I have never yet experienced a one coat paint where only one coat necessary and this paint is no exception.
Paint for plastic gutters and downpipes.
The gutters look like new.
You will need to do a health check of the plastic that you re painting.
Oil based paint works very well on plastic and does not require a primer.
Things to consider before painting plastic.
Am very impressed with the result.
No drip gloss will flow out beautifully on plastic gutters and downpipes giving a far superior finish than msp the difference being an oil base gives more working time hence leaves totally no brushmarks and only one coat of paint required.
The condition of the plastic.
We had an extension built and now have exposed white plastic windows and waste pipes a brown pipe going into the drain a grey plastic soil stack and black plastic gutters and down pipes.
To make matters worse if you don t do the job right you will probably find that you need to re paint your gutters and downpipes long before you have to paint your house again.
Older plastics can be brittle so make sure they are sound before.
Paint the edges with a brush and the majority of the gutter and downspout with the roller.
Would the life of all this plastic be prolonged if painted and is there a special paint for the job.
The two common things some people get wrong when painting gutters is choosing the wrong type of paint and not preparing the surface properly before painting.
Dont use abrasives to clean it will show through something wicked.
Clean allow to dry and a couple of coats of gloss.
Replace any leaky gaskets and joiners on guttering and fix or replace any faulty furniture on plastic doors and windows.
Inspect your work as you go for runs and drips.
You cannot beat the appearance of new plastic drainage systems but it will lose it shine in about 4 to 5 years plus you wont have the problems of preparing dust being blown onto wet paint etc also joint failures will not be an issue as the seals perish go for new if the.
