    Fireplace render??

    The fitter will need to be HETAS registered. I am going through the same project which I haven't yet started, I just need to finalise an issue on which sand to get. There are different ways to go about it, I have chosen to render the recess of my fireplace with hydraulic (or hydrated) lime...

    Thin coats of Hydraulic lime in chimney for a woodburner

    Thanks Stuart45 for your expert advice. Surprisingly I cannot find anyone who stocks hydrated lime in my area. I have found a supplier who can provide me with a couple of bags of NHL hydraulic lime. Doing it that way seems cheaper than I thought but now I seem to have the problem of finding the...

    Thin coats of Hydraulic lime in chimney for a woodburner

    Thanks Stuart45. Just wanted to double check and I'm glad to know that lime is relatively heat resistant and I that can apply it on two coats. I'm looking forward to my small project. Just two final questions, could I buy hydrated lime from my own local builder's merchant or is it best to get it...

    Thin coats of Hydraulic lime in chimney for a woodburner

    Thanks for those links Richard and Stuart 45 for the brief info about lime. Last time I looked at the Vitcas website for heat resistant plaster the price was a reduced 50 quid just for 20 kg (excluding delivery)! I've also heard that lime is relatively heat resistant (I hope) and I'm curious...

    floor slab with damp proof membrane on surface?

    So in my case shall I remove it and replace with something else to level the floor? i'm trying to understand why you can apply a screed of between 1mm and 6mm using self levelling compound but not a sreed of the same thicknees using premixed sand/cement mortar (very fine sand)? Unfortunately the...

    floor slab with damp proof membrane on surface?

    Mountainwalker, as you metioned if I were to put a weight of 10 Kg on a sheet of wet newspaper, it's logical that it will go straight through it. What's not so logical is that I haven't gone through my 4mm screed of mortar, it's still in perfect condition. If you think someone is not doing the...

    floor slab with damp proof membrane on surface?

    I have used self levelling compound twice and it has cracked under the heat of the sun, that's why I decided to buy a bag of mixed cement of sand mortar and apply it to fill the gaps where the vinyl tiles were taken off because they were broken. I haven't put my laminate flooring yet but the...

    Thin coats of Hydraulic lime in chimney for a woodburner

    Thanks for your replies. Isn't hydrated lime more difficult to work with than hydraulic lime and takes longer to set (the advantage being a lot cheaper)? Could I apply two coats instead of three to make a total thickness of 10mm? The gap of 25mm between the woodburner and the sides of the...

    Thin coats of Hydraulic lime in chimney for a woodburner

    The hydraulic lime I would like to get is premixed with sand and lime and does not contain cement. I just need to add water. I haven't bought any yet. What i'm trying to understand is why the supplier told me I need three coats but could not give an explanation as to why it needs to be thick. So...

    floor slab with damp proof membrane on surface?

    Fill in the gaps where the tiles have been taken out. I would apply the same thickness as the vinyl foor tiles, mine are around 3 to 4 mm.

    floor slab with damp proof membrane on surface?

    I had a similar experience the other day. My tiles are of a dark brownish colour and seem to be hard vinyl (house built in late 40s). If they were also partially made of asbestos they would look fibrous I suppose. One area of the screed seemed hollow so I took some of the cracked old mortar off...

    Thin coats of Hydraulic lime in chimney for a woodburner

    My main problem is to find an adequate and reasoble material to cover the brickwork. I took the gypsum plaster off the fireplace recess and the face of the chimney breast because it's not heat resistant. I could apply sand and cement render but I think it would be more prone to cracking...

    Thin coats of Hydraulic lime in chimney for a woodburner

    Hi RedHerring2 and thanks for your reply. I have looked at the Building Regulation part J 2010 and section 2.28 reads "Combustible material placed on or beside a constructional hearth should not extend under a superimposed hearth by more than 25mm or to closer than 150mm measured horizontally...

    Thin coats of Hydraulic lime in chimney for a woodburner

    Before my planned project I have spoken to the Building inspector who told me there needs to be a 150mm gap away from combustible materials, if not combustible then to follow the manufacturer's instructions. When I rung the manufacturer they recommend 80mm to allow enough air to go around the...

    Thin coats of Hydraulic lime in chimney for a woodburner

    Hi, I want to cover the brickwork on my fireplace recess and also on the face of the fireplace prior to installing a woodburning stove that will give off convected heat from both sides and the rear, radiant heat from the front. I am involving Building control who will check the work done. The...
