We’ve written an article about Boysen Plexibond and how it turns your home waterproof, and we’re giving it another round in the spotlight. Since it’s been raining nonstop, we’ve been receiving inquiries about Boysen Plexibond on our Facebook page. We thought another article would help you understand more of what Plexibond is and what it isn’t.

In this article, we’ve round up some frequently asked questions about our featured Boysen product and made an infographic to answer each one.

Here are six important dos and don’ts when using Boysen Plexibond:

Boysen Plexibond DOs and DON'Ts

To recall our previous post, Boysen Plexibond is a specially formulated water-based acrylic polymer designed for mixing with Portland cement. We’ve had several inquiries about this and to give emphasis, note that you can’t use it on its own. A 4 Liter can must be mixed adequately with a 6.5 to 7.5 kg cement, this will serve as the solution to your water leakage problems. Use it on roof decks and firewalls provided that there is no existing paint or tiles.

Although the mixture works firmly on its own, we recommend you to apply your choice of topcoat for maximum durability and added protection. Choose from the wide-range of Boysen products to ensure quality and compatibility. Click here to find your paint. It is also advisable to use Boysen Plexibond on the positive-side of the wall or the side where the water pressure comes from.

DON’T apply Boysen Plexibond over a previously painted surface. Since it is a mixture of acrylic polymer and cement, it weighs heavier than a usual coating. To serve its purpose for a long time, it needs a bare and sturdy surface to adhere to. Scrape off the existing paint and prepare the surface properly before applying Plexibond to ensure a leak-proof paint job. Another popular question is whether or not you can use it on swimming pools – the answer is a BIG NO. Although it is a waterproofing system, you might want to reconsider using Plexibond on submerged areas such as pools and ponds due to the subjectivity of its use and exposure.
