Pond paints are significantly less expensive than fibreglass and roughly comparable with a basic EPDM or butyl rubber liner. However, a basic liner can be very tricky to install correctly without creases and folds, which are prone to harbouring parasites. A box-weld liner is a much better option, but that comes at significant additional cost and is only really suited to regular, straight sided ponds.
Paints, and indeed fibreglass, are much more versatile. It’s also important to note that all paints are not equal. At RESIENT, products are not formulated based on cost, but on performance. We are confident that, if paint is the best option for your pond, then RESIENT Pondsafe is the best paint you could use.
