Steve's workshop - Painting the outside walls

Spectacular Steve.

Lots achieved today, folks.

Remember we were celebrating putting on the last piece of plasterboard? Well I had a call from my Sparks to say that if I wanted to use the 32A plug on my TS I would have to upgrade the cable. I couldn't get to my TS to see the motor plate and wasn't sure if I could change the plug to a 16A one. So yesterday I bought some 6mm cable.

The problem is that the access hole for the cable into was not very generous and it already has a lot of cable coming through it. We reckoned that the easiest way in was from the left, but the cavity is full of foam, so we couldn't just poke it through. So we cut a couple of access holes to furtle it through bit by bit. Then we made a couple of patches a bit bigger than the hole and cut round them, removing PB to make a rebate. The patches were then glued and screwed in and it all looks very neat. It will look perfect when it is painted.

Some pics:

So that was a lot of faff to get not very much further, but one good thing was that we took the opportunity to replace the PB to the left of the door. The power socket had been installed off-centre and it offended my eye. It now looks right.

We had a few bits of PB left and it was in our way, so we used some of it to blank off the windows.

We then spent a while moving stuff about and clearing up, we needed to clear half the floor in one go.

We have some heavy-duty polythene for a DPC.

We plan to stagger the joints on the layers of the floor components as well as we can, so we started with a piece of Jablite and then continued with half-width sheets all along the back wall

Then we started with a full sheet of OSB. This is supposed to be 18mm, but at least one sheet is 22mm at one end It certainly is not very consistent. We kept an expansion gap all round the edge

So we have laid about 50% of the DPC, 40% of the insulation and about 30% of the base layer OSB.

We've also had a bit of good luck today. The delivery man had a couple of boards on his waggon. It looked very good. "What's this?", I asked. "CaberShield", says he, "It's very good stuff".

So I rang up about it. It is a bit more expensive than the ordinary stuff, but it has a bonded polyurethane, non-slip, pre-finished surface. Given that painting the floor would probably cost a hundred or so, the price difference is not so great. So my plan is to use it. At 22mm, it means that I shall have a high-quality 40mm floor on top of the polystyrene, which won't need maintenance. I hope.

The lights look really good. What are they and where did you get them?

Terry.

I got them from Yesss Electrical. They were about 60 quid each IIRC. You don't get much for your money TBH. I forget the make, I'll have to go down and have a look in daylight. I still have the boxes.

The tubes are Phillips, 58W 6500K.

Thanks Steve, appreciate you taking the time to pull out the info and post.

Coming along nicely Steve! Have to admit the before and after shot posted by Greyorm does make the new structure look huge, especially when considering the view of the houses behind. Yet it looks even larger on the inside - I reckon you should paint it Blue and call it the TARDIS

[Brentingby]

I agree with StevieB but what an improvement!

 

[fiacha]

I'd be happy to live in that workshop !

I'd rather have a nice clean looking building at the end of my garden, than a direct view to the neighbours house.

Terry, before you go ordering any lights can we have some dialogue cos I need a couple myself and we can bung them on the same order for the volume discount. I know yours are a way off yet but I'll forget so this is an aide memoir. Ta...me

We had hoped to finish the floor base today, but it was slower than we had hoped. We spent a geological age clearing up and moving stuff to the back so we could do the front.

Although I have bought floor-grade EPS, it is rather more squidgy than I had imagined. But I also have 4 sheets of Recticel (which I always think sounds like a medical preparation) which is considerably more resistant to compression. So we laid them out in the areas where I plan to use my heaviest machines.

One of the things we discovered about the boards we laid yesterday is that they do not automatically lie flush. Although they have been stored flat they are not necessarily totally 100% two-dimensional and the thickness varies. Quite a lot. They are supposed to be 18mm, but I don't think any one of them is less than 20mm. It causes problems and yesterday's has blips of up to a couple of mm. So today we pulled the boards together with the odd cleat. It was a good ruse. You can see what we were up against.

We have some cables to get to the middle of the floor, so we cut a rebate in the insulation to take them.

So we have got this far and at least some of it is even.

Wow fantastic the build is progressing well have watched from day 1 I hate to think of the cost though but building it yourself must have saved a bomb very well done will continue to watch with envy

 

[RogerS]

Do you not have to derate cables if you are passing them through foam insulation? IE you need fatter cables.

As my concrete bases is not really flat enough to use as a floor directly I'm also thinking of using EPS under some form of flooring (like the sound of that CaberShield). I was looking a it in Wickes and the guy there told me I would need timber battens for the boards to res on as the EPS would not full support it. When I saw yo laying the boards I thought oh well, wha does the uy at Wickes know, but maybe he has a point, especially as you say with heavy machinery sitting on it.

[Steve Maskery]

Well a builder I trust says it is. It's called a floating floor. The Jablite site shows it being used in this way.
It will have 40mm board on top of it.

 

[kostello]

Extruded polystyrene has a greater load bearing capacity than expanded......

 

[defsdoor]

I bet you'll be able to keep that place warm with a 40w light bulb.


And when it gets really cold - you might have to turn it on.


Looks brilliant.

I might get chance to start on mine (far smaller and modest) next year and have loads of ideas and inspiration from this.

 

[Danny]

Looking good Steve, I've just finished reading reading this thread from page 1. I'm currently building a 2.4 x 4.8m workshop and your's already makes mine look too small and I haven't even got the walls up yet! :lol:

Do you not have to derate cables if you are passing them through foam insulation? IE you need fatter cables.

Technically yes, the de-rating factor for a cable passing through insulation for 500mm or more is 0.5, which is half the capacity.

I wonder how that fits vis a vis insurance companies and, say, any claim for a fire ?

If you can still buy one that is. :lol:

Don't disagree with any of the above, I was only reflecting on the fact you said it had more give in it than you expected and that you therefore substituted a different insulation where your heavy machines will sit.

[monkeybiter]

When I had my extention built I made the mistake of not interfering/researching enough and the floor was laid just on the Celotex insulation. It now has some movement in the areas of heavy footfall.
At some time in the future I will be retrofitting timbers to support the floor.
