Construction primer really gives you something quick & easy to prime bare metal areas to prevent them from rusting whist you continue to undertake repairs on the rest of the vehicle - I use it both in a aerosol & a spraygun applied process dependant upon the area / panel sizes - it's mainly a red oxide type primer
Importantly you need to apply a decent couple of coats of it and take into account single pack / solvent based primers can absorb moisture - dependent upon your workshop conditions you need to consider air flow - ideally dry airflow - preventing condensation and consider the use of a dehumidifier - the primer can be just be sanded to create a key for your final 2k primer / epoxy primer coats - you could always consider brushing on / rolling an epoxy primer (which does not absorb moisture once cured) over your work areas - just mix a small batch up - wear the correct PPE including mask etc and only apply in well ventilated conditions (there are quite a few forum members who utilise this method with good results) - let me know if you require further info on the brands of construction primers that I use - Chris
Thanks Chris, yes please for the brands you use. Does PPE for rolling or brushing epoxy primer include an air fed mask, or is a combination of organic cartridges and very good ventilation sufficient?
