About this article
Did a quick before & after on this surface using primer and thought it was worth sharing. The difference in adhesion and finish was pretty noticeable straight away. It’s one of those steps that’s easy to skip when you’re trying to save time… but it can make or break the result. Curious what everyone else does Do you always prime, or only on certain surfaces? submitted by /u/intell_membranes [link] [comments]
