screed

We had an extension built a few years ago - this resulted in the concrete floor of the extension abutting the existing wooden suspended floor in two rooms. The kitchen floor works perfectly - but the back room was/is a problem. I recall the activity at the time when they built the back room...

Good afternoon everybody, I have recently purchased a house with old asbestos floor tiles. I am having these removed after being convinced by others to screed over - luckily only one bedroom and hallway was completed. The screeding/latex has laminated (like puff pastry) and is breaking up. I...

Hi all, I ordered 4t of readymixed floor screed from a company yesterday in order to raise my garage floor by circa 75mm. The mix looked quite dry but the driver managed to make a ball and said it was ok. I laid the screed but I couldn't float it flat as it seemed too dry. I compacted and made...

Hi All We are renovating a 1980s built house and intend to fit UFH throughout. In the existing part of the house the floor is made up of 4" of hardcore, DPM layer, 4" concrete with 2" screed over the top. Given that there is no insulation in the existing floor will overlay UFH in EPS panels...

Hi all, I’m currently self-building an extension to my property. I’m adding an 8m x 6m single storey extension with steel work to possibly take a second storey in the future (when I win the lotto!) I’m wondering can I put the concrete floor slab, insulation and screed in once the roof is on...

Hi all, I am preparing to screed my concrete subfloor, having pulled out the old one which was uneven and full of redundant pipework. I am the top-floor flat and there is a riser for the soil pipe, mains water feed etc running inside the flats. There is a gap between the structural concrete...

Hi everyone Looking to screed a 5m x 5m floor, which will be tiled on. Are there any additives which we can add whilst we're knocking up to speed up the drying time please? If anyone has experience, please reply!!! I've read that ronascreed 8 is an additive that allows you to rule 8 days after...

hi, I've got a 1950's house, it had a few small rooms on the ground floor with parquet (fairly low quality wood, badly fitted). Previous owner removed some of the walls to make the place more open plan, all good. The problem is that the rooms floors were laid individually so there are a few...

Hi all - I'm a new member here, so hello from me and thanks in advance for any help that you may be able to offer. I live in a 1950's built ex-council house which has cavity walls and solid floors throughout the ground floor. These are or were all covered in a red composite which I believe to...

I understand I should allow around 1 day per mm of screed before I go ahead and lay a final floor finish. I wondered though if it's worth gradually turning up the underfloor heating to 'force dry' the screed and speed up the drying time? Is this a known practice? If so, does it make much...

Hello all, Just started renovating my new property and I have a couple of questions about the floor: - as per the photo attached, it seems like it has a concrete base (it seems like concrete blocks or something, judging by the dividing line in the photo?) and then some sort of screed mix on...

Advice please! I have a 5m x 4m extension underway. Got my slab down, with the insulation boards under whacked down type 1 below the slab. My plans say to put 75mm screed down, BUT no allowance has been made for dry underfloor heating - and the bifold company are due to visit for measurements...

Hi, I have a fairly even concrete floor (about 120 sq meter) but has some damage to it at places where the top chippings have come off in a couple of places (about 20mm deep), but in total this damaged area is just about 2 sq meter in the whole floor. anyhow I am planing on ordering slc but...

Hi, I have a toilet with drain in the floor. I want to screed the floor, raising it about 100mm, and add a new toilet, sink and washing machine trap. My first thought was to get an extender that will be buried in the screed. This would then join a 90 degree pan connector with boss, to connect...

Hi. Renovating a single room extension (c1980s I believe) attached to a c1800 stone house. I intend to install a laminate floor, and because of some undulations need to level the existing base. When lifting carpet grippers (tacked down but also glued in places) parts of the floor lifted with...

Hey guys, I'm going to be installing underfloor heating with 10cm insulation, topped off with a 5cm screed. The area is just over 35sqm and will have a kitchen, so there will be electrics, water supply and a drain installed. For the drain to work, it obviously needs to be at a slope. The...

I am building an extension which is going to have a multi-media cinema and will require a large amount of network cabling. Do regulations on running cable through conduit under screed apply to low voltage network cable? I would ideally like to bury some flexible (non metallic) conduit under...

Hi - could I source your thoughts on concrete drying times suitable for flooring? We've replaced a ground froor slab (44m2) with a DPM, 6" concrete, 100mm kingspan, and 65mm Anhidrite Screed containing a wet loop underfloor heating system. The Screed pour went in 33 days ago, followed by...

I have removed some seriously ugly and thick floor tiles for my kitchen - area 4metres by 9 metres. This has left the adhesive behind in 'blobs' with multiple holes etc. I want to put down vinyl and need to level the floor, the current situation leaves me with level changes of 5mm plus and the...
