I hope this will be enough, since there was a 2 litre right beside it, which I decided against buying and doing some calculations:
Assuming a 1mm application height, and 1000cm3 of glue(1litre) also overall ratios equate to 6:6 = 1:1 glue to water.
therefore a max. volume of 2000cm3 (1000cm3 x 2)
2000cm3/0.1cm = area = 20000cm2
because I am covering a square board width = length
square root of 20000cm2 = 100 x (root)(2)
which is 141(-ish)cm either way.
the board is 48'' by 48'' = 121.9cm by 121.9cm
so the mixture should easily cover the board
Enough Maths, here's the modelled board:
Anyways, here's the modelling finished, or just more rocks added:
|Where the two hilly boards meet|
|A small rocky patch|
|Another small rocky patch|
|A very tiny mound for the plain board|
|Will hopefully look better covered in sand|
All being well I'll apply the sand tomorrow, then spray black then then another glue layer can be applied.
