Application data

3.01

Stir the gel to a smooth consistency. Spread a thick layer on to the work surface using the brush supplied. Allow the gel to remain for 50-90 minutes. Rinse off the reminding gel using fresh water. The waste water, after rinsing, contains acids and heavy metals, and must hence be treated according to local wastewater requirements before discharge. This can be done with neutralising agent or slaked lime. The waste water treatment should adjust the pH value of the clear water, pH 6,5-10, and precipitate heavy metals into a sludge which should be sent for waste disposal. Recommended temperature limits for application: 10°C - 40°C. NB. Do not pickle in direct sunlight.
