 The best shielding is either 1/8" mesh or 1/8" circles in a flat sheet, which you can put over the vents with at least 6" overlap all around. The holes in this are a little big, but should do OK at 2.4Ghz for 15-20dB or so: The best shielding is either 1/8" mesh or 1/8" circles in a flat sheet, which you can put over the vents with at least 6" overlap all around.

 The surface you are painting onto must not be porous otherwise the shielding will be compromised. This is unlikely to be a problem over existing paint and wallpaper, but would matter over new plaster or plasterboard. Yshield recommend you test a small area. If you get a silvery/shiny rather than a matt black finish, the surface is too porous and will need priming/painting/sealing. The surface you are painting onto must not be porous otherwise the shielding will be compromised.

-It also doesn’t make sense to put Yshield over paint that is flaking or surfaces with cracks. I had both of these issues with my bedroom ceiling, but coincidentally had just fixed exactly the same issues in another room. For fixing the slightly flakey/porous /chalkysurface, I used a specialist paint, Zinsser Peel Stop - [[http://www.rustoleum.com/product-catalog/consumer-brands/zinsser/primer-sealers/peel-stop-clear-binding-primer|binding primer]] (My experience with all Zinsser products has been great. they aren’t cheap but they do work). Once that was on, I used a specialist ceiling paint to deal with the cracks: [[http://www.amazon.co.uk/Polycell-CFCSM25L-Crack-Free-Ceilings-Smooth/dp/B001GU2GA0|crack-free ceiling paint]] I had already used this successfully in the other room. It’s water-based and matt, but thick and sticky and covers up hairline cracks really well. I dealt with one bigger crack with acrylic filler. I also filled any cracks in the join between wall and ceiling with acrylic filler, which Yshield seems to cover well.+It also doesn’t make sense to put Yshield over paint that is flaking or surfaces with cracks.

-Yshield depends on carbon particles for its effectiveness, but if the tub stands still for any time, the carbon concentrates in the bottom, so mixing is very important. I wouldn’t want to do it by hand, and I used a thing like this, which fits in my Bosch cordless drill/driver: [[http://www.amazon.co.uk/Silverline-868687-Mixing-Paddle-Plated/dp/B000LFZ02W|Mixing-Paddle]]+Yshield depends on carbon particles for its effectiveness, but if the tub stands still for any time, the carbon concentrates in the bottom, so mixing is very important.

 A lot of mixing is also needed to get the fibre additive evenly distributed within the paint. I used a whole jar of the fibre additive for each 5 litres. It’s black, sticky and fibrous and sits in clumps in the paint unless you mix it in very well. Again, I wouldn’t want to do it by hand. A lot of mixing is also needed to get the fibre additive evenly distributed within the paint. I used a whole jar of the fibre additive for each 5 litres.

 Covering it:- only certain types of paint can go over the top of it, so I’ll be doing some investigation and testing. But the finish is very soft and marks very easily, so needs covering up otherwise is likely to become damaged.  Covering it:- only certain types of paint can go over the top of it, so I’ll be doing some investigation and testing.
