Homes in certain areas, such as those situated in places with high humidity, require a little more attention to prevent paint problems. The key is to apply and use the right methods and products from the beginning to avoid possible frustrations down the line. To help you out, we have come up with a waterproofing and painting guide as advised by experts at Boysen.

For places like Baguio and Tagaytay, one of the main problems homes experience is water seepage—a particular headache caused by the high humidity (aka lots of moisture in the air). Without proper waterproofing measures, homes in these areas are also more likely to see blistering and peeling paint, both of which are not easy to treat and resolve. Best to get ahead of these problems before they even start.

To prevent paint problems in homes in high humidity areas, follow this recommended waterproofing and painting system:

Exterior Surfaces

1.  For waterproofing, use Boysen Plexibond

Homes in High Humidity Areas: Waterproofing and Painting Guide | MyBoysen

Moisture on concrete walls is the enemy of houses in high humidity areas. To combat this, consider Boysen Plexibond for the exterior surfaces of your home. Boysen Plexibond is the go-to product for waterproofing. It provides excellent water resistance and eliminates water seepage.

It does this by forming a seamless, non-porous, impenetrable layer that disperses any water upon contact which makes it ideal for positive side waterproofing. (Positive side waterproofing means applying waterproofing measures on the side of the wall that comes in direct contact with moisture or water.) It is also resistant to weathering which can then prolong the service life of light building materials such as marine plywood and fiber cement boards.

Mixed with Portland cement, Boysen Plexibond is applied on bare concrete that has not been previously painted.

2. As an exterior paint, use Boysen Elasti-kote

Temperature changes causes concrete to expand and contract. In places like Baguio and Tagaytay where the temperature ranges are wider, the concrete walls of a house are subjected to more expansion and contraction. Because of this, you will need paint that is more “flexible” and will be able to withstand it.

Boysen Elasti-kote is an elastomeric wall paint that has excellent elongation and tensile strength. So yes, to put it in simpler terms, it is “flexible” enough to tolerate the expansion and contraction. It is also specially formulated to bridge hairline cracks and has good water resistance and excellent weatherability.

Interior Surfaces

1. As a skimcoat, use Konstrukt Permaplast K-201 High Performance Acrylic Skimcoat

Konstrukt Permaplast K-201 High Performance Acrylic Skimcoat is applied on concrete walls to correct imperfections that are 2mm to 3mm thick. It can smoothen a cement finish and repair surface defects like cracks, gaps, and honeycombs. It can also improve water resistance and minimize cracking which is what you want for a home in an area with high humidity.

This product is mixed with sifted cement at a 1:1 ratio and applied as a thin layer on new concrete using a steel trowel. The surface should have also already been cured for 14 to 28 days prior to application.

2.  As a primer, use Boysen Acrytex Primer or Boysen Acrytex Sealer

After your skimcoat, Boysen experts recommend priming with Acrytex Primer or Acrytex Sealer. The Permaplast K-201 skimcoat and Acrytex Primer/Sealer together create a wall that is not only aesthetically pleasing because of its smooth finish but also highly water resistant. It makes for a rigid waterproofing system indoors that works well in high humid areas.

Boysen Acrytex Primer creates a seamless, non-porous, watertight film that repels water and prevents seepage. It serves as a moisture sealant for concrete and a stain inhibitor for wood too. Boysen Acrytex Sealer is also a good alternative as it is specifically intended for concrete surfaces situated in humid and cold climates. You can opt to use both of these products on your walls. If so, apply Acrytex Sealer first then follow with Acytex Primer.

You’ll be able to find additional details on Boysen Primers, including the Acyrtex Primer, here. More technical information on Boysen Acrytex products can be found at Boysen.com.ph and on the Boysen App.

3. As an interior paint, pick from Boysen Permacoat Latex, Boysen Healthy Home, and Virtuoso Silk Touch

After you’ve prepared your walls with the Boysen Acrytex Sealer or Boysen Acrytex Primer, you can choose from any of the top choice Boysen interior paints, namely: Boysen Permacoat Latex, Boysen Healthy Home, and Virtuoso Silk Touch. (Note that if you only use Acrytex Sealer, you will still need to apply a primer before your topcoat.)

Because you’ve properly primed your walls to be water repellent, you have more freedom to choose the topcoat. Any of the interior paints mentioned above is a good choice.

You can find more info on the interior paints above collated in one blog post here. Each has its own unique merits (such as antibacterial properties) and qualities (such as whether the finish is semi-floss or matte) so be sure to pick the one that suits your preference best.
