If you’re looking for a high-performance all-around polyurethane sealant that works on a wide variety of materials including masonry and concrete, it’s hard to go wrong with Masterseal Np1. This Masterseal sealant is a reliable mainstay of contractors and home DIYers alike, thanks to its versatility and affordability.
In this article, we’ll briefly cover the many highlights of Masterseal Np1 and why this particular Masterseal sealant is so widely used.
What Is Masterseal Np1?
Formerly known as Sonolastic Np1, this Masterseal sealant is a high-performance elastomeric gun-grade polyurethane sealant. It’s a one-component mixture, no mixing or priming is required. It’s ready to use straight out of the tube or sausage, reducing labor costs and usage time.
The overall joint flexibility rating is ±35%, which brings excellent flexibility without compromising its sealing ability. You can create clean, reliable joints quickly with Masterseal Np1.
In addition, it’s highly water-resistant and can even be immersed in water for short periods without losing its hold. This combined with its high resistance to hot and cold makes it an excellent all-weather sealant. Plus, it’s paintable, making it particularly attractive for use on residential buildings or storefronts.
How Can Masterseal Np1 Be Used?
This Masterseal sealant is rated for use on the following surfaces:
- Clay roof tiles
- Concrete roof tiles
- Any natural stonework
This makes Masterseal Np1 a superior choice in many different kinds of construction. It can be used in both interior and exterior applications, above or below grade. It’s perfect for use in joints where some level of expansion or flexibility is called for, such as window frames or panel walls. It could also be used along with vinyl siding or fascia.
Adding to its versatility in construction, it also comes in a wide variety of standard colors. These include:
- Redwood tan
- And many more!
The most important factor to remember when using Masterseal Np1 is that the substrate surfaces must be thoroughly cleaned before use, and then dried. If you’re applying it to surfaces that have been previously painted, be sure to remove all the old paint before using it.
This ease-of-use makes it perfect for so many applications!
