screeding help!

[dboden]

I am a newbie and on an ICA/NVQ evening tiling course in Nottingham.

Anyway I need to level part of my hallway at home, the area is about 2m square, starting at about 2mm running off to the front door to about 40mm.

I thought self leveling might become too expensive.
I thought sand/cement mix would be good practice. but is 2mm too shallow for this?

I then thought should I batten it about halfway, do the deeper part sand/cement, then wait for it to dry off then self level the shallow part.

Am I making hard work of it?

Ps. I,m in no rush, so don't mind waiting for full cement drying times.

Anyway any suggestions welcome.

Thanks in advance.

Hi

Dont make a habbit of all this leveling or you will never make any money

Unibond the base get some concret going and bring it up the best you can, your right concrete is no good at 2mm, you could level it but try to make the last bit up with some fast set. Save you some money and practice for you.

use bal-bond sbr with the screed instead of water, will give it extra strength as regards feathering it down to 2mm

I agree with sc24 on the screed but I would put a slurry coat on the floor first with neat sbr and cement as your screeding, scrub it in with an old bannister brush

only 2 sq metres! There are smoothing compounds ( 'self levellers') that will allow the incorporation of aggregate( fine chippings)size given in instructions. Use this mix to fill the main depth and leave a few mm for a final top coat without chippings. Screeding with SBR incorporated in a sand cement mix is fine also,and easier, but not to certain that it will feather down to 2mm

My head is bloody spinning now.

I,m doing it at the weekend and don't know which way to go now.

Sorry Len a little more than 2square mtrs.... its 2m x 1.8... if that makes a difference?

I think I might go the sbr route...... Whatever that stuff is?

cheers all anyway

:hang: sorry

use a wooden/plastic float to finish the screed , use it with a circular motion this will 'rub' the screed down to the existing floor to get the 2mm finish, when you mix the screed mix as a semi-dry i.e not to wet but crumbly
