Should I use 4x4 or 6x6 deck posts?

A short 4x4 can carry an awfully big load, and many deck builders use 6x6 posts as a standard, regardless of the height or load of the deck. Though the height of a deck is often questioned only in regard to the requirement for guards, it is a factor in determining the height or “span” of the posts.

Will bleach stop wood rot?

To treat decay fungi, first eliminate the source of moisture (unless its dry rot). A dilute bleach spray will kill molds and mildew. If decay is extensive, replace the decayed wood. However, if lumber is allowed to soak in the wood preservative, it works even better.

Will kilz stop wood rot?

You really can't "stop" dry rot - once the wood is rotted, that's it. You could alternatively add some metal braces to the wood that's intact. Other thoughts would be to "seal" the rotted parts with Kilz, primer and some oil paint.

(30- to 46-cm) sidelights. Double columns spaced 7 to 8 feet (2.1 to 2.4 meters) apart frame the entrance, which is 5 to 6 ft. (1.5 to 1.8 m) wide. Two more outset columns spaced slightly less far apart than the center width complete the porch's breadth.

Does paint stop wood from rotting?

Coatings that form a moisture-impervious film are effective in preventing decay if the seal where two pieces of wood are joined is kept intact. A well-maintained film of paint over the wood and good paint seals in the joints shed water, thus protecting wood by keeping it dry.
