Problems of Masonite Sidings:

Even after possessing so many advantages, Masonite developed some problems of its own. After a few years of its introduction into the market, the users identified the issues. These problems somehow led to a decline in its purchase too for some time. The commonly reported problems were :

1. Rotting

Buckling, swelling, and rotting are all common issues with masonite siding. The moisture infiltration causes this into the sidings due to various reasons such as cracks. The wood chips and resins cannot remain intact once they get wet. The water makes the wood swell, which causes the sidings to warp and buckle.

As the wood remains wet for a long time, it begins to rot, this makes the board decay, and it starts getting soft. The worst part is this cannot be repaired in any way. Rotting of siding directly means that you need to replace it.

2. Blistering

Another widespread issue with Masonite is Blistering. Even though Masonite requires less maintenance than wood, the paint is not a permanent finish. When this paint is exposed to moisture or heat, it starts to blister or bubble off. The blistering can also be caused by the insects eating through the siding.

Due to this, the siding starts looking unattractive, but the moisture becomes more susceptible to reach beneath the paint. This directly leads to two losses together. To prevent this, the user will have to stay highly attentive to water coming in contact with siding in any way.

3. Mold and Mildew

When the moisture comes in contact with masonite sidings, it doesn’t come off quickly. It damages the sidings to the very core. The board starts getting damp, which becomes the perfect invitation to mold and mildew.

This problem might stay as low as leaving stains on the exterior of your house. This is not a minor problem because nobody wants an unattractive home when they have spent all of their income to build it. The worst that can happen is, the mold might start to grow deeper. This will infiltrate the whole interior of your house. Both the cases are alarming and problematic.

4. Insect Issues

Even though Masonite is not exactly a solid wood product, but it’s still made from wood. This makes it vulnerable to insect problems. Through the years, and due to exposure to moisture, the Masonite might begin to soften. This soft surface becomes attractive to some insects such as termites and carpenter ants.

These insects decay and compromise the integrity of the siding board. This is another non-repairable problem. You’ll eventually need to replace the siding.

5. Discoloration

Some users stay extra attentive towards the blisters and scraping. Even if you are one of them, you’ll not be able to prevent discoloration. It is something that is Masonite’s feature. Discoloration comes to it.

Hence, no matter how much you keep painting it, again and again, this will happen. Discoloration may be caused by resin or mold and mildew. Even if the paint is new, the stains will seep out of it.
