How to Double Cut Wallpaper Without Cutting The Sheetrock Underneath - Spencer Colgan 

Spencer, is one of the best professional to explain how to do a double cut wallpaper.

Great job! Where Do I purchase the polycarbonate shield? Thank you.

I hang wallpaper in Amsterdam, i learn a lot from your video's

Great stuff Spencer .

Never heard of that shield in Uk, must have a look thanks for that tip

I hang wallpaper and have never seen that shield at any stores. Where do you get it ?

Never seen anyone do a double cut with a knife before. We use single edge blades in the Union

I'm based in Australia I have used a 1mm PVC x 50mm shield but it's time consuming with wide commercial wallcoverings as we normally work on a square metre rate these days I use a cutting tool from Muraspec which saves heaps of time.

Spencer while this works commercial installers use a seam buster or double cutter. They cost $5-$30 and they use double sided (4 edges) Swedish blades that are good for multiple cuts and you won't cut and damage the wall also you will need a 4-8ft professional straight edge with a handle.

I recently encountered a problem when installing 54 inch vinyl, at every seam where I double cut, the shade of the paper got slightly lighter in colour but only from looking at an angle, (from straight on it looked good) what might this be? My mistake in installing? Or an issue with wallpaper ? ( It was like this on every seam on a high number of wallpaper rolls) Thanks! .... I also reverse hung as stated in the hanging instructions.

Spencer how are where can I find this polycarbonate shield?

HOW do you work with that music blaring

So what store?

Keep in mind that in the “real world” commercial wallcoverings need to be hung FAST! Great tip for an “by the hour” installer but this technique would be too time consuming!

We used Swedish knife

i don't recommend anyone use a smoother as a straight edge. for walls of that height you should be using a 48 inch aluminum straight edge. this also doesn't require you to use a laser to make the cut straight(saves time) backing strip is mandatory yes but i find the plastic carries glue and gets messy and requires constant cleaning. we tend 2 use the side cut off's with the first sheet as a backing strip, pattern end facing glue to lesson glue absorbing then use the excess cut off from the previous double cut and so on. you COULD technically use the top and bottom cut offs as strips but those tend to be bowed slightly from the roll when hung vertically and could affect the seam overlap. put up the first sheet keeping whatever edge your next piece will follow not fully smoothed (inch and a half or 2 inch) add the strip and smooth, apply the next piece then double cut with straight edge. these days a lot of commercial taping is trash so before i make a run i measure where my seams are going and run a line of spray shellac or a bin primer vertical 4-5 inch wide. it gives you way more play time especially if your working with trimmed fabrics and veneers. also i find it better to use a quality 9mm utility knife (i recommend olfa XA-1) it seams up cleaner.

That's really good for getting payed by the hr you can really milk the job till the company is all out cash

No straight edge? Not how I was taught an also they make a knife that prevents you from cutting into the wall. 10 times faster. Just my opinion 🤷

Your just an average wall paper guy you just have all the top of the range tools ie if everyone had a laser I am sure everyone could do this not hard pal

man this is not perfection. I see on the video second part paper line. Should be invisible that line.
