Any ideas on how to cool a house in the tropics with out using A/C's??
Been thinking about getting the roof tiles sprayed a lighter colour (currently brown). Has anyone used this option and how much did it cost??
Cheers
I'm about to spray my roof myself.
So unable to tell you if this will make a cooler house.
Checkout nutech paints website and they have a new paint with teflon
guaranteed to cool the roof cavity. (NXT coolzone)
Your biggest problem will be trying to workout which paint manufacture and who to spray it.
After all my investigating I have decided to spray myself as the roof is just over 300sq metres and would cost to much to replace or have someone else do it for me.
I have employed someone to redo the pointing as this is a bit of an art to do.
Preparation is the key before any spraying and final topcoats.
What condition are the roof tiles in,are they cement or terracotta.
Its not a simple process as the roof restorer companies suggest.
I had to purchase a few old tiles to replace a few chipped and went to the
local secound hand building material yard and found many cement tiles which
had been painted previously and all peeling. I took one of these tiles to
nutech paints in Sydney and they advised me why this had happened and
again it all came down to prep and the wrong sealer being applied.
Do not believe anyone that claims there paint is self priming.
You need a sealer or primer depending on your condition of the tiles
then two coats of top coat.
A roof should not be painted in one day.
Nutech have told me to spray the primer then leave until the following day
for first coat and then the next day for final coat.
I have just spent 3 days cleaning my roof with a petrol powered water
blaster which used 15 litres of petrol and almost emptied my 10000 litre tank of water.
Almost forgot most companies and equipment hires only have available
the airless spray equipment with a 317 spray tip and I have been advised
by nutech to use a 523 tip.
