How Do You Wrap Posts With Hardie Boards?

Wrapping posts with Hardie boards can be very tasking. It isn’t advisable to do this yourself since improper installation can void the warranty on the Hardie boards.

You can only attempt this if you’re confident in your abilities and know the warranty conditions.

To wrap your posts with Hardie boards, you’ll need the following;

  • Galvanized nails
  • Measuring tape
  • Nail gun or hammer
  • Saw
  • Work table
  • Glue

The following is a guide on how to wrap posts with Hardie boards.

#1. Measure Your Posts

Use your measuring tape to measure the dimensions of your post, including the width and height.

Stretch the measuring tape from the bottom to the top of the post to get the length.

For the width, stretch the tape from left to right of the post to measure it. Ensure that you take measurements for each post and record them.

#2. Purchase Hardie Boards

After getting the measurements, you can buy HardieTrim boards in sizes at least 3 inches more than your measurements. 

Buying larger boards is wiser so you can adjust them to the required measurements. Four boards should be enough for wrapping a column or post. 

After wrapping with Hardie boards, you’ll also need trims for the top and bottom of the posts.

If you’re capable, purchase enough boards to compensate for any errors.

#3. Making Spacers

You’ll need rectangular spacers to attach to the posts before wrapping them with Hardie planks.

For each post, you’ll need 12 spacers, which can be regular wood or Hardie boards.

Use the saw to cut the first six spacers of about 2.5cm and 2 inches in height. For the width, whatever measurement you get after measuring, add 1.5 inches to it.

These original six spacers will serve as your front and back spacers. After making them, smear glue across one side of these spacers. 

Attach these spacers to the front and back of the column’s top, center, and bottom. For the other six spacers, measure the space at the sides where you’ve fixed the first spacers.

This measurement should allow you to fit the spacers into the sides of the column. The second set of spacers will sit between the front and back spacers. 

After getting the measurements, I saw down wood to produce the spacers. Apply glue behind these spacers and attach them to the sides of the columns.

Note that you’ll make these spacers for each of the columns you want to wrap. After gluing the spacers to the column, send nails into each corner of the spacer.

#4. Attaching the Boards

Saw down the Hardie boards to the exact height of the columns. Remember that you have wider spacers.

Ensure that the width of your front and back boards corresponds with the wider spacer’s width.

You’ll also saw down boards to match the width of the thinner spacers for the sides.

Next, smear glue on the spacers on the columns to attach the boards. Pick a board and place it on the post’s front side. Make sure it hangs before letting it go. 

Grab the next board and move on to the back until you’ve wrapped an entire column with Hardie boards. Do so for the rest of the columns.

If all the sides fit, you can use the nail gun or hammer to drive nails into the boards. If there are any gaps, use caulk and fill them. 

You can trim the base and top of the column to give the posts a finished look.
