If you have wood siding, it is recommended that you repaint it every three to seven years or stain it every four years. For stucco facades, you should schedule a coat of paint every six years. Cement board siding, like hardboard, can last 10 to 15 years before needing repainting.
Masonite is a brand of hardboard wall cladding made from compressed wood fibers. Like all wood paneling products, Masonite requires periodic painting to maintain its appearance.
The lifespan of masonite
If masonite is caulked well and regularly it can be expected to last more than 20 years without problems. Damage occurs when proper maintenance is not followed. If you own a masonite clad home, inspect it regularly.
The spaces between Masonite cladding and along their edges should always be sealed. Improper caulking can result in moisture damage and speed up fairing replacement. Inspect your grout regularly and replace as necessary to extend the life of your Masonite siding.
Painting Masonite™ siding
New builds do not normally have paint thickness requirements, just enough to get through and allow the home to be sold and occupied. Most paint manufacturers recommend exterior coats consisting of at least 9 mills dry, while wet paint coats would require 13-16 mills
A word of caution when cleaning your home: If your home’s exterior is masonite or other hardboard, do not proceed with the pressure washing. The intense pressure of the pressure washer can damage the fairing; Opt for the old stand-by garden hose and some household bleach to get the job done.

It is currently still available as “hardboard”, although most people still refer to it as masonite. Regardless of what it’s called, the material has many common issues that often lead to replacement.
Inspect the outside of the home for moisture problems. One area that often rots and serves as a haven for termites is masonite siding.
Masonite composite hardboard has a natural resistance to moisture. When installing Masonite, the area of hardboard penetrated by a fastener can absorb moisture. Moisture causes the area around the penetration to expand. This expansion causes the fibers around the penetration to loosen and weaken the masonite.
Also, Masonite siding requires a primer before painting. A primer suitable for Masonite is required and the fairing must be completely dry before the top coat is applied.
Paintability of Masonite or hardboard varies by manufacturer and manufacturing process, even if the hardboard is of the same grade. Painting masonite requires the use of basic painting techniques for a durable finish.
After settling a dispute over defective exterior panels, Masonite improved its product. You can seal and paint the siding if it’s in decent condition but you should replace rotted masonite siding.
