Agree with Red. Under coat brush is cheaper & works. Live in the land of burdock & other prickers with long haired dogs one becomes a master. Oh & it also works on cats. Spring time it is the best for shedding wooly mini monsters.
The wood floor in the library room is a reddish color and I'm not sure I want to matchy-match it. I think I'd like a warm, honey-brown with a hint of red.
The floor is close to the Sedona Red color. I might go with Red Chestnut or the lighter Gunstock. However .... I stained my truck rails with Red Mahogany and they turned out super-dark, like Ebony! But in fairness, I applied the stain at night, with a sheepskin roller and didn't rub any excess off. The wood was pressure treated and had been outside / on my truck for more than 6 months of drying and weathering.
With this in mind, I will test-try some spots on the back of the bookcases before I commit to a stain. I might think the light red with darker red floor is too much. In that case, I'd probably lean towards Golden Pecan or Colonial Maple.
