If you built a deck three weeks ago with pressure treated wood using bright framing nails and they are already rusting on the top how long will they last?

Ouch, tough mistake. What you should have used was those high tech deck screws. If you ever need to replace a board it is a lot easier. The nails you used were not stainless steel and what that means is that they will stain. They will last a long time but will continue to rust. At this point my advice is to seal the whole deck with a water seal and try to prevent rust. I have done things like that and it is one of those things. Luckily, I learn from most of my mistakes. To fix it you have to disassemble the deck, remove the nails, put in the screws. You have to decide if you can put up with the rust. Good luck VBD If the pressure treated lumber you used was treated with an "ACQ" formulation, or a "CBA-A" or "CA-B" formulation, your nails will not last long at all. The new wood treatment formulations introduced in the past couple of years to replace the "CCA" treatment (which contained chromated copper and arsenic), are heavy to copper, which is corrosive to many dissimilar metals. Your deck needs to be fastened with stainless steels screws or ring shank nails (very expensive), copper nails (hard to locate and expensive), epoxy coated deck screws, or hot-dipped galvanized nails with a galvanized rating of G-185 (your lumber yard should be able to get them for you if they're not in stock). Personally, I prefer the coated deck screws...they're a little spendy, but your deck planks will stay put. I use a brand called "Trapeze" which were designed for composite deck planks such as "Trex" but work very well with other decking materials.

It is typical to use pressure treated "2 x 4" for tub support framing.

Not, as of yet, but you could try it. rusting can only be prevented or treated thereafter.

See your doctor immediately, unless you are already being treated for high blood pressure.

Remove rotted material from the wall and re-frame it using pressure treated lumber or a foam or tar paper membrane between the bottom plate and the concrete.

cover in oil, paint, grease or plastic. or galvanise it

A pressure treated with those measurements will be about 350 lbs. That is more than the common standard pressure treated measurements.

There are four different types of framing lumber. The common framing lumber are Spruce-Pine-Fir, Structural Southern Yellow Pine, Machine Stress Rated Lumber, Treated Southern Yellow Pine #2 and Better, and Bluwood.

Preservatively-treated (pressure-treated) wood does not meet the standard, unless the wood was heat-treated and stamped HT prior to preservative treatment.

Wolmanized Wood is a brand of pressure treated wood.

Pressure treated wood is soaked in a special chemical to prevent rotting. Pressure treated wood products have "holes" in them, so the liquid can be readily absorbed for optimal saturation.

If the pressure treatment is identical, theoretically they should perform equally.

Yes in fact Pressure treated wood floats quite well do to the buoyancy in the grains.

Metals are prevented from rusting by providing a coating on the surface of the metal to stop the metal from mixing with oxygen and H2O in the air. Please do not copy this word for word. I am handing this in for a report. Thanks!

Pressure treated wood can last up to 20 years or more and most pressured treated wood sold in stores such as Home Depot offer a limited lifetime warranty.

The surface of steel can be colored by plating, paint, rusting or chemical treatment- but the metal retains it's silvery color. BTW, steel firearms are treated to darken their color- "bluing"- and it is a form of controlled rusting.

If you want to prevent a screw from rusting, you should buy the appropriate type of screw. You can get stainless steel ones or specially coated ones for pressure-treated lumber. Your local hardware store has a wide assortment of screws, and will have the right kind for what you're doing. They might even help you find the right kind for your application. Don't apply a coating of nail polish to prevent rusting. It's simply not appropriate. It won't last and it won't work.

You can use untreated as long as you have a treated sill plate. Untreated wood should not touch the concrete.

Pressure treated wood is not good to burn... in could have chemicals in it. If you need to burn it, burn it where people wont breath it in.

User Avatar

It doesn't need to be treated. It is resistant to fungus without treatment.

User Avatar

There are chemical used in the pressure treatment that may be harmful.

Older pressure treated lumber known as CCA was treated with 3 substances, Chrome, Copper, and Arsenic. Newer treated lumber intended for consumer contact is now treated with different chemicals, such as copper/boron. Lumber NOT intended for consumer contact, such as buried or submerged lumber may still be CCA treated. PS- it is not a good idea to burn ANY treated lumber. If it kills bugs and fungi, it is likely not real good for you, either.

Hypertension, high blood pressure, is typically treated by a low fat low sodium diet and potentially medication such as beta blockers or diuretics.

Yes, you can stain pressure treated wood as long as it has had several months to dry out.
