BIN vs SW primers and sealers


I have read numerous posts here about using Bin primers and sealers. I purchase all my paint products form SW (get a discount), but I also like what they sell. Never had any problems. What is the consensus about Bin vs SW when it comes to priming and/or sealing before painting? I will be painting a room that has been used as a playroom with markings (crayons, etc.) on the walls.

BIN vs SW primers and sealers


The real question is what are the properties of each , and when to use them.
SW has a number of primers, each take care of different kind of problems.

BIN is a shellac ( alcohol) base- and will hold back the worst of stains and odors. Hard to work with and smelly. Dries fast.
Oil primers will hold back almost all stains, some have better adhesion, and will usually handle well and level- but you have the oil odor.
acrylic primers and primer sealers are good for new work, with proper prep can do well on existing paint, dry quick and are low odor.

Try and clean the crayons (wax) off first using either cleaners that say work on crayons ( I think Krud Kutter has one) or mineral spirits. Then spot prime it with an oil primer or Bin.

SW sells a shellac primer that's a copy of BIN.

I haven't used the SW version, but based on the ingredients I can't believe it does anything different than BIN. BIN is so expensive that I went looking for an alternative (I have a discount account at SW.) Even with the discount it couldn't beat BIN from Home Depot, so I just use BIN.

The bugs have been on strike ( lac bugs that is- they are the guys that really make shellac).

Caused quite a price jump!

Crayons are wax. Might not bleed, but might roll off.
