Stucco Sealer Penetrating Water Repellent Protection For Stucco

The best stucco sealer for vertical stucco surfaces.

Protect, restore, and extend the life of your home with Rainguard Water Sealers Premium Stucco Sealer. This sealer is formulated with a water-based silane and siloxane blend to provide superior protection against wind-driven rain, mold, mildew, and other moisture damage. The penetrating formula means no film is created and the surface will not change in texture or appearance.

• Penetrating formula dries invisible
• Prevents growth of mold and mildew
• Stain resistant to oil, gas, and anti-freeze
• Will not yellow, crack, or peel – even in direct sunlight
• Great winterizing agent – Protects stucco from freeze / thaw damage
• Protects stucco from salt infiltration from salts in the air (i.e. from the ocean)*

*Looking for superior salt protection? Try Salt Guard.

What makes Stucco Sealer different? A proprietary ingredient called Micro-Lok™. This additive ensures the absorption of the sealer into the surface and creates a long-lasting hydrophobic barrier that is not affected by weathering, salt, dirt, freezing temperatures, UV light, and wind-driven rain, among many other damaging elements.

FAQ

>> Can I use this on painted stucco?

No. You will want to use Paint Sealer on your painted stucco.

>> Can I use this on color integrated stucco?

Yes. You can use this on color integrated stucco.

>> Can I paint over Stucco Sealer at a later time?

Yes. You can paint over Stucco Sealer but keep in mind it will not protect the paint from moisture damage. You may want to use Paint Sealer after the surface is painted and fully dry to protect the paint from moisture damage.

>> What is freeze / thaw damage?

You can read about freeze / thaw damage on our blog here.

>> What is the mix ratio for the concentrates?

For the quart concentrate that makes TWO gallons – Dilute 1 part concentrate to 7 parts clean water. Store any remainder in a temperature-controlled environment (meaning do not let freeze or overheat).

For the quart concentrate that makes FIVE gallons – Dilute 1 part concentrate to 19 parts clean water. Store any remainder in a temperature-controlled environment (meaning do not let freeze or overheat).

Additional information

Weather Conditions:

Apply during moderate temperatures when humidity and dew point levels are low. If it is expected to rain within 24 hours of application, postpone your project until weather conditions improve. If you need to store the product until a later date do not store in direct sunlight/high temperatures or allow the product to freeze. For more specific details please contact us by phone or email listed below.

Clean and Prep:

Gently brush out any stains with a soft bristle brush or rag using Rainguard Cleaner/Prep. If you plan on pressure washing, make sure to remove stains with Cleaner/Prep first. Once the surface is clean, make sure to let it dry until it is “bone dry”. This will allow the sealer to absorb deep into the surface for maximum protection. Think of your surface as a sponge. A wet sponge will not be able to absorb as much as a dry sponge.

Protect anything you don’t want sealed by moving it out of the way or covering it with a tarp or drop cloth (including your and/or the neighbors car). All Rainguard Premium Project Sealers are eco-friendly and safe for people, pets, and plants. A small amount of overspray on your plants or grass will not effect them. However, sometimes large leaf plants will show droplets from overspray, so you may want to move or cover them up before application.

Mixing:

READY TO USE products (white bottle) can be shaken lightly before use to disperse any settled material.

CONCENTRATES (black bottle) are the best value and mixing is simple. 1. For Eco-Pods or concentrates that make 1 gallon, empty the contents directly into a 1 gallon hand pump garden sprayer and fill with clean water. Mix lightly to disperse material. 2. For the quart concentrate that “makes 2 gallons”, empty the contents of the quart into an empty 5 gallon pail then add clean water to the 2 gallon mark. Mix lightly. Note: If there is no 2 gallon mark visible, first add 2 gallons of water into the empty 5 gallon pail and mark the water level with a sharpie marker. 3. For the quart that “makes 5 gallons”, empty the contents of the quart into an empty 5 gallon pail then fill with clean water. Mix lightly.

Application:

Always apply at least 2 (two) heavy coats of sealer to your surface. Older surfaces may require more than two coats, depending on surface porosity. Once the first coat is dry to the touch apply the second saturation coat. When the second coat is completely dry you can now put any decor, furniture etc. back on the treated surface.

Vertical Surfaces:

Spray starting at the top of the surface allowing the product to saturate and drip heavily before moving onto the next spot. Slowly spray in a horizontal cross hatch motion, maintaining at least a 6-inch drip or run down.

Horizontal Surfaces:

Spray the product until it starts to pool up slightly. You will know enough is applied in any given spot when the product starts to pool (puddle) up with a milky-white color. Although the puddling will dissipate slowly into the pores, you may wish to back roll or brush out puddles for a faster dry time.

For small areas such as bannisters: USING A BRUSH IS NOT RECOMMENDED. You may use a 1/4” nap roller, making sure roller is soaking wet and apply 3 coats per one spray coat (meaning a total of 6 coats rolled to equal two coats sprayed).

IMPORTANT: Avoid letting any water to come in contact with your newly sealed surface for 24 hours. After full cure time is achieved (approximately 4-7 days at 75° F) you can expect the full beading effect. Wait to test water repellency after the full chemical cure period. To conduct a test, simply drip some water in a few places where you have sealed the surface. If the drips make the surface darken, this is an indication that it is still absorbing, meaning you need to apply another coat. (This issue is most common with older surfaces).

Clean-Up:

Rainguard Water Sealers uses a water based formula. Simply rinse out equipment with clean water until it runs clear. Any undesired over-spray on windows or glass can be immediately wiped off with a clean cloth. If the product has already dried it can be washed off quickly with a clean cloth, warm water, and a mild soap.
