Not just the m² that is important, the periphery has to be taken into account. A 10m by 10m square has a periphery of 40m. A 1m by 100m has one of 202m

Quite simple and not too large. Have you thought of what you are going to do about finished edges (the ones you can see from the ground)?

Once the joints are layed up the final top coat could be done a few days later. How big is this roof and how complicated a shape. It is not to do with being waterproof, more to do with water absorption.

Would be my concern too if the whole job was to be done, and the low temperatures. Build a decent shed, you know it makes sense.

As far as I know, the fake stone pillars are still outside the entrance of the Heathrow Excelsior Hotel, made them in 1984 (hotel has been renamed).

1.22 by 2.44 (8 by 4, the world is built from it). The trouble with either just coating with resin, or putting up plain boards is that they will absorb some moisture. So much safer to get them coated properly first. It is hard to stress just how important keeping everything dry is. It is not unusual for a boat to have the gelcoat stripped off because of problems (known as osmosis, but is actually a mismatch of materials), then the shell is stored in a shed for months to dry out.

Not far from my family. You need a metre extra at least to work in. A metre all round us best. Should be able to do 4 boards a day if done individually, as long as you have somewhere to place them on their edge once part cured.

Yes. Where are you? I could do with a trip up country to see family. Have you got a large shed?

Managed to order my new oven and hob from AO. Apart from the teaser prices on eBay, they were also the cheapest, even when delivery was added on.

Fibreglass is a manufacturer of materials, it should be glass fibre, as opposed to flakes or powders. Bit like saying Hoover instead of vacuum cleaner, or even thermal mass instead of material thermal properties. Many different plastics can be reinforced with glass.

Yes, just make sure it is sanded to get a mechanical lock. I don't know of any videos. Could make one if you were closer.

Put at least 2 layers of 450gsm CSM on. You can leave it at 1 layer around the edges. Wait till fully hardened, lightly sand down. Get all the dust off, then apply topcoat, except for the edges where the joints will be. Then fit. Then lay 2 or 3 layers for your joints. The thicker the better as this will be 'resin rich'. Then, once fully cured, lightly sand, clean and apply topcoat. The topcoat will have a wax additive in it. So don't expect the normal resin to bind to it successfully. Also. By prelaying up the sheets you get good practice on using the resin.

How I would do it.

Basically yes. Damp boards can stop the resin curing where it makes contact, even if the outer is hard. This can lead to premature failure and a prolonged smell of styrene. Strong sunlight and high, or very low temperature can also cause problems. As I keep saying, if done right you can't get better, if done wrong, it gives it a bad reputation.

Because the resin needs an oxidising agent to link the polyester chains together. So it tries to get the oxygen out of the water, but it cannot break the strong H2O bond, so the water just gets dispersed in the free stryrene, which is carbon and hydrogen, and does not need anymore hydrogen. Or It just makes a sticky mess.

Tie a knot in the flexible pipe.

Can you tow it behind a Crapi

Sometimes people forget the really obvious. KISS

I think the issue is with cold spots, rather than the overall energy losses. Treat it the same as any other cold bridge, if you calculate it as a risk, then treat it as such, if you don't calculate it as a risk, and it proves to be one, then tuff.

Seem to remember that the CO alarm I fitted at my Mother's has to be a minimum distance from a gas boiler. They had a new boiler fitted as it kept setting off the council installed alarm. £8,000 later, lots of turmoil while fitting new pipes and radiators, the alarm went off when the system was commissioned. Council sent a man to fit a new alarm, same problem. Turns out the alarm was too close to the new boiler. £8,000

2 kegs of gelcoat weight about the same.

Shall just wait till New Year then,, will have the whole world of choice, and tariff free too. I have now decided to embrace the winning side. Keeping friendly with my Brexiteer neighbour as he has guns, one never knows.

Ah, I am after a new oven and hob, thought it was eBay/Amazon playing trick, because as soon as I placed order it went up in price or was out of stock.

Can you change the glazing unit only to 3g later on. How different are the frames really.

and you are about 150 m high.
