What type of screed?

[Warrentdo]

Hello, I have a small extension ( 7mtrx3mtr) that just needs the floor finishing off. The insulation (150mm) is in.

Its south facing with sliding doors so will get some hammer from the sun in summer (approx 2 days :-)

There is no underfloor heating and the insulation to finished height is around 65mm.

I'm looking at gray white mixed epoxy as the top coat.

Question is what is the best screed for the job?

I wouldn't mind doing it myself if I can as I've done the majority of the build.

 

Regards,

 

Warren.

Hello, any advice before I put down a dry sand and cement mix?

Think you have chosen it, easy enough to do yourself.

Hello! 
 

Sorry, this fell through the net.

 

Are you DIY’ing or getting it supplied and laid by a contractor?

 

Dry S&C mix is fine, but at 60mm you’re close to the thinnest I’d do that at tbh. This sounds like a candidate for Cemfloor tbh, eg a liquid screed. 
 

If you’re going for resin atop then I’d avoid gypsum (Anhydrite) as there’s a laitence that needs to be removed (like a scum on the surface when cured) which nothing will stick to.

 

Do Clockwork cover your area?
