Hi all, Has anyone used one of those grout waterproofers to help prevent grout absorbing water from the shower? I am paranoid about leaks and mould so trying to do what I can to minimise water getting behind those tiles. https://www.ltp-online.co.uk/prod/ltp-wall-and-floor-grout-protector Thanks

Thanks for the math. Does the levelling price seem fair for 60 sq m? I was surprised to see they wanted extra to prep before the self leveller.

Hi all, I've received a quote from a flooring company to install approx 60 sqm of Karndean flooring. They want £22.50 (no VAT) to fit the flooring. Doesn't include supply. On top of that they want: £148.75 - Rub down existing self leveller and prime (labour only) £392.70 - 4-5mm self leveller...

yes I’m considering taking it back to brick, but I’m not sure what would be best to level it. I’m thinking a rough bind coat and then 6mm backerboard screwed into the wall to get a finished level and plumb wall. I will have to re-waterproof it too.....

Yes, this is the product. https://www.builderdepot.co.uk/ardex-wpc-waterproof-protection-system-10kg I am not sure I quite get your suggestion in regards to the batten. I could install a backerboard to the wall to level it, but the shower tray has been installed and I’m not sure if be able to...

Wall in question:

Hi all, my shower walls got plastered and I have installed an Ardex waterproofing system to the shower ready for tiling. I’ve gone to start the job and noticed the bottom of one of the long wall is about 25mm out from the ceiling. There is also a bit of a belly in the middle of the wall. (Old...

Thanks for your input. Do you have the same size?

Hi all, Master bedroom calculations suggest a requirement of 5100 BTU. 4.7m x 3.6m Solid brick walls 3 external walls 2 sash windows I was planning to get two of these rads: https://www.directheatingsupplies.co.uk/stelrad-concord-lo-line-144-x-1200-double-radiator-148310 They are 2717 BTU...

Before I added the additional ducts, there was lots of water on the underside of the insulation and the timbers were damp. Since adding the ducts, we have had downpours of rain and all the timbers and insulation is now dry. However by adding the ducts we have now caused a possible issue with...

A builder neighbour advised I should just insulate the duct from the floor boards up and seal all gaps in the floor with expanding foam and it should be fine. The insulated duct will prevent warm humid air inside from touching the cold duct and prevent condensation. What I am concerned about...

Drawing attached. Let me know if you have any questions about it. No chimney in the kitchen.

The insulation (now removed temporarily) where is circled red was soaking wet. Also the underside of the duct all the way around is soaked.

The ground outside is about 12” from the top of that duct. There are existing air bricks on this wall but airflow wasn’t great so I core drilled 4” hole and added a duct which runs through the wall and down between the wall and joist. The opposite side of this wall in the house is an extension...

Hi all, Due to the lack of ventilation under my subfloor, I decided to add some retrospective ventilation ducts behind kitchen units above the outside floor level. however after a few weeks I’ve pull the subfloor up and noticed the duct opening under the floor is soaking wet which I assume is...

Hi all, We have a wall of floor to ceiling tall units with a couple built in ovens. We plan to completely box the units in all the way around so the units appear built into the wall, however we will be blocking all possible air exhausts for the hot oven air. What issues could this cause me in...

Hi all, I'm fitting a new free standing bath tap which has the flexible tails pre connected with a female 1/2" connector on the end. I have my hot and cold feeds under the floor. The maximum hole i can make for the tap is only about 50mm in diameter so impossible to connect (or disconnect in...

Thanks for your response. He used 7x2 joists at 300 centres. I wish we used 7x3. It'd just about OK with regs. Building inspector requested we double the joists under the bath so we installed 7x3 half way directly under the bath too which sit in the web of the steel. I also made it very clear...

Yes it does because the joists are tied to the wall... I'm just worried that because where the joists sit in the web of the RSJ and aren't secured from moved towards the wall, they could over time move in that direction.
