Cracked or peeling paint can occur on cedar siding for a number of reasons according to william feist of the western red cedar lumber association.
Removing peeling paint from wood siding.
Just look at the same trim after one coat of the primer and zero scraping or sanding.
However even the best routine of cleaning scraping sanding and priming won t stop paint from peeling if water gets into the wood.
You can usually get these out using a solvent such as paint thinner lacquer thinner or alcohol.
This is a great technique if you want to avoid sanding after scraping paint or you don t want to use chemicals.
Protect the siding from wind with a tarpaulin.
Moisten a rag or an abrasive sponge and scrub to get most of the paint then follow up with a pad sander to get the rest and smooth down the wood grain.
Removing paint with heat.
Sure this sounds like another chore.
Set up scaffolding at least 12 inches away from the side of the house you re stripping.
To use sandpaper or a power sander to remove paint.
If necessary remove any knobs hinges or other hardware from the wood being sanded.
With low vocs this water based binding primer is three times thicker than regular primers and locks down and hides peeling weathered surfaces to create a smooth white finish for your top coat.
You can also use heat to remove exterior house paint.
Scraping often leaves small bits of paint embedded in the wood grain.
Most paint dealers blame paint peeling problems on poor prep work.
Honestly this stuff is incredible.
You need that much clearance to hold the infrared paint.
When the wood goes through a series of wet dry periods the paint and finish are stressed and the paint can crack.
