Contact cement in a gallon and a brush lay the carpet out an do half at a time us a regular blade and once you spread the glue out wait a min and let it take up then lay carpet out then use a 2x4 with a rag wrapped around it and start in the middle and work your way to the sides then all the the air bubbles should be out don't go to heavy on the glue because when you lay the carpet and use the board it will come threw the carpet and you will have a big fuckn mess and a good in door out door carpet works good cheap shit ain't good good shit ain't cheap and after all you don't need that much so don't go cheap
