What is Sonolastic NP1 used for?
NP1 and NP1 are designed for sealing / caulking all types of active exterior construction joints. NP1 caulk sealant requires no mixing and bonds to most construction materials without a primer, including concrete, masonry, wood and most metals.
How long does NP1 caulk last?
Joint movement capability +/- 35%. 10.1 Oz tube. Shelf life: 12 months.
Is NP1 sealant waterproof?
NP1 isn’t merely water-tight, it can be fully submerged in water without losing its grip or seal. While not recommended for applications that will remain permanently submerged, it can resist even the most powerful sources of water.
What type of caulk is NP1?
elastomeric polyurethane sealant
Masterseal Np1 is a 1 component, high performance, non-priming, gun grade, elastomeric polyurethane sealant, it requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry.
What is Master Seal NP 1 used for?
Used as an acoustic sealant, MasterSeal NP 1 reduces sound transmission in partition systems to support high STC values by sealing spaces around cut-outs and at perimeters of partitions. Recommended uses: Interior and exterior. Above and below grade.
How long before NP1 gets wet?
temperature for at least 24 hours before using. subject to continuous water immersion, cure for 21 days at 70˚ F (23˚ c) and 50% relative humidity. allow longer cure times at lower temperatures and humidities. always use masterSeal P 173.
What is the longest lasting exterior caulk?
The longest-lasting sealants are silicones, urethanes and urethane hybrids, he says. Silicone and polyurethane sealants last the longest, Hess agrees, but are also the most expensive and difficult to work with. “They don’t tool very well, are hard to clean up and in the case of [traditional] silicone, not paintable.”
What does NP1 stand for?
NP1

What happens if it rains after caulking?
If caulk gets wet before it is allowed to completely cure, it’s formula won’t perform as intended. That could mean it’ll take longer than advertised to dry and cure or, worse, the tight seal you were hoping to create will be compromised. If the latter happens, you’ll have to remove the caulk and start the project over.
Can you caulk over old exterior caulk?
You can caulk over caulk. Just make sure that the old caulk is dry, clean, and oil and dust-free. Also, apply the new caulk to extend beyond the old, onto clean caulk-free surfaces to which it can adhere. However, for best results, you should remove the old caulk before applying a new caulk.
What is the best caulking for exterior wood?
Polyurethane is one of the best materials to use for sealing the exterior of a home. This exterior caulk is UV-resistant, so DIYers won’t have to look at ugly yellowing over time on what was once a clear bead of caulking.
How do you get NP1 caulk off your hands?
Next, apply baking soda to your hands and rub them together. The butter will lubricate and loosen the caulk while the baking soda will act as a gentle abrasive agent to scrub the caulk away. Use regular hand soap to wash off any oily residue left behind by the butter. Now you’ll have soft, clean hands.
Why is my clear caulk turning white?
Clear caulk that contains latex often appears white during initial caulking. This is due to the presence of water in the formula. As the caulk dries, the latex structure changes, causing the caulk to turn clear. Clear caulk that contains latex often goes on white and turns clear when dry.
Can you caulk over caulk?
Removing the old caulk and replacing it with a new bead of caulk instead usually creates a better seal. However, you can effectively caulk over caulk as long as the bottom layer of caulk isn’t damaged or moldy. The old caulk should also be clean, dry, and free of oil for the best adhesion.
Why is my new caulk cracking?
As the caulk dries, it shrinks and causes the paint film to stretch and crack. Applying caulk when the air, surface, or caulk temperature is below 40 degrees F, and the caulk is not designed for these conditions.
How long should Exterior caulking last?
You can expect exterior caulk to last 7 to 10 years, based on using acrylic latex or latex/silicone caulk with a coat of paint over it. This is also the average life of exterior paint, so an important part of repainting a home is redoing the caulk at the same time.
What kind of caulk is completely waterproof?
silicone sealant
Latex caulk and silicone sealant typically dry to the touch within 30-minutes, but they can take up to 24-hours to completely cure and be fully waterproof. Fast-drying formulas can cure in under 24-hours, depending on the temperature and humidity.
What is difference between sealant and caulk?
The key distinction between a caulk and sealant? Elasticity. Caulk is typically made from a mixture of latex and acrylic materials, which make it more rigid and prone to shrinking when cured. A sealant offers superior elasticity and water resistance because it primarily contains silicone.
Can you paint over NP1 caulk?
Yes, if your MasterSeal NP1 Sealant is completely cured and clean, it can be painted with elastomeric paint. Keep in mind not to use any oil-based caulking, sealants, or other products with asphalt, tar, or oil when using NP1 – this is very important.
Should I use white or clear caulk?
Clear caulk is good for sealing fixtures on tile or stone (such as in showers or around a kitchen sink). Use clear caulk where you do not plan to paint over caulk. White caulk is best used for sealing baseboards, trim, and siding. Use white caulk where you will be painting over the caulk.
