in stores, restaurants, factories, warehouses, and some houses.

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.

OPENING TIGHT SURFACES –  Your options include acid etching, grinding, sanding, vacuum shot blasting, or light sandblasting. You can avoid hazardous acids by using our organic and environment-friendly PowerEtch Concrete Etcher & Cleaner.

Never assume your concrete surface is porous enough!

Most contractors take the safe approach and always, always acid etch or grind the concrete surface before staining, which we also strongly recommend. After acid-etching, you must neutralize the surface with a baking soda solution or when outdoors, ammonium solution.

Get a sample of LastiSeal® Concrete Stain and apply it to an inconspicuous test area to confirm that it penetrates and that you like the resulting color. Let it cure for at least three days and performs the "wet rag" test – try to rub the stain off with a wet rag and it should not come off.

APPLICATION - DO NOT OVER APPLY! One application in a thin glistening film is usually enough for poured concrete. A second application can be applied on more porous substrates to achieve a more intense color, particularly with lighter stains. Test the second application first on an inconspicuous spot first to make sure the stain is absorbing well enough.

IF THE STAIN DOES NOT PENETRATE, THE PROBLEM IS THE CONCRETE PREP OR THE APPLICATION BY THE USER.

Please take the time to read LastiSeal Stain Application and Tips to avoid potential pitfalls. It also describes the recommended "eyedropper test" of concrete porosity.

Penetration of the stain depends on concrete preparation and its application, which is the responsibility of the user. Please refer to our Application Instructions and Tips webpage. We strongly recommend you test the product first by purchasing a small 8-oz sized bottle. Due to the wide variety of colors and sizes, LastiSeal Concrete Stain & Sealer is not returnable (similarly to custom-tinted paints in stores). Please review our Commercial Terms.

Liven Up and Protect the Stain with a Clear Coating

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. concrete wet lookA 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 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 it well enough, a clear coating will help LOCK IN THE STAIN and protect it against washing or wearing away easily.

Concrete Dyes Fade

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

Acid Stains Turn Dull

Chemical acid stains have become very popular for coloring concrete floors. They are made up of inorganic metallic salts dissolved in an acid and water solution. They react chemically with alkalis in the concrete which stains the surface. Unlike paints, they create a decorative variegated or mottled look. But there is a limited choice of colors –  only about eight hues, mostly tans, browns, terra cottas, and blue-greens.

Acid stains contain corrosive components that can cause eye and skin irritation and produce strong odors. Acid staining is labor intensive – after a proper concrete prep, acid staining, neutralizing the acid residue, rinsing, and drying, the thin stained layer must be protected with a clear coating. The surface requires regular maintenance – waxing or re-sealing.

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. 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 stains color only a thin surface layer that gets easily scratched and is hard to repair.

Check out the comparison Acid Staining Concrete vs. LastiSeal® Stain.

The water-based LastiSeal® Concrete Stain & Sealer represents technological progress in the choice of colors, durability, and waterproofing of the concrete.

Why Concrete Paints Do Not Last

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 Waterproofs and Strengthens Concrete

LastiSeal penetrates deep into the concrete 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.

Coverage

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.

Save Money!

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:

  • 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. (Color gradually fades or deteriorates.)

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