INSTALLATION OF HARDIE BOARD SIDING: A STEP-BY-STEP GUIDE
For Hardie boards to last long and look beautiful, these boards must be installed correctly. If not installed properly, they can look uneven on the walls and are more susceptible to damage. Here is a step-to-step guide to ensure a smooth installation process:
1. Framing Requirement
Hardie boards can be installed over braced wood or steel studs, 20 gauge minimum to 16 gauge maximum, spaced a maximum of 24 inches or placed directly to a minimum 7/16 in thick OSB sheathing.
2. Remove the Old Siding
If you had sidings previously installed, it is best to scrape them off before installing the new board. However, you can also use the existing siding as the base, but only if they are in good condition. Installing new Hardie boards on old, rusted, and damaged sidings could cause several structural problems in the board.
2. Sheath the Wall
To install your sidings properly, the first step requires you to sheath the walls with foam or plywood and then cover them with house wrap. Doing so makes marking the locations of studs easier.
3. Use Circular Saw
Cutting saw is often a popular choice to evenly trim the sidings. The other cutting tools you can use include jigsaw, pneumatic shear, carbide score, and snap knife. The cutting saw produces a lot of dust, and so it’s always better to use a cutting saw with a dust collector, and make sure to wear a mask to avoid inhaling silica dust.
4. Fasten the Siding
Using the right nail is important to fasten your Hardie boards. There are many nails available, including corrosion-resistant screws, stainless steel, and hot-dipped galvanized nails. To hold your boards securely, you can either nail them by hand or use a pneumatic nail for more efficiency.
5. Install the Trim
To begin installing the Hardie boards, place the trim in the corners of the wall. The corners should be at least ¼” thicker than two stacked pieces of siding. The trim can be made from vinyl, wood, or fiber cement products.
6. Install the Siding
Hardie boards should be at least 6″ above the grade level of the house. There should also be a 1″ -2″ gap between horizontal surfaces like steps, decks, or adjacent roofs. Use an overlap gauge for support if you are working alone. Install the siding boards and butt the courses tightly together. Make sure you stagger the butt joints so they don’t lay on top of each other. Then, leave about a ⅛” gap between the corner trim and siding.
After the installation, Hardie boards should be painted as soon as possible. Keeping the boards clean and dry before painting them is important to avoid paint ripping later.
Common Mistakes with Hardie Board Installation
Hardie board installation is a difficult task, and the job becomes more difficult if you are not aware of the installation protocols. To ensure that these mistakes don’t happen, avoid the following mistakes before and after installing the Hardie board.
1. Storage errors
The storage instructions for Hardie boards are simple. Make sure to keep them indoors or under a cover to avoid getting them wet, and secondly, place them flat on level ground to keep them away from the ground moisture. Wrongly storing the Hardie boards can damage their quality and overall efficiency after being installed.
2. Wrong Touch-Ups
For Hardie boards to look beautiful, painting them in the right color and good quality paint is important. Due to its curves and wavy pattern, Hardie boards can be difficult to paint. To avoid them from looking ugly and uneven, using the right amount of paint is also crucial. Using too much paint will end up giving the boards a splotchy look. Unfortunately, the only way to fix the boards would be to take off the paint and repaint the entire exterior
3. Mistakes With Joint Placement
Hardie board sidings are 12 feet long and must be joined with the wall. Wrongly placing the joints can pose a threat to the overall structure of the sidings. Joining the Hardie boards is quite easy, but there are a number of ways you can go wrong with the joint placement:
No gap should be left between the boards when being installed. Leaving space for expansion can create an unnecessary gap between the boards which can cause squeaky noises or cause the boards to break.
It is recommended that a 6″ wide piece of weather-resistive is placed between the joints of the sidings. It helps prevent water from getting through the board and damaging the internal walls. Failing to secure the joints can decrease the durability of the Hardie board. Color-matched, silver sheets are the best option to prevent the boards from looking ugly.
All joints must be placed on a stud unless a minimum of 7/16″ wood structural paneling is available for sheathing. If joints are not properly placed, it can cause clusters, steps, and zipper patterns to appear on the surface of the wall. .
4. Not Enough Fasteners
For boards to stay in place for years, they need to be fastened to the studs with nails and screws in a familiar fashion. If not properly secured, the Hardie board can flex slightly by the pressure of the wind, damaging the overall structure of the exterior.
5. Nailing High
Using a pneumatic nailer makes the job fast, but the only downside is that if going too fast with this tool, they can lose the nails track and pin the nails diagonally. All the nails must be placed in a line. Bolting the nails at a height runs the risk of the board becoming loose as it pushes against the harsh wind. However, if you placed them lower, you could see their head poking through the board, ruining the look of the wall.
6. Spacing Issues
Hardie boards require a minimum 2″ gap from all hard surfaces and at least 8″ from any soft surfaces. If these boards are installed too close to the wall, there is a chance the paint may come in contact with the water in the wall and so will start to peel and bubble.
7. Not Removing the Cut Dust
Hardie boards are made of fabric cement. Cutting and installing these boards creates a lot of silica dust, which is toxic if inhaled. It is always advised to use a mask, and a dust collector saw to avoid spreading the dust. It is also essential to wipe off the silica dust from the boards before painting them. If not cleaned properly, the dust can settle and stick to the paint, and the longer it sits on the paint, the tougher it’s going to be to remove it.
8. Not Using the Right Corrosives Resistant
Hardie board can withstand the harsh weather, but even the stainless steel nails and screws are bound to rust after a few years. Not many people take this into account when installing the Hardie board. Not using good corrosive resistance can damage the nails and, ultimately, your board sidings.
How to Maintain the Quality of Hardie Board
The extent and nature of maintenance will depend on the geographical location and exposure of the building. It is recommended that basic normal maintenance tasks shall include but not be limited to:
- Washing down exterior surfaces every 6-12 months
- Periodic inspections should be made to ensure fasteners adequately secure the panels to the framing.
- Re-applying of exterior protective finishes.
- Maintaining the exterior envelope and connections, including joints, penetrations, flashings, and sealants that may provide a means of moisture entry beyond the exterior cladding.
- Cleaning out gutters, blocked pipes, and overflows as required.
- Pruning back vegetation that is close to or touching the building.
