Please tell me what it is if you find it out. 😍

That’s what I was thinking. Like it’s a secret or something.

Since it looks like no one replied to your question, I'll provide my input. I have laid pallet wood flooring before, so I would say a flooring adhesive will work. However keep in mind that some adhesive expand a bit when dried. As seen in the video they sanded the floor to make it flush. But definitely a flooring adhesive will work great. To fill the gaps n the wood any flooring grout will work. Keep in mind I would treat the wood so the grout can be wiped off clean from the wood. Maybe some coats of polyurethane will help. Again you can always use a floor sander after adding the grout. Now for the finishing the floor you can use a polyurethane or epoxy on the floor. Keep in mind the epoxy will take longer to dry and more is involve with mixing it etc. Also make sure the the polyurethane or epoxy used is suited for high traffic areas to lessen the chance of cracks or other damages from furniture.

@@poseyserena02 Thank you very much for your input. Definitely expands my knowledge and makes sense! When I run across a flooring project I may tackle this idea. Thank you again!!

I would think epoxy was used. Seemed by the time they used it the wood acclimated and shrunk enough to eliminate most of its moisture content. It also looked like they added a little color to it to identify low spots during sanding. Beautiful floor

Their names were written on the plywood sub-floor...not visible but still there.

Two part epoxy clear finish (not sure what brand)

7/8" to sand down to 3/4"

Then gotta stack an fillet to let it dry an shrink

I think just the nothing but epoxy. Black tint could be just a pigment mixed with epoxy. any color

What type of laqacka have she used for the floor

Looks like either PL or liquid nails construction adhesive. She was squirting it on a piece of wood from a caulking gun and applying it to the individual pieces.

waterproof construction adhesive, took screws out after cure.

Same epoxy (tinted) poured into the cracks and voids. Many brands, some can be poured thicker than others. Careful of heat build up.

What brand of epoxy did you buy to cover the disc and where did you get it.

Don't remember brand, found online
