My gas boiler has a horizontal exhaust about 15cm below the underside of a car port roof. Under certain cold atmospheric conditions the plume condenses into droplets on the roof underside surface. The surface appears to be made of MDF or similar and I would like to protect it from deterioration which may be caused by the warm, wet plume of exhaust gas.
Please can anyone recommend a suitable protective paint for this application.
TIA

I had this problem. I attached a stainless steel (food grade of course :-)) plate above the outlet pipe to deflect the pluming away .
Can you not sheath the affected area with something, eg pin a sheet of polythene or attach a sheet of arylic on there?

My first thought was to attach a sheet of laminate. It would need to be about 3m x 1m. I went to B&Q and Wickes today but neither couild supply anything suitable. Therefore I concluded that paint might be the simplest option.
Many makes and models specifiy at least 200mm for this clearance, however we better give the installer the benefit of the doubt.
You could try a plume diverter and throw it downwards at 45 degrees.
