Kathleen Richter Staff asked 4 years ago

I am refinishing an exterior door. I have read that a wood conditioner can only be used on interior wood such as pine or alder. Supposedly If I do use it on my door before I apply the stain, sections of wood may not accept the stain because the wood conditioner blocks the absorbency of the wood. However, I want a even stain application. What should I do?

You can use a pre-stain wood conditioner on appropriate exterior wood without any problems. A conditioner is used on softwoods like pine or fir. It isn't used on hardwoods.

I can block the absorbency of stain if too much is applied or it is allowed to fully dry before applying the stain. Make sure to read the manufacture application instructions carefully as there are differences between manufactures.

If you have a door made from softwood then using a pre-stain conditioner is a good idea. Especially if the stain color is dark. Very light stains don't give the same volume of problems.
