CARE AND MAINTENANCE — 6 — CLEANING YOUR DECK
CONSTRUCTION MATERIALS
Construction Chalk
Masonry Construction
Colored chalk used in construction for marking straight lines prior to cutting is permanent on most surfaces. Contact the
specific chalk manufacturer for a cleaning solution that may prove effective. The best advice is to avoid colored chalk.
Instead, use a workable alternative such as white chalk or baby powder.
º
Always protect decking during masonry construction. White or hazy residue from mineral deposits (efflorescence) can
leach out of stone and masonry material after water evaporates, leaving the deposits behind. Minerals from soils in
certain arid and mountainous environments can also cause a hazing affect when deposited on the deck surface.
º
To prevent this, either cover the decking surface completely and securely during the construction phase or wait to
install the decking until after masonry construction has been completed. To minimize this effect during masonry
construction, keep materials dry and allow masonry and cement to cure properly.
º
For mineral deposits left on the decking surface, periodic cleaning is required. Use mild soap or a composite decking
cleaner, and be sure to follow the label instructions carefully. Do not mix recommended cleaning products together
as harmful chemical reactions could occur. NOTE: For Symmetry
®
Decking, use a soft nylon deck brush, not a brass
bristle brush.
CHOOSE YOUR BRUSH CAREFULLY:
For stubborn or hard-to-remove stains, we recommend a soft, brass bristle brush
for all Fiberon Decking EXCEPT Symmetry Decking. Use a soft nylon deck brush
for Symmetry Decking to avoid potential scratching.
