screed

Hi. I need to level a 24m2 room, but it's only me doing it. I have bought Mapei 3240, and I see that it says the open time is 20 mins. I assume this is time I have to work with it before it starts to set? Is there any way to lengthen this time to allow me to mix further batches? I dont need it...

We are having to cut out channels in our existing kitchen floor slab for a new kitchen island. I will need to place an electric feed for the sockets; cold feed, hot feed and a gas pipe. I will also have to re-do some drainage so will dig out for that and re-cover. So I guess I'm keen on...

Thank you for reading this message. There are a lot of posts already about floor screeds. But briefly, which screed please is right for a double garage floor that has an existing concrete floor with like a ripple surface effect, ripples up to about 3 mm height. Thank you.

Hi, please can someone help me here. I’ve had my garage converted to a kitchen. Floor was lower in the garage compared to the level of the existing house. Anyway, I am having an island with a downdraft extractor. I have UFH installed and the builder has forgotten to put in the ducting for the...

Hi I apologise if this has been posted many times before but I did try and search for the original advice but couldn’t find it We bought a new build property and the screed is cracking - the builders came, dug it out and relayed it and it crumbled a matter of days later again even in dry...

Single leaf breeze (not supporting). I dug a 100sq test hole in the ctr and found conc. below the screed so I figure using conc. blocks will be ok. Do internal walls require a dpc? I'm assuming it would be good practice to dig out a channel in the screed and block up off the concrete below...

I have removed my old finish floor board and came across some type of asphalt/cement mix slab 90mm thick. Black colour As this is a little bit uneven and would like to have a finish level all around the ground floor I have started to get someone to quote me for a screeding. I never thought...

HI I have a karndean floor (da vinci) which i thought would be down for life, but after 11 years 1 tile started curling up in a corner and was like that for a year or so.

Hi, I did have an account on here a few years back but can't login.. So I'm converting our basement into the babies future playroom but I'm stuck on floor choice. My current substrate is the original brick type floor which was possibly laid when the house was built c.1870. My main goal is to...

We are converting our garage into a living space, the floor construction is DPC, 2inch insulation and 10inch slab. We need to make up the floor level by 160mm. We are told we can just skim over with self-leveling as the floor isn't that bad, directly lay 120mm Kingspan, then lay directly ontop...

Hi, Just removed my old T&G plank and at the beginning I though that below I had a very strong Concrete flooring but this is not the case. I made few trial hole and the drill bits goes in like a soft cream and what come out is a black soil. the all flooring does not sound very strong and my...

Hi, I'm on the bit of renovation and found out after removing the carpet that my slab is in concrete with wood planks on top. I have removed some plank and some black paint seems to be on the slab. My question is because the living room has an extension and the level is 15mm different some...

Hi all, So I need to level 9sqm of a kitchen that also flows through to a 19sqm reception room. Now, the kitchen starts off concrete, then goes to those ancient vinyl type tiles on what looks like a bitumen base (I’ve scraped most of these off now), then an open archway into the reception which...

Hello, I have a new build property with detached garage and tarmac drive (slopes down and away from garage door). I am looking at improving the finish of the tarmac to the slab on the garage. In short, the detached garage has a concrete slab which finishes inline with the brickwork. However...

I'm having an extension done and my builders are saying that they will screed the floor after completing plasterboard and skim. They say "the last layer which will be the screed will be fitted after the plaster boarding and skimming as this is common practice". Is it really common practice...
