Leveling concreate

stranger12

Hi all,

I know concreate won't stick to concreate so is there a way even uneven surfaces on existing concreate?

This is outdoor and garage base so not indoor

Also do you think concreate repair products really work?

If you Google for "self levelling compound" or "screed" you'll find any number of products designed specifically for this type of situation - all easily available online, at DIY sheds or builders merchants.

Many thanks fornyour help

Do you need a specific type of rake to spread it?

I have seen videos and it seems they use a rake

Depends on the area. But for a domestic garage I'd just use an ordinary trowel or float - a couple of quid from any DIY shed. It's basically a case of mixing the stuff, pouring it on, smooth it off with a trowel and leaving it to cure.

You can't use self leveller exterernally,nor is it designed as a finished substrate

some says internal and external

Some say it won't last 5 minutes as it's not designed to take load on it s on. SLC is very soft and will easily be damaged

You also don't apply with a rake, float or spiked roller

Exterior Levelling Compounds work well if you know how to apply them ? Ardex k301 is pretty good, cheap, idiot proof but plenty out there....

Concrete does stick to concrete

If i use the self leveling compound that covers between 3-40mm , how many times can you apply it over existing compound?

Is it something you can build it on top of the other?
