James Hardie Siding Maintenance

Part of maintaining your new James Hardie siding is following the proper procedures for care and maintenance. Fiber cement siding is very low maintenance, but like any part of your home, should be cleaned and attended to on a regular basis. Keeping your siding clean and making repairs to damaged caulking, cracks, or chips helps to ensure that your siding stays in good condition and keeps your home looking beautiful. If you are ever in doubt about how to address a certain maintenance issue, it’s always a good idea to refer to the manufacturer’s recommendations or contact a local James Hardie siding contractor like Denver’s Scottish Home Improvements.

Repainting/Repairs

If you believe that your James Hardie ColorPlus siding may need repainting, you might want to consider washing it first. Most of the time, washing your siding helps to remove dust and debris which can rejuvenate its appearance. However, if painting or repairs are desired, it’s best to stick to the following tips and advice:

• Repainting over the top of ColorPlus products before the 15 year warranty is expired will void the warranty. If repainting is still desired, homeowners should refer to the Technical Bulletin S-100 on the James Hardie website.
• Use ColorPlus touch up to repair any scratches or damage caused during installation if the area is smaller than the size of a dime.
• Do not use stains on PrimePlus products.
• For PrimePlus products, check the manufacturer’s recommendations for repairs and repainting.
• Keep deicing salts away from James Hardie products. Use sand or gravel instead as a substitute.
• Repair minor surface damage using a cementitious patching compound that’s compatible with fiber cement.
