Hi fellow reno's,
I am starting on a project. Sanding back flaking paint on window/wardrobe trims. These are the tools am using. Plus have electric sander to do tougher jobs.
Solved! See most helpful response
Welcome to the Workshop community @amy2.
Are there any particular issues you are having with the sanding process that we can assist with?
On those detailed trims, you will find it difficult to remove all of the paint especially in the corners of the trims. In order to repaint the area, you do not need to remove all of the paint just the damaged and flaking portions of it. Once the flaking paint is removed and sanded smooth, you can apply an undercoat that will seal and bind the rest of the existing paint.
If you have any questions or need assistance, please let me know.
Thank you Mitchell. I am almost done with all the trims. Next step will be the undercoat.
It's great to hear you've made progress on your window and wardrobe trims. We can't wait to see your finished project as you are certainly taking all the right steps to ensure you get a fantastic finish.
Please let me know if you need any advice on painting the trims or if you had any questions.
Just a question. If I don't remove all the flaking paint, won't there be a distinct marking when re-paint. Won't be even in some places? I am pretty much able to peel off the flaking paint.
Any paint that can just be peeled off needs to be removed as it is not bonded to the underlying layers sufficiently. If you can feel the edge of the paint with your finger and it has a thickness to it then use you will notice the transitions after applying additional coats of paint. If you can't remove all the paint then I would certainly sand those transitions to minimise them showing through after recoating. There is a range of sanding sponges that can assist in getting into those tight to reach and profiled areas.
Thank you Mitchell that answer makes sense. Really appreciate the support!
Support and advice it what we are here for.
We're looking forward to seeing your amazing results as you're doing a fantastic job.
...still working on the paint. At the moment I am working on the trims on my back door.
I've been using 120grit sand paper. Have been suggested to use 180grit also. Which one is best for the job?
How will I know when it's smooth enough to apply the undercoat?
120 grit sandpaper will remove material faster and 180 grit will leave fewer visible scratch marks in the timber/coating. If you were to only apply a topcoat over the sanded areas then I would suggest 180 grit or even 240 grit so the sanding marks don't show through it. Since you are going to undercoat before the topcoat I think 120 grit will be fine.
A good way to tell is to run your fingers over the area. If you can feel the transitions between areas then it is likely to show through a single coat of paint. As mentioned this can be overcome by addition undercoats or two topcoats.
If you have some undercoat it might be worth doing a small test area and seeing how visible the sanding marks are through it.
I want to also congratulate you on your perseverance. I think you are doing a fantastic job. Most people would have just painted over it and had their coating fail in a matter of years.
