Hi @Whiteley71,

It sounds like you’ve encountered a challenging task. Removing multiple layers of old paint can definitely be time-consuming.

If you’ve already tried paint remover, heat guns, and scrapers, you could consider using a combination of techniques to achieve the best results. First, a chemical paint remover can be quite effective when used properly. You might need to apply a few coats and allow time for the remover to break down the paint. After that, a scraper can help lift the loosened paint, though be careful not to gouge the woodwork.

If you want to speed up the process, a heat gun can also work, though be cautious to avoid damaging the wood. It’s better to work in sections and keep the heat gun at a safe distance. Once the paint begins to bubble up, use a scraper to remove it gently.

For stubborn spots, edges that are difficult to reach and the walls, you'll need to use a detail sander to smooth out any remnants of paint. Just be sure to keep the area well-ventilated and use the sander carefully to avoid damaging the surface underneath.

Older houses, particularly those built before the 1970s, are more likely to have lead-based paint. If you suspect the presence of lead-based paint, it’s important to wear appropriate PPE, including an N95 respirator mask, gloves, and goggles. Lead dust can be hazardous, especially when sanding or scraping.

Another concern with older homes is the potential presence of asbestos, especially in building materials such as textured ceilings, wall coatings, or flooring. You should have an asbestos inspection or testing done to ensure you’re taking the proper precautions.

Please let me know if you have any questions.

Thanks Mitchell, lot to think about. How can I tell if there is lead paint in the house?

For a 1960's house, I would just assume that all older paints before 1980 contain lead @Whiteley71. So, the top layers might have been applied more recently, but the lower layers are likely to contain lead. It is best to be proactive and just presume you're dealing with lead-based paint. You might like to check with your local Bunnings store's Special Order team to see if we can order you a 3M lead testing kit.
