I trust it as much as Wikipedia, it is OK if you know the answer, but just need a reminder.

So all surfaces get a coating then? The ceiling will have as much on it as the floor.

I think, based on this formula, t=(2h/g)0.5, that better results would happen before plaster boarding. I also think that the higher up the machine outlet is, the longer the latex will stay suspended in the local atmosphere.

As is sciences want, it is not as simple as that. There are polar forces at work also. These can cause molecules to clump together, with H2O molecules forming a tetrahedral shape. This increases the effective surface area, which allows more water molecules to be attracted, it also means that smaller forces per unit of surface area can cause them to move. But I don't think we need to worry about that in a ventillation system. Probably a hole in the wrong place.

I am not sure, but would think, from engineered properties, that the polymers form longer chains, do not need pigments, UV stabilisers, are more flexible and use water as part of the curing, as opposed to just drying. When water based paints dry, the water molecules evaporate, leaving just the base matrix. That matrix, in the case of water resistant coatings, shrinks and replaces the positions that were occupied by water molecules with voids that are smaller than water molecules. That is what makes them water resistant, water cannot get in. How chemists actually create this is a total mystery as they have about 20 words, which they just rearrange into compound nouns, to make things that are incomprehensible.

To the best of my knowledge, a water based latex sealant is atomised, then finds it way out via any cracks, slots and holes. Now pure latex does not have a very long service life, maybe 5 years, but hybrid siliconised latex can last 30+ plus years. I suspect they use the latter as they are both pretty cheap materials.

I have now got 5G with Smarty (3) and have had 4G with them for a few years now. £16/months with no restrictions and never made a voice call, ever. I use a new 90 quid phone as a hot spot. Works very well.

Bit late to this, but as I live on my own, and my home hours vary widely (and always have), I have tried most heating schedules. For me, on E7 heating, the lowest energy usage is to just heat when I am in with a fan heater (my house is small and uses very little energy). There is a problem with this method, and that is high relative humidity and condensation. I manage this with ventillation, but is does need to be managed. Until last winter I used my storage heaters (they work well as I set them up to work properly and despair at people at work who won't set theirs up properly). This eliminated the condensation problem, and gives me an evenly heated house. The financial cost was similar, so may go back to it after this winter. Storage heaters, once set up correctly, deliver thermal energy in a similar way to a 'wet' heating system set to a low flow temperature. Always remember that temperature is not energy, it is the way that it is delivered that is important.

I am close by today, but don't fancy the 7 hour drive back in the dark.

Do you mean the nacelles? If my 35 year ago experience in composites is anything to go by, then it could be, in part, material prices. I had a run in with ICI about chemical prices becuase I could get the components made in India, then delivered to any European site, cheaper than I could buy the materials. The Indians were using the exact same materials, made in the same plant at Teeside. Out of spite, and because EU free trade started, I changed to a German made polymer.

I don't buy any of the biscuits.

Happened once, along with Christmas. Don't beat about the bush, say what you really feel. (I live in a Duchy)

No shit Sherlock.

I think the public should be smart enough to realise that nothing happens quickly. I think the real frustration is the changes in policies. It makes it impossible for any infrastructure planning. This may be a tactic that the denationalised companies use, do nothing until there is a crisis, then steamroller the government into getting their (the companies) way.
