Screed advice

**simhopper** · 05-05-2009

I have a customer who wants her existing tiled floor to be fiited with amtico

The area to be covered is around 25sqm and is to be used as a cafe

The existing tiles are well fixed onto a 12mm plywood base and are ceramic

What would you guys use, was thinking mapei fibreplan

Have never used a self leveller before so what should i watch out for

I have a spiked roller aswell if this would assist

Does it all have to be laid in one go?

Thanks in advance

You will find this info useful...

On ceramic or natural stone surfaces first
apply a coat of Mapeprim SP after the
surface has been cleaned with detergents
and mechanically abraded. Level before
Mapeprim SP has completely dried
(indents must still be possible to make).
Preparing the mix
While stirring mechanically, pour a 25 kg
bag of Fiberplan into a bucket containing
6.3-6.8 litres of clean water and mix with a
low speed electric mixer until a
homogenous, lump free, self levelling paste
is obtained.
Allow to slack for 2-3 minutes, then briefly
remix the paste after which it is ready for
use.
The quantity of Fiberplan to be mixed at
any time should be the amount required for
use within 20-30 minutes (at a temperature
of +23°C).
Spreading the mix
Spread the Fiberplan in a single coat of
3 to 10 mm with a large metal trowel or
with a rubber spreader, leaving the trowel
slightly inclined to obtain the desired
thickness.
Due to its extraordinary self-levelling
characteristics, Fiberplan immediately
loses the imperfections (trowel marks,
etc.
