How to sandblast trailer for Spray Painting.


First step the trailer needs to have the old paint and rust removed so when applying the new paint it will adhere properly to the surface. You have 2 options;

1st option: Sanding with any kind of sander whether electric or pneumatic. This will be time consuming and hard work.

2nd option: Sandblast with sandblast pot or hand held gun, a pressure pot system is quicker. See before photo of a trailer we recently have booked in to be sandblasted then spray painted in Hammerdry Charcoal with and etch primer underneath.

Second Step apply an etch primer to the bare surface now the trailer has been sandblasted or sanded back to bare metal. Once the etch primer has been applied your trailer is now ready for spray painting. Be careful to mask all your lights, reflectors, wheels, any item on your trailer you don’t want spray painted. Always research the type of paint you are using to check for drying times between coats and best application procedures with air operated spray guns. See after photo of the trailer we recently completed, see the after photo of completed trailer spray painted, please note customer did not want top tradesman canopy spray painted.

Our customer didn’t want the top sandblasted or spray painted as he needs to repair the top section with welding some parts and fix the rust holes. Once this is done we can then get the top back to sandblast, undercoat with etch primer then spray paint. Keep checking our blog posts for updates and photo’s on the trailer tradesman top painted.
