Blocking sparks while welding/grinding

[cleverusername]

Basically I am looking for a way of stopping them damaging glass. I have tried thick cardboard and that worked quite well but it is difficult to get it to sit flush and the odd pesky spark got through.

So I need something that is easy to cover windows, will stop the sparks, won't catch fire and is cheaper than the ridiculously overpriced anti-spark paper, which is £100-200 pounds a pop.

Any ideas?

A friend of mine swears by this type of stuff https://www.ebay.co.uk/itm/Double-Alumi ... 1351428423

He recons its good, although he did get it for nothing.

I have used the thick cardboard method and the best way and cheapest way to make it cling is to wet it first. You need the crisp box sort of thickness otherwise if it is too thin it will disintegrate.

Ah, I went for really thick stuff, I assumed anything that thin wouldn't fully block the sparks.

I use cardboard taped in place

Always amazes me in the American car programmes I watch where they don't protect glass at all and sometimes they make a further change after spraying a car and don't cover anything whilst they grind away.

Whilst holding the grinder with one hand and not wearing gloves or glasses, it must be me that's ever had a grinder jump.

Gloves are a bad idea with a grinder..

So is having your finger sliced by a stray piece of metal or damaged disc,
gloves are required PPE for use with grinding according to HSE and there are gloves made especially for use with grinders and if the guard is on correctly there is minimal risk of the blade catching the glove and if it did it will only score the glove rather than slice your finger.
