I have a Brisbane hardyplank house.
It has a flat zinculume roof of approx 170sq m.(? or is it unpainted colourbond or is it the same thing)
There is only reflective roof foil as insulation and no air space to add any more insulation to reduce heat.
I may spray paint the tin roof with refelctive paint to reduce the heat that is being conducted to the internal ceiling in summer.
1 Will I notice a distinct difference in transmitted heat as the advertisement tell me I will?
1A Are all reflective paints fairly similar or are there distinct difference in paints?
2 What paints can people recommend to use, or stay away from?
3 I thought I might spend around $600 on
an airless spary system(Wagner?) from Bunnings which has 9 liter container.Will it produce a reasonable/good job on walls and ceilings for somone who has no experience.( apart from practising on a 170 sq m of roof where looks will be irrelevent)?
4 I notice these units produce a few thousand psi, so can I use this to assist in pressure cleaning the roof before proceeding to paint?The roof seems clean with no rust and is 10years old
5 Will I need to dilute the reflective paint if a spary unit is used, and if so, wont that effect the chemicl compostion of the reflective properties of the paint making it less effective?
A 24 hour kennards hire of airless unit is $197 so with a few jobs over the years I think it may be better to buy a $600 unit than hire.
I will also have to paint 15 wooden steps.
I definelty want something which wont clog and is easy to use and clean
6 Will I need to use primer on the tin roof
Currently I live in a very remote area so i cant visit it a hardware store or paint shop to speak to someone in detail about paints or a spray unit.
Any advice will be gratefully accepted.
Thanks.
