Hardboard Siding Installation: 6 Tips

A hardboard siding is an engineered product that offers many different benefits. Less expensive than hardwood, hardboard sidings are much similar in both design and style to most of the hardwood paneling products. Some of the specific designs of these hardboard sidings are even made to appear like the traditional board and batten style sidings. These sidings have a smooth surface due to the uniform finish. The panels of the hardboard sidings come in two main sizes: 4 X 8 and 4 X 10 feet. However, it is possible to order custom sizes for your specific needs. Here are 6 common hardboard siding installation tips and mistakes to avoid.

1. Use a Primer

Before installing the hardboard siding, make sure that you seal it or use a primer on it so that all edges are covered. This is done to prevent moisture from penetrating into the siding; this is necessary because hardboards are extremely prone to rotting due to heavy moisture exposure.

2. Leave a Gap

When you are installing hardboard sidings, never install a hardboard right along the ground. You need to make sure that the board is at least 6 inches above the ground, so that it does not come into contact with moisture and mulch. The right kind of clearance is extremely important, particularly when you are working with hardboard siding.

3. Don’t Overdrive the Nails

Do not overdrive nail heads when you are hammering nails into the siding. Drive them in only to the extent where the nails butt tightly to the siding. Since moisture absorption is a major problem with hardboard sidings, driving in the nails past the flush can expose the inside fibers that readily absorb moisture and cause rotting.

4. Paint Well

A sturdy paint job is extremely important for a siding installation. If you install a hardboard siding and do not give it a good paint job, it is most likely going to get rotten very soon. However, keep in mind that you should not use spray paint for painting hardboard sidings; this is because spraying on the paint leaves a very thin layer of it on the sidings. Instead, use a roller brush or a paintbrush so that paint is applied uniformly. Also, make sure that you apply at least two coats of paint. In a whole siding, the edges are usually uncut and therefore unpainted. To make sure that the siding does not rot due to moisture, paint all the cut and uncut edges before installation.

5. Keep the Moisture Away

When you are installing the sidings, take proper care to make sure that any sources of moisture remain as far as possible from the siding. If you have sprinklers in your front lawn or backyard, turn them away from the sidings. The sidings generally should be installed in areas where moisture cannot come in close contact with it.

6. Treat with Fungicide

Before installing the siding, treat it with a fungicide, if it does not already have the necessary treatments. This can lengthen the life of the sidings by at least 3 to 5 years.
