How To Paint a DECK the Right Way!

What happens here

A viewer asks about applying latex paint over oil-based trim. Chris discourages using oil-based trim paints due to smell, VOCs, cleanup difficulty, and safety hazards (spontaneous combustion risk, which he illustrates with a personal anecdote). He highlights that modern water-based trim products are superior in durability and non-yellowing properties. For applying latex over oil-based surfaces, he advises scuffing the surface and priming it, or if spraying, masking off the walls before spraying the trim. He emphasizes the benefits of water-based coatings for deck applications, citing better fade resistance and adhesion, and easier recoating.

Goal: Chris advocates for water-based coatings due to environmental benefits, ease of cleanup, and superior performance, particularly for trim and decks.

would you do the same so that's another good question now we're getting back to oil based products I don't know why anybody would paint their trim with all these products now and now you have trim products there's far superior to all base products in a vault yellow oil these products will yellow over time which is discoloring and so you're not gonna be able to touch them up you know after several years and they suck and yellows very quickly so when it comes to adhesion there's products out there that are just as good as oil based products products that spray low and level when you're spraying just as good as always if you're brushing your trim you know oil-based still has that ability to level and flow out really well but but he's spraying so he's getting the overspray onto the walls yes that will be an issue you get the over span of walls and how you're putting the latex over the top and we'll base well the paint out sometimes um you could if you're you really would need to go scuff that up or a prime over it or to me if you really wanted to go that route you need to mask your walls off spray your trim but I highly recommend you know you should go a mess using water-based coatings you know for your trim day then no really nobody really uses they're really hard to find if you in the u.s. they're really hard to buy so um if you sprayed like emerald urethane on your trim and it got on the wall and you're gonna paint with nobody no no issue so mr. primont you don't have to issue no issue with latex paints get on your walls going back over the top of them with latex I suggest reinvesting your water-based finish before you semi-transparent color
