would suggest you to look out for Emalsan Matts of FRP(fire reinforcement plastic) which would cost you approx 130/- a kg, along with this you need G.P.Rasin which is general purpose rasin(chemical), which would cost 100/- a litre.
you need FRP 2- to max 3 kgs *130= 260/390
GP Rasin 4 to max 5 litres * 100= 400/500
paint brush for rasin = 80/-
