I have searched the internet and watched a million youtube videos. However, my question is simple and not too complex.
Our subfloor was installed over 20 years ago, I would say not the best job from our subcontractors but eh? Anyways, we purchased underlayment for the sub floor
The question is this: The manufacturer states to use a portland non-shrinking cement. http://www.mannington.com/Residentia...tallation.aspx
Anyway, my question is this. What would be the best prep for this floor? Level sub-floor first then top with under layment (1/4 inch birch 5 ply smooth). We are using a staple gun with staples. Our sub floor is not smooth. It does have some low spots as well.
My concern would be the staples shattering the Portland if applied to the sub-floor, I hope this makes sense.
I have 33 boxes of Adura click vinyl we need to lay soon. I had to stop this project for a few months.
My dh wants to lay the underlayment then adjust to high/low spots? It sounds like it would be the easy plan. LOL
Oh, and we have tried to talk to carpet folks. The people who work for some of the local vendors do not know the difference between a sub floor an a underlayment. This is why I went online...
Thanks in advance! Do note I am gathering information for my diy kitchen/dR and bath project. I am not an expert and would like some opinion from folks who do it for a living.
