I am planning to use Coolglass white shading paint on my greenhouse - now for the daft question. I know it should go on the outside, but does it still work if put on the inside?
The reason I am asking is that there is no way that I am going to reach the top glass on the roof, either to put it on and definitely will not be able to wipe it off at the end of the year without probably falling through! How ever I can easily reach all the glass form the inside.
-
Can't you use a roller on a pole to apply it to the outside?
-
The problem is getting right up there and leaning over enough to get all the shading off.
-
Can I hijack this please & ask how easy it is to get off at the end of the season? Is it the best way of shading or is there another cheap, effective way of doing it?
-
Aside from the fact that coolglass makes the glass have a sort of matt finish, which wouldn't be the case if it was on the inside, (with regards to the suns rays) I would think it would still do the same job inside or out.
Just a thought, when you apply it, do you do the whole roof or just the side that faces the sun? My GH runs east to west, and only catches the sun on the one side, because by the time the sun gets round the other side, it's in the shadow of the house.
To answer Marymary, I believe it wipes of with a dry cloth at the end of the season.

I have found the answer to my question on the bayer website
You can apply Coolglass to the inner surface. The only disadvantage is that the product could be slightly messy to apply and remove. Another advantage to Coolglass over other shading materials is that when it rains the Coolglass becomes clear letting more light through which is then beneficial to plants. If it is applied to the inside then this advantage would be lost. Ensure that you cover absorbent surfaces if using Coolglass indoors, just as you would do if painting a room in your home.
Although I will lose the advantage of thereaction of coolglass in the rain , it is preferable to having a nasty accident in the autumn. Will try it on the inside this year and see what happens to the crops - will report back.

Solved my dilema -its wonderful how having a bath clears your mind - paint it all on the outside except for the panes I can reach, and then paint the very high roof ones on the inside. Light will come through when it rains and I won't worry about falling through the roof in the autumn!

As Pythagoras said........Eureka!!! (or was that some other Greek old fella?)
Well done TS
OOps, On reflection, it was Archimedes wasn't it?
-
I used coolglass the other week and it seems great.
Very easy to wipe off with a dry towel. Had to as it dulled down.
-
I wonder, would Windolene do the same job?
-
I suspect thet windowlene would disolve in the rain. Round at our allotments folks have been putting net curtains over thier greenhouses

Hi
I bought a net curtain which i put up on the inside of the greenhouse with those funny clippy things. Works well except bees sometimes get between the netting and glass and buzz a lot! But as you have the coolglass I would do as you are planning to and put some on the inside and some on the outside.
i wouldn't fancy taking off the stuff on the inside though (drips down the neck, arms etc). What about a soft broom for taking it off in the autumn and spray it on in the spring?
-
I have green builders debris netting thrown over mine, my seedlings are surviving so far.
The previous owner used fleece pegged on the inside and grew excellent cucumbers and toms.

Remember that, although we get a few hot days each year which we need to shade against, mostly it's LIGHT that we need?
A repeat, below - roll on or off in 30 secs.
-
Have put the coolglass on, on the inside on the high panes and on the outside on the low panes - it was needed as the temp reached the top of the thermometer- and that was just in April!
-
I'm currently using fleece clipped in place with clothes pegs. Easy to put on and remove, cheap and works a treat ;)
-
I bought one of those plastic marquee things when we first moved to this house, basically to use it as the smoking room.
It lasted one good wind, and no-one used it anyway, so I've cut out the mosquito netting panels and one is now clipped to the top ridge of the g/h with those mini clips thingies. I think it's letting enough light in but tbh the internal temps are still soaring this week so not sure how useful it is as actual shading !

yeh even with CoolGlass and the roof vent and door open it can still be too hot. :o
