ColorPlus Technology Caulking, Touch-up & Laminate
When repainting ColorPlus products, James Hardie recommends the following regarding surface preparation and topcoat application:
• Ensure the surface is clean, dry, and free of any dust, dirt, or mildew
• Repriming is normally not necessary
• 100% acrylic topcoats are recommended
• DO NOT use stain, oil/alkyd base paint, or powder coating on James Hardie Products.
• Apply finish coat in accordance with paint manufacturers written instructions regarding coverage, application methods, and application temperature
• DO NOT caulk nail heads when using ColorPlus products, refer to the ColorPlus touch-up section
Cut Edge Treatment
Caulk, paint or prime all field cut edges. James Hardie touch-up kits are required to
touch-up ColorPlus products.
• Care should be taken when handling and cutting James Hardie ColorPlus products. During installation use a wet soft cloth or soft brush to gently wipe off any
residue or construction dust left on the product, then rinse with a garden hose.
• A finish nail is required for installing 4/4 and 5/4 HardieTrim boards.
• Touch up nicks, scrapes and nail heads using the ColorPlus Technology touch-up applicator. Touch-up should be used sparingly.
If large areas require touch-up, replace the damaged area with new HardieTrim board with ColorPlus Technology.
• Laminate sheet must be removed immediately after installation. Nail head touch-up can be done before or after removal of the laminate sheet when using finish
nails. The preferred method is to touch-up while the laminate sheet is in place. Remove the laminate sheet before paint dries.
• Terminate non-factory cut edges into trim where possible, and caulk. Color matched caulks are available from your ColorPlus product dealer.
• Treat all other non-factory cut edges using the ColorPlus Technology edge coaters, available from your ColorPlus product dealer.
Note: James Hardie does not warrant the usage of third party touch-up or paints used as touch-up on James Hardie ColorPlus products.
Problems with appearance or performance arising from use of third party touch-up paints or paints used as touch-up that are not James Hardie touch-up, will not
be covered under the James Hardie ColorPlus Limited Finish Warranty.
