Super Stucco Sealer Stops a 98 mph Wind Driven Rain on Stucco Walls

What is Super Stucco Sealer?

Super Stucco is a clear, penetrating silane siloxane water repellent sealer designed for stucco, EIFS, plaster, and other masonry surfaces. It protects against water intrusion while maintaining the natural look of the surface.

How does Super Stucco protect against water damage?

Super Stucco penetrates deep into porous surfaces and creates a hydrophobic barrier that blocks liquid water while still allowing vapor to escape. This helps prevent issues like cracking, mold, and deterioration caused by moisture.

Does Super Stucco stop wind-driven rain?

Yes. Super Stucco has been ASTM tested to resist up to 98 mph wind-driven rain, significantly reducing water penetration through walls.

Will this sealer change the appearance of stucco?

No. Super Stucco is completely clear and non-film forming, meaning it will not alter the color, sheen, or texture of the surface. It also won’t yellow over time.

Can Super Stucco be used as a primer before painting?

Yes. It can be used as a primer before applying paint or latex coatings, improving surface performance and moisture resistance.

Is Super Stucco breathable?

Absolutely. It is 100% vapor permeable, allowing trapped moisture to escape while preventing water from entering—critical for long-term stucco performance.

What surfaces can Super Stucco be applied to?

Super Stucco is ideal for:

• Stucco walls
• EIFS systems
• Cement plaster
• Concrete and masonry surfaces

Is Super Stucco environmentally friendly?

Yes. It is a water-based, low VOC, eco-friendly sealer that meets environmental standards and is safe for use in residential and commercial projects.

Does it help prevent mold and mildew?

Yes. Super Stucco includes mold and mildew resistance, helping keep surfaces cleaner and reducing maintenance needs over time.

How much coverage does Super Stucco provide?

Coverage depends on surface porosity, but typical rates are:

• Stucco: 150–200 sq ft per gallon
• EIFS: 75–100 sq ft per gallon
• Clay Tile, Cement Plaster & Clay Block: 100–150 sq ft per gallon
• Cast Concrete: 150-175 sq ft per gallon

Is Super Stucco easy to apply?

Yes. It can be applied using a:

• Low-pressure sprayer
• Airless sprayer
• Pump sprayer

It’s designed for easy application with fast recoat times (30–60 minutes).

How soon can it be applied to new stucco?

Super Stucco can be applied as soon as 48 hours after new stucco or concrete is installed, making it ideal for new construction and fast-track projects.

How is Super Stucco mixed?

It is a concentrate:

• Mix 1 part Super Stucco with 9 parts water
• 1 gallon makes 10 gallons of ready-to-use product

Can Super Stucco be used in cold temperatures?

Yes. It can be applied in temperatures as low as 35°F, making it suitable for a wide range of climates.

APPLICATION INSTRUCTIONS

WORKING WITH CONCENTRATES

FOLLOW THESE SIMPLE APPLICATION STEPS
1. SUPER STUCCO should be applied using low-pressure airless or hand pump spray equipment
2. Do not atomize material (don’t want product to spray as a mist) as it will negatively impact product performance. For power sprayers, use large tip size of at least .035 to .051. For hand pump sprayers, turn spray nozzle at end of the spray wand so product flows out more like a steady stream and keep pressure up to amke sre enough material is coming out. Spray head should be held 8 to 12 inches from the surface so material floods down the wall at least 6-12 inches below the point of application.  For quickest application rate and to ensure a completely saturated surface suggest on powered spray equipment, remove the spray tip and on hand pump sprayers, remove the wand/tip. Product will flow very quickly, in a steady stream and completely eliminate atomizing.
3. Avoid application in windy weather.
4. Trigger gun off at the end of each pass to avoid using excessive materials. Stop all applications only at corners, joints, seams, or edges.
5. Multiple coats may be applied, whiting or yellowing will not occur.  A second coat is best applied “wet on wet” which means apply when first coat is damp but not yet dry.  Use same flood coat procedure.

PRECAUTIONS & LIMITATIONS
1. All surfaces to be coated should be clean of any dirt and grime, efflorescence, lime run, form oils and release agents, grease, mud, excess mortar, and mold and mildew, etc.
2. All cracks should be pointed or caulked. All voids, bee holes, masonry surface defects and openings such as conduits, pipes, drains, door frames, vents, air conditioner openings, electrical openings, control joints, or any dissimilar materials should be repaired using urethane or other approved patching.

STORAGE
Store materials in a well-protected area between 45° and 90°F. Avoid freezing temperatures, direct sunlight, and moisture. Keep away from heat sources.
