I have pine hardwood floors that are very light in color. Can someone tell me if it's possible to stain it to look more something darker, more like Walnut? Also, please let me know how I'd go about doing this, steps, etc.

 

First off, pine hardwood floor is an oxymoron. Pine is a soft wood that dents easily when unfinished (and when finished sometimes) As far as staining it, if you have a large area, this may be a PITA to do yourself but it can be done.

You will first have to remove any finish or protective coating if any by sanding. For floors this is best done with a powered floor sander. Then for pine, since it is a soft and porous wood, it will need to be treated with a special product that will allow for stain to penetrate evenly. If this type of product is not used, then you will have a blotchy look where some areas have "taken" the stain and other areas have not, often times creating a dramatic difference and does not look good at all.

Once that is done, you may stain with you favorite stain. I like gel stains that can be wiped off for pine and have had good success with dark walnut stain from Old Masters. You can let it sit on the wood for varying amounts of time to achieve varying darkness.

Finally you will need to finish with some type of urethane. Several coats is best. Like I said, a PITA if a large area...but maybe worth it to you. I like pine by itself, it is a nice looking wood with a rustic feel when left natural and unstained. But everyone is different!

 

A lot of pro finishers that have been down the road before know, pine and maple especially are very hard to stain. So they use a tinted finish to achieve a uniform color. Trying to conventionally stain and then apply finish leave a very blotchy appearance.
