Thanks very much for the info it's much appreciated I'll use a straight edge to level it off but should I float the surface as it starts to stiffen of just leave it.would floating give a harder final surface plus is 4.1 the best ratio for this

Yes I have some

Thanks for the reply. Ok so the stove is a cassette type. Most of these heat the hearth to 100 degrees or above. (As opposed to stoves in legs which don't heat to above 100) So this is what is worrying me having said that the bond layer would be approx 50mm below the surface as the screed will...

Ok so my head is full of dilemmas. So I used sbs bond to reface some crumbling concrete window sills and applied a thin skip of screed (about 3mm) before painting. This has held for years so I know it's a good product my issue is that because the hearth will go right back and the stove will sit...

I've attached a pic of what it's currently like. You can see I need about 30mm. So would a dryer screed be best or a mix more similar to mortar

Is there anything I can do to remedy this. I'm at my wits end with it all. I'm a diyer so just need advice. Surely when people chop out old hearths they sometimes have to patch them up or raise the level

Ok I see so really I need to chop it all out and start again. Just a thought but could I try and add a mix similar to render. No idea what mix is used for this but aren't thicknesses similar.

I was thinking exactly the same regarding footings. Floor is suspended timber and I want the screed to finish at floor level. The current level of concrete is about 30mm below floor so I need to raise it by that

Just general search on net saying it needed 1 day per mm before I could screed over it

Sorry meant reading not hearing

I need to raise the level of freshly laid concrete. By about 30mm I Planned on laying 4.1 screed over it but I'm hearing that it needs to fully dry out before I can add the screed. If it is possible would I need to apply a cement slurry first

I'm just about to start bricking up to create new enclosure for inset stove pic shows roughly where bricks will be and trowel is were stove will eventually be positioned. The base is concrete but needs raising up by about 30mm which I planned to screed with grit sand and cement. Question is...

Ok so pressume this is because tamping brings more cement up. Soi plan to tile this so will I need to chop out the top layer and re screed with tamping and trowelling

I thought that sharp sand screed would result in a harder surface than soft sand is this not the case

Ok so I laid it all at the same time with the screed going straight onto the concrete. So would you expect to be able to rub sand off it. Also if a wet it and rub I get a sandy/cement slurry as though it's not fully set but expected it to not do this after seven days.

I have recently cast some concrete and finished the top off with about 30mm of sharp sand screed. The concrete was mixed 4.2.1 and the sand screed was 4.1. the issue is that I'm not sure that is hardening correctly. Its been laid for a week now and gives of sand when rubbed.hard I've added a...

Does anyone have any experience with flue liners. I'm building up my fireplace too accept a inset stove which will have a 125mm liner. My issue is that the front of the flue spigot will be almost plum with the back of the lintel.the lintel sits approx 200mm above the sigot but I also need to get...

Finally got round to gettin the concrete in.floor is a little uneven and wanted to get the hearh nice and level so built a little frame to give myself a guide to work to

Yes I had actually also considered that option too with quarry tiles . Also wondered if I could just screed the area with some heat resistant cement type product. I think my main concern with all the options (probably way overthinking it all ) is how whatever I use will stand up to the heat

Thanks again for the reply so basically (if I've read it correctly) your suggestion is to make a stepped hearth which is approx 18mm higher in the recess.tiles would then lay flush upto the higher level in the recess
