Penetrating concrete sealers | Do-it-yourself basement waterproofing | Basement and concrete repairs
LastiSeal™ Concrete Stain & Sealer is a technological breakthrough – it waterproofs and beautifies concrete in one step. Add some color and excitement to your dull concrete! LastiSeal Stain is suitable for the most demanding contractors and building owners, creative artists, as well as homeowners.
Unlimited Color Effects! Mix, match, and faux finsih from 36 colors choices before or after application. for other color variations (see color palettes below.)
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.
LastiSeal Concrete Stain & Sealer does not leave a film on the surface. The penetrating waterproofing seal is permanent. There are no harmful acids. Check out the comparison Acid Staining vs. LastiSeal Stain & Sealer
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 SEALER - Penetrating sealer that absorbs deep (2–4") and hardens inside concrete and masonry. It is like filling the pores with a hard epoxy! It will permanently strengthen and waterproof the substrate. Backed up by a limited 10-year Waterproofing Warranty.
2. PIGMENTED STAIN - which colors inside and beneath the surface. UV-resistant for durability outdoors.
LastiSeal Concrete Stain & Sealer gives concrete an attractive semi-translucent mottled look unlike the uniform color of concrete paints or stains. It showcases the interesting natural texture of concrete. More porous areas absorb more stain and look darker. Similar to acid staining but without the acids and with many more color options.
Compared to painting and acid staining, LastiSeal Color Stain is much more durable because it waterproofs the concrete against moisture from the ground and it resists because it colors deeper. It makes a great outdoor concrete stain and waterproofing sealer for driveways, patios, and pool decks. It also is an ideal concrete floor sealer for basements, slab-on-grade floors, and restaurants.
Environment-Friendly! Water-based, no hydrocarbon solvents, ultra-low VOCs compliant with all codes. Non-toxic, nonflammable, and non-hazardous. No strong odors.
Our Diverse Product Line Of Concrete, Brick & Masonry Sealers
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 Color Stain lets your “inner decorator” out! It offers unrivaled 36 earth tones and tropical colors (plus a whitewash color). Check the color palettes:
Endless variety of colors and shades. You can combine colors by mixing together two colors before application or by applying a second application of another color. If you prefer a less intense color, dilute the Color Stain by mixing it with the plain LastiSeal Brick and Masonry Sealer. Faux finishing techniques can be used as well.

The resulting color varies widely, depending on the application method, porosity and color of the surface. Porous surface will have a darker color. Rough surfaces like stucco will result in very uneven coloring. We strongly recommend that you first use test samples to confirm the color and that the stain is absorbing well. (Note that LastiSeal sealer is not returnable.)
If you prefer a more uniform, less translucent finish to hide blemishes in the concrete, use titanium-based colors – dark gray, forest green, mocha cream, or beach sand.

LastiSeal Stain is best applied with a hand-pump "garden" sprayer or alternatively, when indoors, with a brush, sponge, rag, or paint roller (3/4" nap).
NUMBER OF APPLICATIONS: 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.
COVERAGE: (varies widely depending on porosity)
DO NOT OVER APPLY! The stain must be able to absorb into the surface instead of leaving a surface film (like paint).

LastiSeal Concrete Stain & Sealer seals, dyes, and protects a wide range of porous building materials – new or old, indoors or outdoors:
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.
LastiSeal Stain & Sealer has a matte finish (flat), or a low-gloss sheen on smooth concrete. If you prefer a glossy finish, there are several options for adding a clear coating over the stained surface:
The 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.
Before waxing or coating, let the LastiSeal Stain thoroughly dry out for 4 or 5 days.
LastiSeal is a great paint primer, except for latex or silicone. Acrylic, urethane, and epoxy coatings bond chemically to LastiSeal and adhere much better than to bare concrete. They also form a thicker and stronger layer because the already sealed concrete is less absorbent. But more importantly, the deep-penetrating LastiSeal sealer will protect the coating against moisture coming up from the soil.
The colorless "plain" sealer is LastiSeal Brick & Masonry Sealer, which uses the same deep-penetrating sealer to waterproof concrete. It leaves no color or film on the surface and has a matte (flat) finish. Or, if you would like some sheen, you can order LastiSeal Concrete & Brick Sealer – Satin.
LastiSeal Stain and Sealer penetrates deep into concrete (2–4") and hardens – like filling the pores with epoxy! Its waterproofing qualities are practically permanent - 10-year Waterproofing Warranty.
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.
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.
Similarly to wood, you can color concrete with a pigmented stain or 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. Rain will wash them off. The color will fade in the sun. Moisture coming up through the concrete carries efflorescence and alkalis from the concrete, which will degrade the color stain. Although stains do not trap water vapor like paints, their color dulls even faster.
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.
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:
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.
