Have been using this product and it's predecesor fir years. works great. The best thing is it's quick drying time. It's almost too fast in my low humidity mountain environment.

I have used this product for a while and find it a good base producing product. If I am using their milk paint in a project, and do two coasts of sealer, sanding between coats to produce a good base to work from. If your base is not smooth, it will show through the milk paint.

It took three coats to fill in the wood grain. It was easy to apply and dried in less than an hour.

I am staining maple interior doors a dark cherry. Should I use sanding sealer first?
Rich E on Sep 23, 2016
BEST ANSWER: The main reason for using sanding sealer before staining is to allow even absorption of the stain. You can also use shellac, just make sure it's dewaxed, and dilute it one to one with denatured alcohol. Both work well. I would try it out on a sample piece first before doing your doors.
can you use sanding sealer before stain?
Elaine L on Jun 2, 2016
BEST ANSWER: Geeze... I'm not sure Elaine. I used it to seal edges before paint. As I think about stain and its basic principles, I would not think that the sealer before stain would give you the kind of look you would want.
Can this sealer be applied OVER a darker, GF water-based dye stain to smooth the wood before gloss (High Performance Gloss) topcoats, and not take up or cloud the dye stain? Looking for an final, mirror finish on maple.
Kevin on Aug 14, 2018
BEST ANSWER: Yes? Just read the directions on your top coat before you use either product. For example; the GF enduro-var water based topcoat says to not use over sanding sealer. Just make sure all the products you are using are compatible.
Can it be applied using a foam brush or does it need a sprayer?
John Q on Aug 26, 2015
BEST ANSWER: I'd go with a sprayer for sure. I have not been successful using a foam brush. The foam brush will leave a lot of air bubbles in the sealer and they don't go away as it dries.
Does the sand sealer help stop the grain from raising? Fast build?
Bob B on Jan 10, 2018
BEST ANSWER: Yes, it does. It is thicker than you might imagine...so it really does fill in the pores of the wood and allows you to get a great finish.
If I use a grain filler do I need a sanding sealer?
Tim R on Feb 24, 2017
BEST ANSWER: The answer depends on the coat you put on next. And the answer is simplest if you stay within the General Finishes family of products. For an opaque coating, the Milk Paints produce a very nice matte finish in various colors. These paints are self-priming, so you really don't need a sanding sealer. For clear coatings you can use High Performance Polyurethane finish which is a clear finish good for lighter woods. I have used the sanding sealer for this, but have also used the polyurethane by itself. For darker woods, the Enduro-Var finish produces a nice amber tone. General Finishes recommends using this as the first coat (for adhesion reasons), so you don't want to use the sanding sealer. These finishes can be brushed or sprayed. I have had the best results spraying with an HVLP system. Follow the manufacturer's directions for application. It is also good to do a sample process first on a scrap to make sure everything works as desired.

how to sand new wood cabinet doors after applying sanding sealer?
A shopper on Jun 16, 2015
BEST ANSWER: Sanding sealer is made soft and easy to sand. If you stained the wood first, you need to be a little more paranoid about sanding too aggressively and cutting through the stain in spots, or edges. I use 3M softback sanding sponges cut in half because they conform well and don't strip edges nearly as fast. And I finish sand by hand using touch and elbow grease. You're almost done, it's a good time to take more care and not rush. Use oblique lighting (look across the surface towards the light to reveal spots needing more attention). Practice on the backs or other places where minor blemishes are less visible.
Can laquer be sprayed over it?
RANDY H on Aug 6, 2018
BEST ANSWER: absolutely, I would use multiple coats of the sealer. Especially with the more open grain wood, oak, ash, jatoba.
Have fun
How to spray this thing? GF says it can be sprayed right out the can with 1.2-1.4 nozzle. I'm using 1.8 nozzle and still had to thin it to make it spray and when it did, it was very thin coats. When I sprayed it with 1.2 nozzle, I had to dilute so much that it was basically water and when I set the piece to dry on a little tilted surface (my floor isnt perfect), the finish flowed from side of the piece to the other and formed a puddle. What am I doing wrong?
