Waterproof top coat over calcium sulphate??

4 years U.K since they became popular i should say. been out a fair bit longer in Europe.

 

If you do that technique You first have to make the crack wider with a screed joint cutter so the DPM sand mix can run fully down the cracks

 

The cracks will repeat through any screed and the final floor covering

 

Nope, with a PU and sand it will run down very fine cracks, you work it in with trowel. If you plan on making cracks wider you need to use a product designed for wider cracks. You cant use PU dpm and sand on wider cracks.

 

You’d be pouring DPM on that floor forever to fill all those cracks May as well pump it in

 

Thats what the sand does, it blocks the gap up, but the moisture allows it to cure internally out, not the other way around and end up with a soft core. Dont worry, i know what im doing.

 

I’m not worried I’ve got RR201 and RR203 in my van

 

Yeah The Floors Awakens

 

RR201 is amazing gear

 

Yep, good products. Im just giving you a heads up easier and much cheaper way of fixing flow screed. What i mentioned will be launched as a system soon. Liek most things, they are around a long time before they get launched. Bit like that 49 you posted about. Its was developed 20 years ago lol.

 

Is it decorators chaulk rebranded ?
