LastiSeal Brick & Concrete Sealer is a unique, state-of-the-art, penetrating waterproofing sealer for brick, mortar, concrete, grout, pavers, and porous building materials. Backed by an 15-Year Service Life Warranty this waterborne, polyester-polymer and polyurethane sealer penetrates up to 4" inside brick, mortar, grout, concrete and masonry. LastiSeal internally fills the pores, bonds the substrate, and cures rock hard making the seal practically permanent!

If dusting, flaking, or cracking are concerns LastiSeal will strengthen and harden the surface thus preserving the life of your masonry. Once the seal has cured the surface will become noticeably harder and will make hammering a nail much more difficult. LastiSeal will shed surface water and spills while still allowing the substrate to breathe.

ECO-Friendly – LastiSeal Brick & Concrete Sealer is a non-toxic, nonflammable, and non-hazardous. No odor. ULTRA-LOW VOCs. Earth-friendly. Not harmful to plants, grass, or aquatic life. Safe for use indoors and out.

Unlike paints or surface coatings, LastiSeal Brick & Concrete Sealer is vapor permeable and does not form a surface film (coating) but internally seals and waterproofs the substrate. Water-repellent sealers sold in stores offer attractive water repellency but most are impermeable and will trap moisture. Major hardware store "sealers" normally need to be reapplied every year and in the long run, will cost you much more than using LastiSeal.

UV Resistant – Paints, coatings, and surface sealants are susceptible to flaking, peeling, cracking, or simply wearing away due to UV-rays, water or vapor pressure, saponification (reaction with lime from the concrete), efflorescence, and traffic. Eventually, you will need to remove the old paint (or it will start peeling even faster) and repaint the surface. Because LastiSeal penetrates deep into your brick it is not affected by ultraviolet rays.

• Use LastiSeal Brick & Concrete Sealer for the protection against:
• WIND-DRIVEN RAIN – Waterproofs brick chimneys, walls, facades against rain and surface water.
• NEGATIVE SIDE WATER PRESSURE – Prevents the transmission of water seepage through masonry.
• FREEZE-THAW – Protects brick, concrete and masonry against freeze-thaw damage and road salts.
• SPALLING – Hardens concrete and brick protecting it from pitting, spalling, dusting and crumbling.
• SPILLS – Resists spills, motor oil, grease, and chemical spills.
• MOLD, ALGAE - Reduces the growth of mold, mildew and algae. Makes for easier cleaning.
• HUMIDITY – Reduces water vapor transmission and indoor humidity.
• EFFLORESCENCE – Reduces unsightly efflorescence.

COVERAGE (per gallon)
The amount of coverage depends greatly on the porosity and composition of the substrate. Older brick (like Chicago brick), concrete, and masonry (+20 years) will require 2 applications for a proper waterproofing seal. Additional applications can be made next day or later.

• BRICKS – 1 application will cover 150-225 sq. ft.
• INDOOR POURED CONCRETE – 1 application will cover 200-225 sq. ft.
• OUTDOOR POURED CONCRETE – 1 application will cover 150-200 sq. ft.
• CONCRETE BLOCKS & POROUS MASONRY – 1 application will cover 100-150 sq. ft.

APPLICATION
Apply LastiSeal using a paint roller or a hand-pump garden sprayer (below 30 psi) with a fan pattern nozzle. Spray on a continuous thick glistening film on the verge of puddling. Back-roll puddles or run-downs. If applying with a roller, maintain a wet edge.
