Answer: 
It can be used indoors but the odor takes a day to dissipate. I'd highly recommend using this indoors only on days when you can open windows and ensure a high degree of ventilation. Use fans to exhaust the work area.

I am certain it can. It dries clear but I doubt it is very easy to clean up if you spill it on other stuff. Suggest use a small disposable cup and/or paint tray to work with product.

Smell is fairly strong but goes away quickly after it dries. I think the product is similar to stuff that they put in fingernail polish to harden it. I didn't notice any smell next day but my project was in well ventilated area.

Yes, this can be used inside. The odor should start to dissipate after the 2-4 hour dry time.

Answer: 
If you want to spray a wood hardener on, Home Depot is not the place to get it at. Unfortunately, being that this is Home Depots review site, I cannot tell you where the best place is.
So, in a word, no you should not put this in any sort of a spray device.

Rated 4.9 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Stabilized antique apple crates I uses this liberally on 4 old apple crates that were starting to rot and had worm holes throughout. It stabilized and hardened the wood just as advertised, and the crates are very strong now. It did darken the wood, and it took two bottles to do all of the crates. It's quite watery, which means it penetrates deeply, but that also makes it fairly messy and hard to paint on. April 5, 2016
Rated 5.0 out of 5.0 by Minwax Wood Hardener Used this to stabilize wood rot on an exterior window sill and frame. Removed damaged material as best I could down to solid wood and then used an inexpensive paint brush to apply product to excavated area. The hardener soaked into the wood fibers and when dried the wood was no longer spongy. Completed the repair with Minwax High Performance Wood Filler. Shaped the and sanded before priming and painting. June 14, 2016
Rated 5.0 out of 5.0 by works well to stabilize spongy wood before filling or painting This review is being written 1/31/2016 for the Minwax 1 pt. High-Performance Wood Hardener, advertised and sold by Home Depot. If wood is rotting, you can often dig out the worst, then apply the wood hardener to stabilize what is left. Fill the rotted area that was dug out afterwards with Minwax two-part epoxy wood filler. I've used this extensively on window sills and other exterior housing parts with great success. Prime and paint as normal afterwards (oil/latex are both fine). Warning that the wood hardener is the consistency of water, and has noxious fumes. To apply, use a disposable cup and disposable paint brush. Protect the area as it can easily splash. Dab the wood hardener repeatedly to let it soak in. It dries quickly. January 31, 2016
Rated 5.0 out of 5.0 by Very good stuff Repaired a n exterior door with wet rot spreading due to improper pet door install by former owner. I started with a spongy portion of door I could easily push a screwdriver all the way through. I got out the worst of wet rot, then used hair dryer for a couple of hours to dry out the rest as best I could. I then used old throwaway paint brush to apply product to exposed wood. I think the most important thing i did was drill several holes on each side of door around perimeter of the rot and use small pet medicine syringe to inject product into drill holes. I did about 5 coats. Rotten area went from consistency of wet Sunday newspaper before to knock on wood solid after. Plan to finish repair with a 2 part epoxy type wood filler now that I have something solid to build on. Great product. It does leave white residue if exposed to water before painting as other reviewer said. January 27, 2016
Rated 4.0 out of 5.0 by Great stuff, but be sure to paint! Just completed repairs on rotted wood around an outside door, so no long-term reports yet, but that part went well. Very easy to use, dries quickly. While I was at it, I treated the bottom edge of the fascia above the door, as well as some areas of deck railing that were weathered. The product dried to a hard, shiny finish, so I did not bother to repaint or restain those areas. After a rain, I noticed small white spots all over the brown decking where I had treated the wood. There were also large white drip spots on the deck below the fascia I had treated. I was unable to scrub the spots off; I may try acetone to remove them. I believe water on the unpainted product caused the white residue. So beware if using this product on a nonwhite surface, and be sure to paint over it after using. October 30, 2015
Rated 5.0 out of 5.0 by Great Product I use this primarily as a stabilizer for heavily / overly spalted hard woods and as a hardener for soft porous woods. For small spalted crafts pieces, I soak them overnight in a large mason jar, or for larger pieces, in a custom made container. Once thoroughly dried, even spongy soft pieces are similar in hardness to White Oak. PROS: > Dries Quickly > Penetrates deep into the wood > Sands well after 24hr drying > Does not seem to affect glues when thoroughly dried. CONS: > Needs to be used out-doors due to very strong odor. > Quickly gums up sandpaper if not thoroughly dried before sanding. > When liquid, can dissolve any products that use Acetone as a solvent, especially with prolonged exposure. > Doesn't come in Gallon size August 21, 2012
Rated 5.0 out of 5.0 by Minwax Wood Hardener There were a couple pieces of railing out on my front porch that were starting to soften and eventually rot right through. I really hated to replace the boards just for a couple small patches. I looked this product up and decided to try it. I applied the hardener and within a couple hours it had dried. I recommend two coats, but even with one coat the product worked very well! The once soft patches are now very hard and durable. February 29, 2012
Rated 5.0 out of 5.0 by Minwax Wood Hardner I have used this product in several exterior jobs and it has stabilized the wood, and saved my having to replace that piece. It takes a finish fairly well, and saves a lot of work! June 3, 2010
