KILZ Basement And Masonry Waterproofing Paint
This premium interior/exterior paint is formulated to waterproof and seal porous concrete and masonry surfaces both inside and outside your home. The formula leverages nanotechnology to form a barrier that helps stop water infiltration, while an alkali-resistant coating provides a long-lasting, durable finish with decorative appeal. It is designed for properly prepped above- and below-grade basement walls, masonry walls, retaining walls, cinder and concrete blocks, stucco, and brick.
Do not use on floors or on walls with active water leaks. For best results, apply using a high-quality 1/2″–3/4″ nap roller, a 4″ nylon/polyester brush, or an airless sprayer capable of delivering 2200–3200 PSI with a .023″–.025″ spray tip. This coating is suitable for projects requiring a moisture-resistant, protective finish without a separate primer step.
KILZ Self-Priming Masonry Paint
This high-quality acrylic latex water-based paint offers excellent hiding properties with strong adhesion and water repellency on textured interior and exterior surfaces. It is a self-priming coating for properly prepared smooth, rough, and textured masonry, drywall, stucco, and brick surfaces. The paint is alkali-resistant up to pH 12.0, easy to apply, and cleans up with soap and water. It can be rolled, brushed, or sprayed for versatile application across various masonry scenarios.
Designed as a practical all-in-one solution, this product simplifies exterior masonry projects by combining primer and finish in one coat. It performs well on a range of substrates, including concrete, brick, stucco, and cementitious surfaces, and remains durable under outdoor conditions. Ideal for homeowners seeking straightforward coverage with reliable concealment and moisture resistance.
Glidden Total Exterior Paint & Primer All-in-One
This extremely durable exterior coating is ideal for properly prepared exterior wood, brick, masonry, and concrete, including weathered aluminum and weathered vinyl siding* as well as primed metal substrates. The paint provides strong resistance to fading, cracking, and peeling, and combines paint and primer in one seamless formula for easier, faster coverage. The finish is flat, delivering a clean, uniform look on exterior surfaces while delivering solid hide and long-term protection against the elements.
Glidden’s all-in-one approach helps maintain color integrity in harsh climates and reduces the need for multiple products. Surface preparation remains critical: clean, dry, and sound substrate, followed by appropriate cleaning and priming where required. This coating is a practical choice for homeowners seeking durable exterior color with reliable protection against weathering.
Zinsser 3100 PERMA-WHITE Exterior Paint
PERMA-WHITE is designed for exterior walls and items such as siding, trim, doors, foundations, gutters and downspouts, trellises and fences. The low-odor formula resists dirt and moisture for long-lasting durability, making it suitable for busy outdoor areas. It dries to the touch in about 30 minutes and covers roughly 300–400 square feet per gallon, enabling faster projects with fewer coats in many climates.
Because it targets exterior surfaces with a mild odor and solid durability, this product is ideal for homeowners seeking a reliable, easy-to-apply finish for walls and associated exterior elements. Proper surface preparation and suitable primers (where needed) can optimize performance on challenging substrates like old brick, wood, or masonry.
Liquid Rubber Color Waterproof Sealant
This elastomeric roofing coating is a versatile waterproof sealant for flat or slope surfaces, including roofs, foundations, basements, metal and concrete. It creates a flexible, seamless waterproof membrane that stops leaks and water damage, offering a professional-grade alternative to traditional roofing tar or shingles. One 5-gallon pail covers approximately 150–250 square feet, depending on surface texture and porosity, and the coating remains highly flexible over time.
Application is straightforward: brush, roller, or spray onto clean, dry surfaces. For best results on vertical or slope surfaces, apply 2–3 heavy coats; for flat roofs, aim for 3–4 coats. Complete curing typically occurs within 48 hours under favorable conditions. Do not apply in wet conditions or when rain is forecast within 24 hours, and keep surface above 50°F (10°C) during application and curing.
Buying Guide
When selecting exterior foundation paint, consider surface type, climate, and the level of waterproofing you need. Below are key purchase considerations and practical comparisons to help balance protection, aesthetics, and long-term maintenance.
- Surface compatibility: Choose coatings formulated for concrete, masonry, brick, stucco, or mixed materials. Elastomeric sealants excel for foundation leaks and hairline cracks, while acrylic latex paints offer good adhesion on many masonry surfaces.
- Waterproofing vs. decorative coating: For foundations and basements, prioritize moisture resistance and impermeability. Some products are self-priming or combined with primer, while others emphasize barrier properties or sealant performance on porous substrates.
- Finish and appearance: Flat or satin finishes reduce glare and hide surface imperfections; glossier finishes provide easier cleaning but show flaws more readily. Select a finish based on traffic, sun exposure, and aesthetic goals.
- Durability and alkali resistance: Masonry surfaces are highly alkaline; choose paints with alkali resistance to prevent chalking and loss of adhesion. Durability improves with the correct prep and compatible primers.
- Application method and equipment: Some coatings are best rolled, others brushed, and some are spray-applied. Consider available tools, weather, and project size to minimize prep time and ensure even coverage.
- Drying time and recoat windows: Fast-drying formulas speed up projects, but ensure proper curing between coats. Weather windows and humidity affect cure time significantly.
- VOC levels and environmental impact: Low-VOC formulas reduce odor and air quality concerns, especially for occupied spaces or homes with sensitivities.
- Maintenance and longevity: Look for multi-year durability and resistance to fading, cracking, and moisture intrusion. Elastomeric coatings may require maintenance cycles on very porous surfaces.
- Preparation and priming needs: Proper cleaning, repairs, and moisture preconditioning improve adhesion and final appearance. Some products are self-priming, but surface-specific prep usually remains essential.
In practice, match the product to the job: use waterproofing-focused coatings for exposed foundations and basements, all-in-one exterior paints for speed and convenience on exterior walls, and elastomeric sealants for ongoing moisture control on problem areas. Proper substrate preparation and correct application techniques are as important as the product choice itself to achieve lasting performance on exterior foundation projects.
