I have had a look in Part B Volume 1 and cannot see the answer, it could be that I'm in a fuss and not looking hard enough. I have cased a 152x89x16UB on THREE sides with 12.5mm Gyproc Fireline. Well, the steel is actually encased in 25mm ply ( for some other reasons ) and then the fireline is...

Hi, I've got two buildings that are rendered and then have been sprayed with a coat of 'Thompson's One Coat Water Seal'. I want to put a colour ontop. Any suggestions of issues I might face or best products to use ? It was last sprayed over two years ago. The spray was only on the 'weathered...

I’ve got a turn of the century house. The cavities have the blown yellow insulation as well as old lime mortar bridging the cavities. Cut holes out on the brick work inside ( replastering house ), and tips on how to get this yellow beast out ??

I am doing a full house renovation ( rewire / replumb / skim / decorate ). I am attempting to avoid the expense of knocking the whole kitchen area down, putting footings in and then building onto the exact same footprint. At the moment the kitchen area is a single skin brick extension (...

Hi, I've got a few door ways that are quite deep. One example is :- Room A 12.5mm Plasterboard 25mm Batten 25mm Celotex 225mm Brick 25mm Cavity 100mm Stud 25mm Celotex 12.5mm Plasterboard Room B NOTE: The build up is odd, as it's a complicated junction that's having to take into account...

Hi, I've done a warm roof. But, I think I've screwed up a little. I've done 60mm over the joist and 60mm (the max) between the joist. All well and good. I've suddenly realised how **** PIR is from an acoustic point of view. Alas, Building Control are reluctant to allow me to throw some rock...

I've got a roof and I want to add a bit of sound dampening by using a double layer of plasterboard. As I'm a skin flint, I will use one of sound bloc, and one of normal 12mm. As far I understand when you put the sound boards up, you don't sit them 'tight' together, but leave a slight gap that...

Hi, I've got a Warm Roof 100m2. 8mm Slate Batten Breathable Mem Batten (holding PIR down) 60mm PIR 145mm Joists 60mm PIR between, held in with 50x25mm batten Vapour Barrier Plasterboard Skim Due to reg's, I am not allowed to put any additional insulation material between the joists. In...

I've had to drill 26 x 2 5mm holes in a load of steels. The first side took ages and I thought about the problem. I've attached a picture of how I did the second side. So, but using a thin bit of timber and leverage it was bloody easy !! Of course, I was holding the drill whilst drilling - I...

Hi, I've got a building being refurbished. We have a 40 ft roof that we need to cut and put on. At the mid point (ish) of the rafter we will be putting steel perlins in to support the load. At the two gable ends we have already placed the padstones (a little lower than we think we need) and...

We have an uneven concrete floor. We are putting stud work on it. However, to ensure the base plate is level, we are packering it level with plastic shims. The shims are essentially 500mm part and we are using hammer in fixings to secure. To help distribute the 'load' that will eventually be...

I've got an existing roof structure (see attached photo). The build up is: Slate Batten Roofing Felt Slate Rafters (100mm) Perlins holding BOTH Slate Rafters and Ceiling Rafters (50mm - 70mm) Ceiling Rafters (100mm) All of the rafters are essentially cut with only one good edge. This edge is...

Morning, I would appreciate some comments / feedback in relation to a slab that has been poured by a subcontractor. I've prepared the area with blinding/dpm mesh & concrete mesh men. It's a pour of 130m2 and it was to big for me to do on my own. Contractor was employed to supply men/concrete...

I'm refurbishing an old School Building. It has 9" solid brick walls. We are building an inner timber 'skin' that will A. Take the load of a mezzanine floor above (taking advantage of the height of the School), to give us a second floor. B. Allow us to comply with Thermal Regs C. Give us some...

I'm just about to buy a turn of the century property to refurbish. Alas, the bay window has been removed. I've spoken to my local brick supplier (Michelmersh) and they have quoted a 26 week lead time on a supply of what I want. I have to say, I did laugh. Can anyone see any reason why I...

My gut feeling is yes... However, I would appreciate other peoples comments. I have refurbished a turn of the century property. It's a mid terrace brick under slate with 65mm cavities - brick on both inside skin and outside skin. I've taken all of the internal walls back to brick and...

Hi, I'm tiling a wall in a Bathroom. Unfortunately, it bows in. It's only a small width I am tiling, perhaps 900mm wide, all the way up the wall. Think of a 'half-moon'. Now, I need to essentially 'pack-out' the wall a bit by, at it's worst point 30mm... I don't want to use my expensive...

I'm refurbishing a property in Eastleigh, Hampshire. It's got a lead supply pipe. We've dug a 2'6" trench for a new supply, alas I was not present when the inspector called. I was 1" out, so I've got to dig a little more - no problem. However, the inspector called when one of my "lads" was...

GGgrrr... Did a conversion and installed a multi-room Audio system (Systemline Modular) 3 years ago. However, about 2 weeks ago it failed. I was out of warrantee. Basically the power supply had died. I opened it up, all the capacitors had blown and leaked. I thought this slightly odd as I...

I'm not a painter by trade, but as part of the refurb job it's one of the jobs that need to be done. Now, as I've got a portable vac I use this with my sander and get great results and seem (to me) to speed up the prep work no end. Also, between coats and a higher grit level seems to really...
