Sun light block on glass in greenhouse

I have been trying to get some paint so I can paint the greenhouse glass from inside to block out the heat of the sun. I have seen greenhouses blocked out with white . What is it ?



Go back to an old way, mix carbonate of lime with water to the thickness of paint. With a large brush paint on the inside of your greenhouse. Cover your plants with a sheet of newspaper to collect the splash.

Its a product called Coolglass. You mix the powder with water and spray it on the outside of the greenhouse. It is very effective and wipes off when the sun has gone!!

Coolglas comes as a spray can or sachets in most garden centres
