Chemical spryer

Guys I’m trying to put together a sprayer (12volt) that I can use to seal pavers and apply other chemicals like f9 barc. Or is there anything off the self you would recommend. The one seal n lock sells is 425 bucks and i think i can do better. I do have a fatboy setup for roofs but i think its just too big.

Thank you

I was thinking the same thing. A pump dedicated to other chemicals other than the roof pump. I dont see why a smaller pump wouldn’t work . Something like this Delux D5360 Diaphragm Pump would work I would think…

I was thinking alittle less GPM somewhere around 1.50 or 2
