City Linemarking has been sealing floors for many years. Sealant applications are done almost every second day by our team. We have two main options for applying sealant, these are: Rolling and spraying. Depending on the condition of your floor and how porous it is we can advise you which way will give you the best results. Surface sealing is highly recommended after line marking to protect your new lines! The last thing you want is for dirt or cars with muddy tyres to damage your lines. With Sealing it’s as simple as hosing off the floor and the dirt will be gone!
