I am replacing a transom on a 17 foot wooden lapstrake. Thinking of laminating two sheets of marine plywood each 3/4 inch (one monogamy for outside, Douglas fir for inside for 1.5 inch thick transom. I have used Thixo on a stitch/glue small boat, but not for lamination and as big as the transom will be. Is Thixo the product? How applied? How tightly should sheets be clamped while Curing?
You could use Thixo but would require a few tubes. I'd recommend using the Totalboat 5:1 Epoxy kit, mix in some Silica to a mayonnaise consistency spread it on the surface and use a notched spreader to spread it out evenly. Clamp she sheets enough so that some resin squirts out but not so tight that it squirts most of it out.

can you use this without the tips and mix on a piece of card board for vey small jobs
Yes. Just ensure that both components are coming out of the cartridge at the same time. Mix very thoroughly for 1-2 minutes on the cardboard before using.

What sort of coverage can you get from a single tube - say for a 1/8" or 1/4" bead?
A 1/4" bead will do about 15 lineal feet, 1/8" will be 30 Lin Ft.

I am filling some drilled holes (above the waterline) and some small scratches/gouges (below the waterline) on a fiberglass boat. Are there any disadvantages to using TB Thixo as opposed to TB Total fair? Is Thixo harder to work into holes/scratches, or is Thixo harder to sand?
You could use either, the Thixo is a thickened epoxy and a bit harder to sand than Total Fair.

Can this be used to reattach rv delamination

I want to use thixo to bond solid wood to a beveled plywood face, so some end-grain in the ply. Usually, I wet out the ply with neat epoxy, then add my thickened epoxy. Should I still do the neat epoxy to avoid a starved joint with the Thixo?Thanks.
It would help the bond but will still work with just Thixo if you are using some mechanical fasteners also.
I am restoring a 9"diam. exterior wood column that had a rot from the base up about 42" x 4 1'2" wide between two iron straps. I have routed out the reachable rot areas to a 1/12" depth. The areas I could not reach with the router, I treated with Git-Rot. Some routed areas are uneven and before installing new wood pieces I want to prepare the surface to be flat and even to recieve the new.Q. What filler type epoxy do you recommend for applying with a putty knife to true and smooth the substrate?
Since Thixo works well on vertical sections, I would imagine it should be ideal for your application. Read the "working time" and i'd wait until it begins to set up before you begin smoothing with a putty knife. Almost certainly, you will have to sand the surface to make it smooth enough to look smooth enough to paint. But my applications, while vertical, have not required smoothing so my suggestion springs only from observing the material curing. Good product, though.
If it were mine I would cut the wood repair to fit as tight as possible. Use a similar wood species. There will be voids in the rotted area remaining. I would then use an epoxy like the Thixo and coat the surface liberally prior to installing the wood patch. use enough that it fills all voids and oozes out at the edges. Wipe off the excess. I use Thixo instead of epoxy because it seems to flex with the wood better.
THANK YOU JOHN, good advise. Roy
I would use any regular epoxy mix thickened with something like micro spheres or fine wood sanding dust...not looking for strength in this case, but easy sanding. It helps to add a little silica thickener to impart thixotropic properties, but this does add to slower sanding. Your posting says "1/12" depth, but if this means 1-1/2" you should partially fill it and let it harden and then fill to final depth. Use a medium fast hardener to avoid a scorching exotherm. When applying the final coat, cover the patch with any clear glossy polyethylene plastic sheet and then do the final smoothing by hand before it hardens.Pop any trapped bubbles with a pin and express the air. Might wrap some duct tape over the plastic and around the post. Really cuts out a lot of sanding. Poly film pulls off easily when resin is cured. Good Luck
Thank you Daniel H. Good to have backup in thinking as I thought Thixo might be the best for what I am doing.
Thixo is the product you want. Its think and will not run.
Will this work on polypropylene?
Not sure most Likely yes It's a good product dries quick to and strong
I do not think so. Epoxy does not stick to most plastics.
You will need to rough it up with heavy grit sand paper first. 60 or 80 grit will work.
I think it will try a small area first I know this is not a 100 percent answer but given the product very good chance it will. Mike.
are the thixo tube tips cleanable?
No.You need to plan your work well and/or have additional tips available. I have also dispensed both parts from cartridge without the tip and then mixed the 2 together with an applicator spatula with good results.
No not really.. You might be able to play with some acetone -- but the time/cost make it a waste. You need to by extra tips for each use.
I have never tried to clean the tip I bought extras it would be very messy to try to clean. The tip is what mixes the two components. I would suggest using a new tip
Short answer: No. Longer answer: It might be theoretically possible to use compressed air or solvent to force the residual epoxy out of the tip, then flush it with solvent. But it would be a huge hassle. Basically you need a new mixing tip every time you use a cartridge.
No , which is why you get 2 when you buy it. If you were stranded on Gilligan's Island and had no other option it may be possible by submerging it and purging it with Acetone . I wouldn't try that unless Gilligan was driving you nuts
Not to my knowledge. The tips purpose is to mix the 2 parts of Thixo epoxy so that they can begin to cure, consequently the mix hardens in the tip. I'm not aware of any method that would efficiently dissolve the mix before it begins to harden.
No. They are disposable.
Can this be used as a fillet for stitch and glue boats ?
Don't know much about stitch & glue, but as long as the materials are wood, and to the extent that the joints do not flex much, I would bet that Thixo would work well as a fillet. My application of the product involved zero flexing and it works extremely well. I don't know how it reacts if flexing or twisting were a regular requirement of the cured application.
Prefect for that task
Yes. Absolutely. Run the bead and then flatten it with your filleting stick.
Thixo2:1 would certainly work well.It is however an expensive way to go if large quantities are needed. I use my own well measured and mixed small batches of standard epoxy mix thickened with wood flour and fumed silica (Cab-o-sil) to the desired consistency and spread and fileted with a spatula. I will choose my epoxy hardner (fast or medium) based on how much working time I need. For a small job Thixo would be great.
Small aera fill
Great for filling small areas, unfortunately the mixing nozzle is not cleanable, so need new one for further work. So far I have not tried using it after the first round, but the two parts of the mix are still soft.

I would buy this product again
I used this to glue plywood sides and bottom to frames and other structural members for a skiff I am building. The glue worked perfectly with hand clamps. It did not run on vertical surfaces. The mixing tips worked great also. It does take some strength to gun a couple of tubes, but you have quite a long working time so there's no need to rush. It makes for much less mess than sometimes results from mixing large batches of thickened epoxy.
hard to pump out, applicator tip clogs
like others have stated, the applicator mixing tip clogs easily. maybe it just needs really warm temperature but I wish it would come out! eventually, you cut it open and mix it manually which you can simply do with regular epoxy and thickner.
I really liked this product. I filled over 80 interior screw holes in under an hour in a 1976 13 ft. Boston Whaler Sport I found to restore for the grandkids. Some of you may say this was slow but bear in mind I'm 74 years old and not as quick as I used to be. Also, I used a standard caulking gun and after a while I found myself using two hands to squeeze the stuff out so get a better one. But I got 'er done. Zap, and the screw hole is filled. Zip, along a gouge and it's filled. After all was filled I took a Popsicle stick and gently pressed on the filling. This was what the Boatworks guy recommended in his video but I found afterwards it seemed unnecessary. We will see when sanded.
Right product for the right job
Thixo Epoxy system cartridges are easy to use and with the mixing applicators, any amount, from a very narrow bead to bulk applications can be applied to the work site. It makes incredibly strong bonds with wood and fiberglass. For doing small jobs, over time, where there is half a tube or more left after using both supplied mixing applicators, having a third available would be nice. Otherwise, you'll need to order a pack separately. Great product though and just ordered two more to keep on hand.
Easy to use.
Backyard Whaler restoration
Just used my first tube of Thixo this past weekend. About 1/3 of the port gunwale repaired. Only have time on the weekends to devote to the boat restoration. Thixo is saving a lot of time. Very happy with the results.
Good just not what I needed
I was glueing some brackets one at a time and tried to just shoot a couple of squeezes without the mixing nozzle in a cup and stir it- that worked fine but plugging the tube back up not so much- I glued the little plug into the tube and had trouble getting it out- for me using the nozzle and using a whole tube in 1 shot would be great,
I use regularly
I use to fix rotten deck core, glassing overhead when fighting gravity, attaching anchor chain locker bulkhead and fixing old through deck holes prior to re-drilling bolts. all on my old Pearson 35. Keep some around and use in conjunction with penetrating two part epoxy. also see the Thixo wood.
Definitely a keeper!
We used the product to repair fiberglass aircraft tank molds. High stress areas were repeatedly cracking. We tried the flexible epoxy repair and it has worked.
