Applying two coats of stain to your hardwood floors will result in darker tones; however, this may be necessary to obtain the stain tones you wish for.
To achieve a darker stain color, use coarser grit of sandpaper (#150-#180) on the last sanding you do prior to staining. This will help the wood absorb more color. You can also leave the wet stain on the wood for longer before you wipe away the excess - sometimes as long as 15 minutes. This may help you achieve a deeper color. Note: check the label directions for the particular stain you're using to see the maximum time you can wait before wiping off the excess stain.
