hi, im about to embark on my first concrete floor job and could be doin with some info please.

the floor is a bit rough so have decided to use SLC to flatten out the irregularities before actually tiling it.

firstly does the actual conrete need anything doing to it other than a good clean before applying the SLC?

secondly, when the SLC is down, what preperation does this need before i can tile onto it. its just some bog standard ceramic tiles im using.

thanks for any help

Hi Rodger, brush the floor throughly and apply a good quality bonding agent to it, dont use PVA.
Once you have laid the SLC this will need to be bonded before tiling starts.
What SLC are you using?

i havent made a decision yet TBH as i have only just looked at the job and decided that is what needs doing. Never used it before so i dont have much, if any at all, clue about it.

can you suggest one thats suitable along with an apropriate bonding agent?

thanks for the help

Tile giant stock these items if you have one near to you.
They actually have latex plus which is a 2 part product.

You could also use a one part SLC thats available from most good retailers, use an acrylic bond such as primer g

yeah theres a Tile Giant in Hillington, near Glasgow iirc. i'll head up there and see what they've got to offer.

thanks for the info, much appreciated!!!

primer g is good by mapei. i tend to mix it with a bit more water than it states on bag you usually put 5 litres of water i would use a little bit more so it runs nice and free

primer g comes in a bottle and is a liquid

just 2 elaborate when mixing the slc i usually add extra water above the usual 5 litre standard amount i find it runs alot better . primer g comes in a blue bottle and is made by mapei .hope that clear things up

hi roger

how long has the concrete been down???
if its a while, then it will be very dry and very porous too!!
give it a quick scrape if there are any high spots and a good brush...sprinkle some water down too to grab the dust and put a bit of moisture into it (only if its not recently laid )
i would use sbr to prime and then hit it with your slc
mix it in a gorilla tub and pour ...dont hang about too much, pour spread out with a trowel or squeegee etc and when you have done a section use a spiked roller to take any air bubbles out.....then onto the next section till done

you can pick a cheap spiked roller up from ebay for around £19-00
make the mix so it runs easily, let it do the work if you get my point

Try and stick to the manufacturers mixing instructions, if anything ever goes wrong at least you can be sure you did everything right.
I mark my buckets with a line to show how much water is needed.

as ASTON ABOVE for me!!!
that was funny, we all get the wrong end of the stick sometimes, just chill guys!!

i once stuck to the manafactures mixing instructions when making some yorkshire puddings they were as flat as a fart .dont believe everything you read

Was that a bagged ready mix for puds??

I mix with 5 litre water, then help flow with feather edge.

cool i'll get a roller ordered or see if i can pick one up at Tile Giant when i'm up there.
the concrete has been down as long as the house has been built so about 60 years lol.
so use SBR to prime the floor, pour the SLC then prime that with PRIMER G then?

In a nutshell............yes.
