Plexibond is Boysen’s cementitious waterproofing system. It’s applied in places that come in direct contact with water and moisture. This is called positive-side waterproofing. So, where would you need it? Per the Boysen technical service department, here are areas of the house where it’s highly recommended that you apply Plexibond for waterproofing.

Firewall

As part of fire preventive measures, many structures in the Philippines, including residential homes and commercial buildings, are required by law to have firewalls. Firewalls act as shields in the event a neighboring property catches fire.

To make them as fire-resistant as possible, firewalls are made of concrete and have no openings. And, so they don’t stand out so much, firewalls are typically incorporated into the design of a home and are also coated with paint.

Hopefully, your firewall never has to come in contact with fire. What’s for sure, however, is that it will come in contact with water, and a lot of it, when it rains. Hence, experts recommend waterproofing it. Find an instructional video on how to apply it on vertical concrete surfaces here: How to use: Boysen Plexibond.

Roof Deck

A lot of Pinoys in urban areas will have a Roof Deck as part of the structure of their home. As we typically don’t have front or back yards, a roof deck provides the additional space for practical use such as for hanging laundry, hosting family gatherings, or simply lounging out and enjoying a bit of air.

Having said this, a roof deck is one part of the home that benefits the most from waterproofing, considering that the Philippines isa typhoon-prone tropical country. A roof deck that has undergone waterproofing using Boysen Plexibond should be able to withstand heavy downpours and storms.

Waterproofing a roof deck using Plexibond requires a different process compared to waterproofing a vertical surface. Find a guide here: How-to Guide: Waterproofing Your Roof Deck with Boysen Plexibond.

Bathroom

Naturally, waterproofing is a concern in bathrooms. There will be areas that come in direct contact with water, like the floor of a shower area, that will benefit from an extra layer of protection. And yes, you can use Boysen Plexibond for it.

Remember, Boysen Plexibond is applied on bare concrete, so it must be applied before you install tiles. It’s mixed with 6.5 to 7.5 kgs of cement to 4 liters of Plexibond. Do not use it as is or mix it with anything else other than cement. Tile grout, skimcoat, putty, or paint will not be a good match. Aim for a smooth finish so you have an even surface to work with when it’s time to place your tiles.

Concrete Canopy

Concrete canopies are another common feature of Filipino homes. You’ll typically find this over exterior doors and windows. Aside from serving decorative purposes, it also gives shade from the sun and additional protection when it rains. So, protect the canopy that protects you. Waterproof it too.

Keep in mind that for horizontal surfaces like canopies and roof decks, you will need to apply 3 to 5 coats of the Plexibond and cement mixture. That’s compared to the 2 to 3 coats when you apply it on vertical surfaces like firewalls.
