Concrete Subfloor Preparation for the Vinyl Floor Installation How-To DIY Mryoucandoityourself


Here is one of my last project where I am doing the concrete subfloor preparation for the vinyl floor installation. In one video I show you my work which I made for three days in a row. Professionalism is growing from year to year. I think this is my best subfloor leveling in my life.
Hope this video will help you to get more knowledge about concrete subfloor preparation (especially subfloor prep for vinyl floor installation). Do not hesitate ask me some questions. I am here to help you.
What's inside "Concrete Subfloor Preparation for the Vinyl Floor Installation":

00:17 Old concrete subfloor was painted and very soft (had lots of sand), so I had to delete it completely and start subfloor preparation from zero.
00:23 Here is old concrete subfloor deletion.
00:29 Filling in big gaps between subfloor and walls.
00:34 Filling in concrete subfloor cracks.
00:54 Applying L primer for concrete subfloor.
01:01 Applying S primer for subfloor with vinyl.
01:19 Concrete floor leveling compound preparation.
01:29 Putting concrete floor leveling compound.
01:37 One more time
01:46 And more.
01:56 Rolling out the concrete floor leveling compound with a spiked roller.
02:07 More concrete floor leveling compound...
02:19 Here is what you should get.
02:26 Next day...
02:29 Make your new concrete subfloor very smooth because the vinyl floor is very thin.
02:36 The concrete subfloor is ready for the vinyl floor installation.

You applied the vinyl floor directly on it?
smoky 213
what grid or wheel grinder did you use to smooth out the floor after you threw in the leveler?
yo bro good wht
I did the same but i got Sandy cement surface, what can i do in this cause to install plastic flooring tile with adhesive
misselissalk
Did you use the L primer on top of the concrete leveler as well? Also why is the primer necessary?
cory zirk
I appreciate trying to do it right, but that was (in my opinion) a huge waste of money levelling that floor.

Steps I would have taken.

Seal the concrete, and caulk cracks.

Find high spots, and grind them flat with grinder/flap disc depending on how bad it is.

Install floor.

Awesome thing about lvp/lvt is you just need a flat floor. It will contour to any imperfections in the floor (ie a high spot in a room, where's with tile, that tile would have 4 corners of lippage.

Vinyl is designed for, among other things, speed of install.

If I was doing a tile floor, I would have taken the steps you did, and perhaps a couple more

What tradesman does concrete subfloor preparation as I need someone to fix my concrete flooring before luxury vinyl installation.

Self leveling concrete is expensive. Don't do It this way. prep with underlayment concrete and skim called prep star. Use a trowel too
Tommy bee
Hi

Can u tell us what is the Name and Model of the self leveling product u use? Where did u buy it and how much it cost.? What siclicon Product for the concrete cracks to fill up did u use?

Do u always/still use self-leveling compound even if the floor had installed vinyl tiles before?

Thanks for you input
Sukhwinder Singh
That is serious overkill to add the cheapest flooring available on market.
Erin Bell
Our floor is level, would just putting a latex primer on it work?
Tommy bee
What kind of blade u use to smooth out the floor after self-leveling? I have diament cup blade, and is to strong remove the self-leveling all the way to the bottom. Thanks for u input.

I put my floors down without doing this and 10 years later every low spot I had has broke floor

Thanks so much for this video. It has been so helpful. I'm a ceramic floor installer by vocation. Now, I'm been invited to handle a 2,000 square metre hall with theatre gallery using vinly wood tiles. This is probably the first of its kind job in my country. We are a ceramic consuming nation, this project will go a long way in determining change of orientation, either to accept or reject adoption of vinyl tiles here. Please I need all the help I can get from you to successful execute this job. I'm willing to pay for my training. Once again, thanks for this wonderful video you made here.

Screed over vinyl? No! Even with any primer!! Scrape it up,the cracks should be feathered,much quicker and definitely seals them.use a trowel to skim over it,should only need a light rub next day if any
Sean Boxall
And not a trowel was used in this video 😂😂
Dylan Wooles
The idea is to skim the floor without having to grind it down after, try using a trowel then use a spike roller and never skim over old vinyl, vinyl is soft and can move which will crack the new skim.
nichole butler
What is the filler used or callex to fill the cracks in the concrete at 40 seconds?
Dean Evert
Do you have a video how to install the vinyl over the concrete?
My Opinion!
How is this a DIY, this looks like a ton of work for someone that has no experience. Looks like a recipe for a total mess, waste of money and time. Then you're going to have to call a pro to clean up the mess.

What is "L" Primer? What is "S" primer? I removed an old vinyl floor from concrete and am having a heck of a time removing the old glue. the old floor was installed 20 years ago. I've scrubbed and scrubbed and scrubbed. Do you think it's possible to use one of those primers on top of the old glue that remains? I am installing a new peel & Stick vinyl floor. If I could have left old vinyl on I would of but it came up while removing previous layer of peel and stick.
PS: My back, arms and hands are killing me!!

Your instruction is missing a lot of detail.

What type of disc and grit number to choose to grind or smoothen the sub-floor after self-levelling? Is the disc type like sand paper or those thick disc that used with Angle Grinder ?
pablo rooney
er, no. this is why you get a fkn professional in to prep it properly. crap mixing paddle for a start. mix, pour,trowel,spike, handstone buff then featherfinish.
Ryan B
As far as I know yalls work looks great, but is this much prep really necessary for a cheap vinyl plank for? If this was not a living room, could you have skipped some of these steps?
shawn Cheney
omg he s adding MEK and creating a plastic floor too? i give up. i just was trying to find an easy way to remove the glue. Wow!

Materials still gapped

I removed linoleum from a basement level cement floor and found that the underlayment of the vinyl was rather damp and smelled of mildew. Is there anything I should do in preparing the cement for the plank vinyl flooring. I am afraid the cement is drawing moisture from the ground and be trapped under the planks. Is there anything I can do to avoid this.
Billy johnson
I think this whole floor leveling process is a way to get more money out of you by the installers.. if the floor is clean, crack free and no moisture it's good to go.. I installed pergo in my house 15 years ago and the concrete was fine the floor is perfect to this day without doing all this prep... you don't need beautiful cement when it's going to be covered by pad and laminate...
Luis F Amador
Is look like is to much over work ..i know if you have the money and the time u want do the best .bout as a business .u get job where people dont want pay what the take to get job done right ..see all the time plus gas .help and material ..cost alot just to install vinil ..with all that i can put some better with almost the same amount of money and time
rita Rodriguez
What do you use to fill in the cracks in the floor and between floor and wall?
Daniel Pavlinak
from start to end, one word -
terrible
joe19812003
my floor is pretty level but I removed all the old tile and now there is a glue called cutback still visible, it's been drying out for 6 months now and is now longer sticky, is it ok to put ivc moduleo vinyl plank over it with out encapsulation of the cutback??
whatchinmewatchu
What a huge waste of time and money .. all that work and material just for a vinyl floor that will last maybe 6 to 10 years and be out of style in 5 years. Plus be a pain in the ass to remove. Watch out for contractors like this, they insist on "doing things right" but what they are really doing right is getting you to spend a bunch of money you don't need to spend. It should be a red flag when the floor only costs a couple dollars a square foot but you when it's all said and done you have 5 to 10 dollars per foot in the installation.

What a fucking waste.
