can you have a section of your basement floor skimmed to make it level?

Question

if so what kind of cost would I be looking at for 400 square foot?

when they waterproofed it screwed up the levelness of the floor

Answer 1

How far off is the level? if it,s less than 1/4 inch thats standard, check at a flooring store they might have a prouduct , i,v heard if one called pour and level, it wil seek out the low areas,

Answer 2

You have a bit of a challenge here. the contractor has applied a sealant to the concrete floor! Man..this is labor intensive, at first!
The floor area you want leveled off has to be scaraffed or scraped so the new flooring compound will stick. It may be possible to use an abrasive pad to scratch the surface and give you something to adhere to .

Ether way, the sealed floor needs to be prepared proerly for the levelling compund, or it will just chip off.

Without being accusatory, call the contractor, and ask him if there is a sloution he recommends that may remove the sealer in the area in question. Tell him you are thinking of treating that floor with a different finish. It isn't telling a fib, just not divulging what you want to do to fix his faux pas!

Once the floor is cleaned of the sealant, you must add a concrete bonding agent to the bare concrete. Now the fun really begins!! there is a concrete mix called self leveling concrete. it is quite fluid, as you can imagine. The biggest challenge will be to make sure the floor is as clean as you can get it!!

First, lay down the bonding agent, as quickly as possible. Read the directions very carefully. If you go to Home Depot, they have a few different types of bonding agent. Ask the Pro Desk for the right one for your application.

Next, apply the self leveling concrete, trying to spread as evenly as you can, as you apply it. The concrete will settle into the low areas, adn run off the high areas. You have to be aware that as you add concrete, there will be a slight difference in the elevation of the floor, in some spots. Be careful not to create a trip hazzard!!

This is a time consuming and laborious project, now that the floor has been sealed!!

You may want to consider hiring a professional that has the right equipment and knowledge to do this properly.

yes, but don't forget you'll still need your head height. so be careful of how much screed is laid. all you need to do to make sure the new screed adheres to the old surface is give the existing floor a couple of coats of uni-bond.
for the price, just call in a builder for a free estimate.

Answer 4

it depends on what finsh you want.if you just want to skim it with portland cement then id say 3 bucks / SF or 1200 dollars

Answer 5

if it's painted you'll need to strip it. the surfacing compounds won;t stick to it. otherwise it'll need to be chemically or mechanically etched to give it "bite"
