mapei fiberplan can be used on ufh. its water based as well

Am i right in thinking that with SLC you pour onto the floor and it will find it's own level or is their some spreading involved?

Never used the stuff before surprisingly

it doesnt find its own level unless you stop up any where it can run away this normally means damming areas with sand and mixing up enough self leveller to rise above the high spots it is a very expensive way of levelling floors only works really well if there are hollows in the floors as opposed to bumps which must be ground out to achieve a really good finish imo

Stopgap 300 waterbased is about as good as you will get for a self smoothing screed in my opinion,at about £18 to £20 a bag. A 25kg bag will do approx 4 - 5 m2. I prime the sub floor with a suitable primer (stopgap 121), let the primer fully dry, mix the powder with 5.5 to 5.75 litres of cold water pour the mix onto the subfloor direct the compound with a trowel and roll it with a spiked roller if you wish.
It will normally be dry enough to walk on in 4 - 6 hours and is usually ready to lay on the following day (providing conditions are good).
I have been using this for some time for fitting karndean, Amtico and various hard floorcoverings and have used it on quite a few tiled floors now with good results.

Cheers Chris.

if a poor floor has to be leveled either with boards or self leveling, thus raising the finish level of the tiled floor, how can a 'trip' be avoided when entering the room?:dizzy2:

does the spiked roller give you a good finish, as when i trowel it out, i never seem to get a really smooth finish.

 

[cjp1]

The spiked roller should give a perfectly smooth finish to water based smoothing compounds when applied to a sub floor that has been primed,
providing you have mixed the powder with the correct amount of water and you have applied enough to the floor.
After you spread the compound with a trowel or a gauging rake use the spiked roller to remove trowel marks and even out the finish.
Cheers Chris.

Biggest thing to remember with levelling compounds, make sure they are mixed well and use a SPIKE ROLLER!

hi guys and gals be sure leveling is done prior to w/p in wet areas because most dont like water and do crazy stuff if wet unless you can find a leveling comp suitable for outdoors normally twice the price:smilewinkgrin:

k think i made a big boob , first time using leveling compound,
followed the instructions on the bag mixed to a creamy paste and throweled it on.

now see i was thinkin throweling it on was ment the same as how you trowel on addy .

so i know ive most lively had it too dry, especially as it really made no attempt to self level.

im not worried about the level as i just wanted to bring the floor up a bit to save on addy.

but my real concern is will it stick to the floor and stay stuck, if it has been put on a bit to dry.

i did dampen the floor as i was going , but i did notice some little hair line cracks when i was leaving as if drying out too fast , any advise much appreciated

mmmm...how thick did you put it...and how thick does it say to go on the bag...?

 

[cjp1]

When I use stopgap 300 I mix it with 5.75 litres of water exactly, I always prime the subfloor with either stopgap 121 or uzin primer.
You can put on between 3 and 20mm stopgap 300 at a time using either a good trowel or a gauging rake then finish with a spiked roller if you wish.
I nearly always put the screed on with a big floating trowel and dont bother with the spiked roller and always get a good finish.I fit a lot of karndean and amtico so the finish screed needs to be near perfect to get a good end result.

Cheers Chris

 

[masonchat]

not very thick 3mm there abouts

 

[masonchat]

and bags says 1-3 mm

 

[DHTiling]

3mm is within what you can cope with by using a deep bed trowel...

If it has cracked then it needs to come up....
