I don’t care if I have some soft spots.

This is a terrible product. It's extremely dry and sandy. Forget about getting smooth level surfaces. It also dries almost instantly once applied. Also, you will need a lot more than the package says.

Just like the Henry flood patch material, the directions on the container are so small they are unreadable. Quality control on direction to use and install the product are very important.

So I bought this product and had to KZbin the manufacturer directions because the directions on the container were so small!!! How about some quality control on your packaging. Geeze. I need a magnifying glass

I love how it says, “do not use a broom” to spread primer in the directions… but still use a broom to spread the primer

What's the difference between henrys 647 and henrys 650?

I bought a tub of the premixed. It isn't white like the video, it's kind of orangey-beige, and it's *very* gritty. Like wet sand that hardens. Not at all what I expected from this video. The container says Henry 345 Floor Patch (bought at big box home improvement place), so maybe it's a different product with the same number on it?? At any rate...too gritty, and I don't recommend it.

Yeah MK Henrys Is Still operating like a 90 yr old company founder is still running it out of a small town USA. Probably using hand written paper order entries to communicate with their warehouse people and others.

What do you recommend for crack repair up to 2” deep? Could this be used for that?

Can I paint only over this product?

Wht good for vinyl sheet on concrete floors???

Is there a self leveling patch for sheet vinyl over concrete? Thought I was going to remove this sheet vinyl, but the installer apparently used $5000 in glue and $50 sheet vinyl. Small residential area, no room for equipment.

I have an old vinyl floor i thought i was going to remove. There are nails everywhere and old black mastic underneath. I removed a small area to see if i could remove. It is very difficult. So i am wondering if i can use the 547 to trough over the old vinyl and little bit of exposed mastic or tar paper? Would i need the 546 additive? You dont mention for some reason??

Thank you for these basics. Would’ve been nice to see you repair that original messed up floor. But the implication of your video is that I can use it to fill in that big wall gap in the floor.

we put down vinyl tile, we now have green glue coming up thru the cracks, is there a Henry product that is moisture resistant.....the slab may be sweating, dg

What is the difference between 565, 555 and 544? I have about 285SF basement concrete to go over and dont understand the difference?

Can I paint on an epoxy floor after it dries… basically is it “paintable”???

Can the floor be moved slightly after it has laid

From what I’m seeing Henry don’t want to helps us .

Hi . I had two guys lay my flooring today using Henry 650R . They did small rows like 4 at a time . Put the adhesive done and then the strips of flooring. Well the second guy used a wet rag o get any over runs up . But now that all the flooring is done when I walk on it , it’s like u spilled sweet tea on the floor and it dried and now it’s sticking sounding when u walk on it . How do they get it off the flooring . And he must not have none you were to wait tell it dried before he laid the strips of vinyl flooring .

self-leveling underlayment can you do second coat?

This stuff is awful

Omg I have a small bottle of the primer. It’s pink color. My mom thought it’s some sort of floor cleaning liquid. She pour some into the water then noticed the pink color looked weird as floor cleaner. So she dumped the water into the toilet. Now I am worried the water may still be kind of sticky and make the drain pipe build up stuff.

I just used this today to level a bathroom floor for sheet vinyl. The product is extremely gritty, like it contains silica sand. Don't expect a smooth feather edge and it's only workable for a few minutes before it starts drying and sticking to the trowel. My first application was a pain because I tried to touch up some spots and had divots In the surface that were hard to smooth out. The second application went better because I didn't try to touch up areas after the first few minutes. It works fine for underlayment if slight imperfections aren't going to effect the final result. Also it's hard to sand so don't expect to be able to work out divots. All you can do is work off sharp corners.

A minimum of an eighth of an inch over the highest point of the floor? This is $40 for a 40lb bag.....

Anybody use psa to carpet a ceiling?

What's the difference between 547 and 549?

Per directions in this video and on the package, I mixed a 25 pound bag with a 3:1 ratio of powder to water by volume - about 2 1/4 units of water to about 6 1/2 units of powder. I used a paint mixing container to measure my water and powder, about 1 1/2 quarts. Converting to quarts - I used about 3 3/8 quarts of water to 9 3/4 quarts of powder. I stirred with a drill for three minutes and the mixture hardened in my bucket within seconds. Instead of fixing a low spot on my subfloor, I ended up with a 5-gallon bucket filled with 25 pounds of solid cement ready for a landfill. I returned the empty powder bag, along with a bucket of useless hardened cement back to Home Depot and Home Depot exchanged it for another bag. This time, I used 4 containers X 1.5 quarts each = 6 quarts of water with a 25 pound bag. The mixture was about the consistency of pancake batter and lasted 15-20 minutes before hardening, as expected. But it did not fully dry for more than 24 hours after spreading it. You need to update your mixing instructions on both the packaging and this video. You should also reimburse Home Depot for taking back my empty powder bag.

can this be used to level osb? dip is about 4 feet wide and a 1/4" deep

Can peel and stick go over it? Or adhere to it after it drys.

Can I use this to level a bathroom floor that slopes 1/2" end to end?

Henry, you should have a tool on your website to determine which product is the right choice for the consumer. Simple to create, they would choose by factors such as material type, substrate, wet/dry set, permanent/pressure release, indoor/outdoor use, floor/wall installation, etc. Thanks!

Will 647 adhere to well bonded sheet vinyl as a substrate?

Will 647 adhere to well bonded sheet vinyl as a substrate?

So what happens wher it sucks moisture out of the old concrete and buckles uo

The instructions I was given on the mixing ratio was 2-1/2" cups powder to 1 part water. First time I'm hearing 3 cups. It would be way too thick with 3. I will say that this needs the 546 additive. I used water instead and it cracked, but the layer I did with additive was extremely solid.

That looks a lot smoother than it did for me when filling gaps and nail holes in plywood subfloor. It went on like wet sand and dried very rough. All the instructions and videos I found said this was good for plywood subfloor under self stick vinyl but now that it's dry i don't think it will stick very well. Can I sand it and prime over it? I was expecting something more like wood filler (which maybe I should have used.)

I want one of those tshirts! Lol. About to lay my lvt with Henry 647!

it applies easily, but no way was 45 min enough drying time. It took 4 to 5 hours to dry to tacky. was applying large format industrial thickness vinyl tiles to a plywood substrate. the Mudroom floor is gorgeous now but what I expected to be a 2 day job max took more than twice that due to the longer drying/wait times for each section.

I take it it's not for VCT...?

Best thing ever. Whoever invented this is a genius.

Install up to 5" thick what it says, so that's not all in one pour I assume?

This takes FOREVER to dry. I follow instructions and put on a 1/4" layer. It's been 5 hours and it's still completely mushy. I checked reviews online and lots of people have the same issues, they are reporting it takes more like 6-8 hours between coats. If it's not dry by tomorrow I'll scoop it all back into the tub and return it. Maybe should have gone for a mix, I don't want to wait all week.

Looking to lay down some carpet on my garage floor. Is this applicable to using carpet as well? Thanks!

No additional adhesive is required when doing a repair?? Is it ok to add new adhesive over cured adhesive, or will that cause the original layer to dissolve and pull up?

Where can this be purchased at in Northern Ohio?

Thank you for the guideline of 45 to 60 minutes for drying. Thanks for explaining that you have to avoid cleaning for five days after installation as I would never have thought of this. Some of the other videos don't explain this very well. I have never installed vinyl before and so really have to start out with basic rules.

Can you prime and paint this?
