How To Repair Top Of Post That Is Rotted

Subject field: Repairing Rot on Fence Post Tops

Date: Monday, September 10, 2022

Hello,

I am in the process of overhauling a 20 twelvemonth onetime wooden debate and accept a number of questions that I'm hoping you can help me with.

I am replacing all of the eight′ contend panels (52 panels total) but am hoping to proceed most (if not all) of the 6x6 pressure treated fir posts. And so far, of 11 panels torn downwardly, all of the panel posts appear to be structurally sound only several of them take dry rot in the caps of the post and at to the lowest degree 2 have substantial rot to a depth of 3–v″ into the top of the post. (delight run across pictures for reference) I'1000 bold, based on the tutorial on your spider web site for Beam and Joist Rot, that a combination treatment of CPES* and Fill up-It* (possibly with sawdust added) would be your recommended solution for this type of outcome just I am hoping you lot can ostend that before I caput down that path.

CPES* would definitely exist the first production to use. The Fill-It* doesn't need any sawdust. And while some of this production would be useful, you would also likely want the Layup & Laminating Resin* (LLR) which can be used plain for smaller cracks, or mixed with sawdust for larger voids, both of which appear in your images.

I have a couple of other argue project related questions that I'm besides hoping you tin reply.

one. Volition the treatment and fill of the posts give it an equivalent level of structural integrity and as the original wood? And, is "yep", what is the expected lifetime of this treatment?

Epoxies, ours included, are stronger than the forest itself. Used properly, the structural strength should be significant, at least approaching the original. Possibly exceeding, but difficult to quantify without destructive testing. Basically the lifetime expectancy is indefinite, or at least longer than the wood - keeping in mind that epoxies are not UV stable and sunlight volition slowly intermission them down, paint or UV coatings will protect them.

2. For a total of 52 6x6″ fence posts, all of which will arguably need to at to the lowest degree be sealed and at least 50% that will need some filler, can you brand an educated guess as to what quantity of handling chemicals I would need to purchase from your company to consummate this task?

My best educated judge would be one pint of CPES*, and one quart of fillers per mail service, for the mail illustrated in the image given. The fillers would be some combination of the Fill-Information technology* and LLR*/sawdust.

3. Some of the posts likewise have split up cracks downwards the side. (see second picture for reference) Is in that location whatever reason I should consider treating these cracks equally well?

In one case the ends have been repaired, moisture getting into the cracks on the side will not significantly increment the moisture content of the wood, so there is non a huge need to treat and seal them. I would coat the within with CPES* an leave it at that.

4. For a task this big I am hoping there are some tools or techniques that would make the task more than efficient; e.g., a caulking gun or something like to dispense both the sealant and filler. What would y'all recommend?

For the CPES*, I would just castor/pour information technology on the ends. For the vertical cracks, a pump up garden sprayer works well, only would be glued close, and then that is a one fourth dimension utilise applicator.

For the Fill up-It*, I would just button it into the cracks on the side near the height with a putty knife, after the CPES* has been applied and cured. In one case the Fill-Information technology* cures, it will comprise the LLR*, which can be poured in. Initially, un-thickened for for smaller cracks, so thickened with sawdust for the larger, final fills.

five. Lastly, do you have any recommendations on what I should treat the new fir and cedar fence panels with for NW conditions related issues? (I typically default to Miller Paint for wood treatment products on my deck)

CPES* applied to critical areas is excellent for extending the life of exterior wood. End grain, fastener holes, and whatsoever identify where ii pieces of woods impact are the critical areas. After that, y'all can glaze the remainder with any pleases you. Keep in mind, that CPES* practical only in certain areas may crusade the subsequent stain to take two dissimilar looks. Please test earlier yous commit to anything.

Thanks very much for your time and advice.
