A well maintained deck add charm and beauty to your house. Beside, it’s your connection to the outdoor. Unfortunately, the continues exposure to the sun, rain, snow and temperature changes, can negatively affect it. First, ultraviolet radiation (UV) from the sun breaks down surface fibers and lignin, causing graying and surface erosion.Water from moisture settles in the open cellular layers wherever there is a break and promotes rotting.
Temperature change especially where water has penetrated the inner cellular layers, accelerates cellular deterioration.
Microorganisms-Mold and mildew are particularly common trouble makers. Green, black, or gray discoloration is caused by mildew colonization.
Particulate-Particulate matter comes in many forms such as dirt, soot, pollen, and food. These organic particulates provide nutrients for microbial growth and accelerate wood deterioration.
stains may result from iron in nails or other hardware darkening the surface. Lime found in mortar mixes may leach from adjacent brick or stonework and coat the deck surface causing a variety of staining.
The following steps should help you restore your deck properly:
1- if your deck is brand new, use a high quality deck cleaner/brightener. This will eliminate mill glaze and       provide  a clean surface for deck sealer.
2- If your deck had been stained, you need to use stain stripper,  or sand deck to bare wood.
3- Apply  oxalic acid, then rinse your deck.
4- Apply stain water proofing.
5- You should follow manufacture recommendation for each product.
Note: if your deck has nails, make sure you countersink all of them.
