So I was able to get confirmation on an answer from a local building inspector. As per Wisconsin Administrative Code SPS 321.15(2)(f) (f) Deck footings. Decks attached to dwellings and detached decks which serve an exit shall be supported on a structural system designed to transmit and safely distribute the loads to the soil. Footings shall be sized to ...

There are lots of ways to attach beams to posts, and you don't necessarily need purpose-built brackets. Miter your beams so that they come together at an appropriate bisection of the post top, and use whatever means is convenient to keep them positioned... dowels, angled screws, etc. In the case shown in the second image, I'd be inclined to use a skewed ...

Looks like data entry error to me. The values were reversed for several rows at some point. Considering that they spelled 'fir' as 'fire' in one case, one can assume that accuracy was not a high priority here. That's not a flush beam, either, nor is '2x8' a 'length'.

Yes, PVC conduit is nice stuff. Make sure to keep water from entering it, or it'll just turn into a swimming pool. You'll be using single wires in conduit, just like most commercial buildings. You need wire marked for wet locations. There are many grades of wire, but what I find on store shelves is THHN or THWN - the latter has the "W" wet rating. The ...

I fought with degradation of stain every year. When I painted the entire board, sealed it, I gained an extra year before the moisture compromised it.

According to your link, they sell this strictly at Lowes in Canada. I'm assuming you're not Canadian as you're using the .com instead of the .ca link for Lowes: https://www.lowes.ca/exterior-stain/olympic-378-l-wood-protector-toner-stain-and-sealant_g1346222.html?searchTerm=Olympic-Wood-Protector-Honey-Gold-Toner-Exterior In terms of mixing, don't. You'll ...

You can use any conduit material for this application. EMT will be cheaper than PVC, in my experience, but use whatever makes you happy. You MUST use an exterior (wet location) wire. Any exterior conduit is by definition a wet location. A VERY common thing we see here is folks trying to run NM in exterior conduit, which is a violation, since NM is not ...

PVC conduit is A-OK for burial -- in fact, it's often a superior choice in burial apps because it won't rust out or otherwise degrade in the underground environment, unlike ordinary steel conduit. PVC conduit is also fine outdoors provided it is marked/specified as sunlight resistant -- although this isn't a concern in an under the deck application as yours. ...

The Square Buff Floor Sander is a big version of a palm sander. In other words, you attach a piece of sanding paper and the machine shakes it in some pattern. The Floor Sander is a big version of a belt sander. Unlike a belt sander (where the sand paper comes as strips with the ends glued) the large version just takes an ordinary rectangular sheet of ...

The cans themselves are not wet rated. You should install a fixture that is. Such as a strip light that is sealed and gasketed. Something rated for outdoors. Good luck!

For anyone in the future, in most areas with not insignificant snowfall this is not code. Upwards of 6" of clearance above ground level (grade) is required to minimize moisture rot, specifically, after the buildup beam (min 5.5"), joist structure (min 3.5"), and boards (min 1") and variance (~.5"). Your deck will fall at a minimum of 16.5" from grade (the ...

I have had some experience with coatings and solvents over the years, and two weeks ago during a 90F June heat spell I recoated my small redwood entry deck with one coat of "deck finish" from the local hardware store. I had replaced the steps with new redwood and they dried well with the one coat, so I added a second - not heavy, and it dried well, also. The ...

You could also try to darken or lighten the stain slightly. If it has been weathered then the color will have changed. stain a very small patch close to the stain portion of the deck. Darken or lighten the stain to match as close as you can from there. Most of the time you can simply put a little darker stain (i.e. dark walnut.) And to lighten it you can ...

I would stain the rest of the deck, let it dry fully, and stain the entire deck again. The variation should be minimal at that point.

I think a bigger issue than paint sealing moisture out of the screws is whether or not the screws in question are made of a material compatible with your deck framing. Pressure treated lumber (which your deck is hopefully constructed with) has a tendency to corrode just about anything you put in it, unless the fasteners are stainless steel, or have a ...

What could go wrong? The concrete pavers are slightly porous and will wick water every time it rains. This will keep water against the wood deck boards for much longer than normal and will shorten the life of the wood. So, less sealing but shorter deck life. I would find a good oil based sealer like tung or timber oil that will last for more than one ...

As requested, composite really needs the tighter spacing. It will sag and feel really spongy at 24".

As requested,,,,It is hard to say how deep to dig down. When houses are built the contractor levels the ground and fills in shallow spots (much of the time). The trick is to dig down below the top soil it may be deeper. I usually find 6-8" gets me below the top soil but there have been a few that were closer to 18". I back fill the hole with crushed quarry ...

Look like I found my own answer here: trex.com/trex/groups/content/documents/document/trex_004114.pdf as basically you could have 2.5 overhang and you can screw from bottom up at 45 degree angle. Interesting! If you the deck is totally not parallel and has more than 3 inches offset. I imagine the easy way to fix would be to "double" the trim joists with ...

Indeed, sistered boards may provide an area that is vulerable to moisture buildup and decay. However, in practice/experience the effect is not very pronounced. If I was concerned about it because of general moisture in the area, then I would use zinc paint between the joists to help reduce any mold issues. If spacing is preferred, then I'd recommend a 1/8" ...

Simpson Strong Tie makes an "Adjustable Truss Hanger" THA-Series.

Those are simple L-angle joist hangers. I'm not sure if it's appropriate to use them like that, though... especially if you plan to use the stringer to support something (other than itself). In other words, the ground-support should be directly supporting the stringer and the joists should be resting on the stringer- unless you will not be using the ...

In case you're dealing with decay .... Sistering two joists is usually done to support a heavier load than the one for which the structure was originally built. On the other hand, if an existing joist is decaying, then there is no need to sister a second joist of the same dimensions because the new joist by itself will be sufficient. Just replace the ...

no - the LSU hangers sit over the end of a square cut joist or rafter. they wont work if you cut them on an angle.

Those are not the correct nails, period. A "Box" nail is thinner than a "Common" nail, and unsuitable for framing. Per chart found here, 0.162" .vs. 0.135" which is 144% more steel in the common nail (review geometry if you don't get that.) Box nails, being thinner, are easier to bend, as well; but predrilling can help if you are not a skilled framer - ...

For framing a deck where you cannot see the nails, an external product is desired. A galvanized framing nail will not rust where a standard framing nail will rust and potentially eventually fail. For areas you CAN see, I prefer screws, as they won't pull out and can be screwed flush. It may also be worth it to rent a compressor and framing nailer for a ...

cedar is soft, grit not critical, I would use 150

Yes it's a terrible and dangerous idea to mount it on a wood deck. The muffler is within six to 8 inches of base and it will, under the wrong circumstances, set the deck on fire. Check the install manual. It will require fireproof base, preferably concrete.

when you are building things 24 feet up and asking these kind of questions, it should be self evident you need to hire someone to do it for you or at the very least handle the technical design and ensure that what gets built is inspected and checked to make sure it matches the design specifications. do yourself and any of your future guests and neighbours ...
