How do you level a floor?

[#1]

A dedicated floor laser makes levelling any floor a super simple process. The Lasertec Floor Laser projects an accurate 360° horizontal laser line guide, and unlike standard lasers, the beam is projected only 8mm from the floor's surface. Combined with Lanko 20kg 173 Floor Leveller, perfectly level floors are a task anyone can achieve in their own home. - MitchellMc

One option is to use a self-levelling compound. Example video below… - MartyH

We need to level our laundry floor.  & then waterproof so we can then tile and do the rest.

However I cannot find anything specific enough to enlighten me as to how long you need to wait between self-levelling the floor and waterproofing.

Can anyone assist? We have the Dunlop level ready to use & the Crommelin waterproofing stuff ready also.  Primers for both and all the gear.  Just not wanting to jeopardise anything and also not wanting to have no laundry (4 kids) for longer than we need!

Welcome to the Bunnings Workshop community @jen321. It's terrific to have you join us, and many thanks for your question about floor levellers.

Would you be able to link me to the exact product or take a picture of it? That way, I'll be able to confirm curing times. There are a couple of them, so I want to be sure I'm providing the correct advice.

Please let me know if you have any questions.

Hi @jen321 

So, we're going to use the Dunlop 4L Multipurpose Primer over your concrete (I presume it's concrete; let me know otherwise) and wait a couple of hours for it to dry. Next, apply the Dunlop 5kg Floor Leveller and give it a good 24 hours to cure. You'll then be able to apply the primer again, wait two hours, and apply your membrane.

Please let me know if you have further questions.

Thanks so much & even better that’s the answer I was hoping for haha

Can floor levellers be used section by section?  Something like I do a small section one weekend at a time (using one 20kg bag), for maybe 8 weeks?  What can go wrong? 

I have an old garage that we use as storage (boxes of stuff, old bikes, etc, but no vehicles).  The floor is bare concrete. Some parts are uneven. Some sections have loose concrete or rough (the aggregate is showing).  I'm thinking of trying to use a floor levelling compound to smooth and level the floor, and later put on floating floor boards to turn it into both a storage and rec room.   But because it's a large garage (9m x 6m), I don't think I can do the levelling in one go. (The other reason I'm thinking about this approach is I don't have any other place to put the stuff that's in the garage. It's only half-full so I can move all the stuff to one side, level the empty side, and then move the stuff to the levelled side and then level the other side. 

Thanks

"Something like I do a small section one weekend at a time (using one 20kg bag)" 

To clarify, I mean use up one 20kg bag at a time, covering only how much it can cover, then another 20kg next week, and so on.

Hi 

I’m laying a floating floor, including over the tiles in the attached photo. Do I need to use floor leveller on the tiles or will the foam underlay be ok? Also the floor laser doesn’t seem to be available any more - what is a good alternative?

thanks!

Hi @palo,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

As a general rule, all voids and variations should be filled with a self-levelling compound before a floating floor is put over them, but I'd suggest you check the allowable tolerances of your specific floating floor product to see what the manufacturer recommends. They may be happy with very small variances. 

You can really use any cross line laser level, the laser will just not be as close to the ground. If you set your laser up so that the line is, for example, 100mm above the ground, you can cut a block to 100mm or simply just measure down from the line with your tape measure to check that everything is level.

Let me know if you have any further questions.
