I am about to lay a Loose Wire underfloor heating system, should I use primer?

The need to use primer depends on whether a backer board is being used. If the heating element is laid directly onto a plywood or concrete subfloor, primer should be used. If an insulated or standard backer board is used, there is no need to use the primer as these boards are already primed.

The primer should be left to dry for 2-3 hours, until tacky, before laying the heating element. If you are looking for a high-quality primer, Instarmac have a full range of some of the best primers on the market.
