Primer/sealer Or Sizing

Im a painter/paper hanger for about 22 years
getting ready to hang some yard goods in about 70 bathrooms (hotel)
new wallboard. drywaller says they should use a clear sizing on the new rock?
no primer sealer just clear sizing before vinyl installation. I've always used a primer sealer with good results, not sure of this idea, should I protest this suggestion, I have never used this clear sizing on raw sheetrock
only on previously painted sufaces, although I have sized walls with thinned adhesive before but it's been several years.

thx as always for any help

Re: Primer/sealer Or Sizing

You mean that somebody still sells sizing? Yeah, I thought that stuff was for rock hard plaster and figured it was long gone. I don't hang paper myself but I think you should do this: read the instructions that come with the paper and use what they say to use. Are there any wallpaper directions that still actually say to use sizing on drywall? I'd be curious.

Re: Primer/sealer Or Sizing

As was posted sizing is for plaster. You should prime raw sheetrock witk a suitable WALLCOVERING primer.

Re: Primer/sealer Or Sizing

the rule is use clear over previously sealed walls such as painted or hung walls, for new drywall, a pigmented wall paper sealer work the best it serves as a primer and sizing. Just make sure its designed as a wallpaper sealer,if you use a wall board type primer your going to have use a clear over the primed area. E Z prep is pretty good if you can get it.
