Quietboard or Sound Stop?

I have the HD Quietbrace or board, whatever HD calls it on mine, but only because it was close and cheap (As in I was too lazy to drive an hour away to order Homasote when the HD stuff was cheap enough to get all I needed for the price of one sheet of Homasote and HD was 5 min away.).  It's as messy as I hear Homasote is, but not as dense.  It helps with sound, but not as well.  I'd of gotten Homasote if I do it over again.

Michael,

Pink (or any color) insulation boards are not sound deadening. Home Depot used to carry a product called QuietBrace, which was an excellent sound deadening product and as far as my experience, as good as Homasote but at 1/3 the price. What HD carries now (at least where I live) is nothing like the QuietBrace.

If I were you, I would get Homasote.

By the way, whether cutting QuietBrace of Homasote, either can be MESS FREE if you use a knife. I always used a utility knife to cut Homasote, as for my previous five HO layouts many years ago. For cutting QuietBrace for my previous and my current O-Gauge layouts, I used a utility knife and a knife edge jigsaw blade for curves and angles. No mess and easy cutting.

This is the page of my thread that shows what I did.

Good luck!

Thanks to Sinclair and Alex for advice.  I actually purchased the HD product.  Saved a bunch of money with 4 boards.  I realize this will be a messy project, so I will use caution.  Great idea re: special jig saw blade. The HD shop I went to did not carry it, so I may try a larger one. I know I can get it on Amazon. 

Another question: Do you recommend painting the boards before applying?  I purchased a gallon of earth tone "oops" paint for $9 and may use it. 

Thanks again,

Michael

Alex,

Just wanted to let you know I used the knife edge jig saw blade that you recommended (HD did not have it so I ordered it from Amazon), and it was fantastic.  Cut the fiberboard like butter and very little mess.  Great tip.

Thanks,

Michael
