Flameproofing a cyclorama

[spinmaster1]

Hi,

 

We have made a 6m x 4m cyclorama by stitching 6 x 1m widths of cotton together and it looks quite good but the only probem is the flameproofing. I have bought 10 litres of MSL fire check but I need to know what the best application method is. I was thinking about a garden pressure spayer (the weed killer one not the pressure washer one) filled with firecheck then lie the cyc down on the floor and spray evenly accross it. Does anyone have any suggestions to this or any other ideas?

 

Thanks in advance,

Rob

The best way to ensure that you get complete coverage is to soak it.

A cyc that size should fit in a good size tin bath, but you may need more retardant.

+1 for soaking as opposed to spraying, then if poss dry in situ (i.e. rigged) with a plastic sheet underneath to protect your stage. Drying in it's rigged position will give you the added bonus of any shrinkage or tightening of the cloth improving the look of your cyc. You CAN spray with a garden sprayer but you inevitably miss a spot and it takes FAR longer.

When flame proofing large areas by soaking it is important to check the (total) weight of the cloth as much as the area. This will ensure you use the correct amount of treatment*. You may also want to compare this with the dry weight after treatment. The additional weight gained will also indicate sufficient treatment*.

 

*as per manufacturer

Minus 1 for soaking.....don't do it!

 

To treat any item safely you need to apply three coats to it in stages. Cover the surface evenly either by trigger spray, or by the weed killer pump action nozzle version the op was saying about. Let the first application dry before applying the second coat and repeat. Then the same for the third coat, once you have done this only then will you have a properly covered cloth.

 

By doing a soak, even though it goes against the laws of logic, you don't actually do as good a job as spraying.
