Good Stuff, Iffy Directions
I’m a big GF fan, and this stuff is no exception—with the caveat the directions for use are wrong.
When thoroughly mixed, it is like evaporated milk, but does not impart any cast to the wood (raw maple in this case) and soaks right in. The directions on the can say wipe it off, let sit 20 minutes or so, then apply stain. However, while this method will give an even stain to maple, it effectively blocks the stain from coloring the wood! So, a better method is to sand to 150-grit, using good quality sandpaper, carefully following the grain (wear gloves! Finger grease will leave marks where you are staining). Then flow on the Wood Conditioner; with water-base products, those synthetic bristle brushes work great, clean easily, last forever. Let it soak a little, then wipe off excess. Stain as soon as possible thereafter, before the conditioner sets in to block the stain, following normal instructions. A dark stain may still be lighter than you wanted, so let dry overnight at a minimum, then lightly sand with 150 or 180-grit, dust, and re-stain. A bit of a pain, but with the blotchiness of maple, I don’t know a better way. Note we are not pre-raising the grain of the wood first, as that step is unnecessary with this regimen.

Fine Product
This conditioner does exactly what it is supposed to. It treats the grainy condition of basswood nicely, and the stain then goes on evenly. Without the conditioner, the blotchiness of basswood is too apparent and makes the final product look dirty. The lack of an oily smell and the easy, hot water cleanup also make this product very desirable.

Easy to use and worked well.
I had a small project with Red Oak wood. It worked just like it said it would. I put four coats of stain on top of it. Very even distribution of stain. Pleased with the results.

Pre-stain
I had never used pre-stain before so I wasn't exactly sure what to expect but it worked fine for the job that I was doing. I needed to stain Douglas fir a little more evenly than I knew that it would without the pre-stain and it worked out fine. Thanks for the advice.

How is this used? Do you let it dry and then apply the colored stain?
A shopper on May 22, 2015
BEST ANSWER: Let it dry and then apply the stain. It keeps wood like cherry and pine from getting splotches in it that block the grain pattern when you apply the stain. When you use it, pour some in a separate container and dip your brush in that. If you don't, the can will become contaminated from whatever your brush picks up from the wood and the conditioner will mold. Once it's dry, the grain will be raised, take a sanding block with 200 grit sandpaper and just make 1 or 2 passes over it. It will knock off the hairs and make the other coats smooth. Don't forget to follow up with 2 coats of water based topcoat. I wait about 1 hour between each application and can go from raw wood to completely finished in an afternoon.
I used this product on cherry and then stained, and did not get very good results. It is blotchy. I used a oil based stain, so dont know if that is the problem, but the can says oil/water formulation. Also how long are you suppose to wait from the time you apply till stain? The directions are not clear. It says dry time is 2-4 hours. But it does not state if that is how long to wait before staining. The YouTube video from GF, they guy only waits about 30 seconds.

Is this conditioner also recommended for GF water-based dye stain as well?
Monday317 on Aug 7, 2018
BEST ANSWER: I use it on hollow core doors which are very difficult to sand before I apply dye stain. It works very well.
I have built kitchen cabinets where the face frame is oak and I want to keep the natural beauty of it. Do I skip the stain and go from conditioner to finish coat?
