Masonite is a type of engineered wood that is made from wood fibers that are combined with resin.
The resulting product is very strong and can be used for a variety of applications, including flooring, cabinetry, and doors.
Masonite is also very easy to work with and can be cut, drilled, and shaped to fit a variety of different needs including exterior home siding.
However, if you use masonite for the siding it’s important to keep it dry and to apply a protective finish to ensure that it stays looking good for many years.
The type of paint you can use on masonite siding is generally acrylic latex paint which should be painted over exterior alkyd primer once it has been dried completely.
Below we will go over a few important points to keep in mind when painting over masonite siding.
So get ready to transform your siding with the fresh modern paint colors!
How to Paint Masonite Siding – Step by Step
Regardless of which color you choose, painting your masonite siding is a great way to add some style and personality to your outdoor space.
Before you get started make sure to wear a dust mask and protect your eyes with safety glasses.
Then follow these steps…
Step 1- Spread drop cloths
Use drop cloths or tarps around the area you’ll be working in to protect your landscaping from paint drips.
If you don’t have one in your home, these are available in various materials such as plastic and canvas.
So depending on your requirement you can get one from the market.
Step 2- Make any necessary repairs to the siding
Before you paint, carefully inspect your masonite siding for any cracks or damage that may need to be repaired.
You may need to use a ladder to reach higher sections of siding at times. So, be cautious to avoid falls.
Step 3- Remove existing paint
Use a sander or wire brush to remove any existing paint so that the new coat of paint will adhere properly.
Be sure to work gently to avoid any damage to the Masonite. And also clean up all the sanded dust and the old dried paint chips using a vacuum.
Step 4- Apply a layer of exterior alkyd primer
Use an exterior grade alkyd primer to help ensure that your siding is properly sealed and ready for paint.
Be sure to follow the instructions on your primer carefully and apply multiple thin layers using a paint roller rather than just one thick layer.
You will need to pay particular attention to the siding’s edges and bottoms, as they tend to absorb water and paint more readily. Use a brush to clean out tiny places.
Allow the primer to dry completely before moving on to the next step.
Step 5- Apply acrylic latex paint to the siding
Apply a coat of acrylic latex paint over the dried primer using a clean roller.
For painting in tight spaces and corners you may need to use a small brush, so keep one handy near you.
Wait for the first coat to dry completely before applying a second layer using the same procedures.
Step 6- To finish off the look apply a few coats of clear polyurethane
The final step is to add several thin layers of varnish to protect your masonite siding from moisture and weathering.
And that’s it! You are now ready to enjoy your fresh new masonite siding.
Tips and Warnings
Consider using a paint sprayer (rather than a paint roller) to apply paint, primer, and varnish to a large home.
For the best results with Masonite, roll over the paint after it has been sprayed to ensure that it is evenly distributed throughout the surface.
This technique is known as “back-rolling,” and it’s great when you need to cover uneven or roughly-textured surfaces.
Most importantly BEWARE OF LEAD PAINT if your home was built before 1978.
If you suspect there may be lead-painted masonite siding in your house, buy a lead paint test kit from your local hardware store and hire a professional contractor to safely remove and dispose of any lead paint.
Overall, masonite is a very versatile product that can be used for a variety of purposes including siding.
It is also relatively easy to paint over provided you use the right paint products in the right way.
So don’t wait any longer – start exploring your options and find the perfect color for your old masonite siding now!
