The two sticks have a long shelf life but once mixed the resultant putty is at first soft and highly adhesive and then gradually hardens. Speed of hardening is dependant on temperature and at normal temperatures, 20-25C, Aquascape becomes semi hard in 3-4 hours, taking slightly longer at the surface when cured under water. Warming the mixed putty for up to 10 seconds in a microwave can accelerate the speed of curing.
Once fully cured Aquascape can be machined, drilled, tapped, turned, filed, sawn, sandpapered and painted if required and is heat resistant up to 130C. Aquascape will bond to any of the following materials: – wood, brick, cement, metals, concrete, rock, plastic, glass etc making it an excellent adhesive however it is not designed to be used as a thin layer bonding agent where a conventional glue is indicated.
If you have not used Aquascape before we suggest that you make yourself familiar with its behaviour before use within the aquarium. Mix a small amount and notice how sticky it is when first mixed then observe it over the next 2–3 hours. After half an hour it becomes rubbery and can be cut with a knife or scissors before becoming quite hard and tack free. Observe the change in colour when used under water. Overnight it becomes fully cured and sets rock hard.
