How to patch timber door?

I have a maple front door that required a bit of patching in some areas. I bought the timbermate wood filler in maple, hoping that it would be a colour match, but it looks quite red in comparison to the door. When I sand it back and revarnish will the colour be closer to the rest of the door, or should I be buying another wood filler that might be a closer colour match? If anyone knows what colour the varnish might be, that would also be great.

Re: Timber door patching

It’s important to understand that the colour of your finished maple door is not the same as raw maple timber @NicoleDIY, which is what the Timbermate filler is trying to replicate. Your door almost certainly has a stain and varnish over the top, which alters the colour further. Timber fillers are always a single, solid colour and can’t mimic the natural variations and grain of real timber, so patched areas will almost always stand out to some degree.

 

If you sand back the filler and revarnish, the colour may shift slightly, but it’s unlikely to perfectly match the rest of the door. For the best results, you’d need to sand the door back to bare timber, apply the filler, then re-stain and varnish the whole surface. Even then, the patched areas will probably remain slightly noticeable. If that level of restoration isn’t acceptable, painting the door may be a more effective solution. Otherwise, using the maple-coloured filler is about as close as you’ll realistically get without undertaking specialist timber repair.

 

Please let me know if you have any questions.

Re: Timber door patching

Thanks Mitchell, really appreciate your detailed advice. Do you by chance know what stain/varnish the door might be or how I could go about finding out?

Re: Timber door patching

It’s really very difficult to determine exactly what stain or varnish is on your door just by looking at it @NicoleDIY. From your photo, it seems to have a brownish tone, maybe in the oak-type range, but that’s only a rough guess. Even if you could get a sample and try to match it, it’s almost impossible to achieve an exact match. Stains behave differently on different timbers, so a colour that looks close on one wood type can look quite different on maple.

 

For patch repairs, you’re almost always going to see a difference because the existing door has multiple layers of stain and varnish built up over time, while any patched area will have just the filler and a few coats of stain. Even lightly sanding and re-staining the whole door will only get you so far, because the patched areas will absorb stain differently and usually remain slightly noticeable. In-store stain samples are typically applied to pine, so they won’t give an accurate idea of how the colour will appear on maple either.

 

If your goal is a seamless, consistent finish, the most reliable approach is to sand the door back to bare timber and start fresh with stain and varnish across the whole surface. Trying to blend patches alone is very difficult, and in most cases, those repairs will still stand out to some degree.

 

If this were my door, I wouldn't even consider or attempt a patch staining on the filled areas. I would immediately sand back the whole door to bare timber and stain from there. It's a lot more work, but really the only way forward to get good results.
