![]() If you still see imperfections then it’s fine to do a third coat – just wait for the second one to dry first. The idea is to go at a right angle to the direction in which you went with the coat before. Then it’s time for your second coat which will need to be spread with a trowel in a horizontal direction once it has gone tacky. Start at the top corner and pull the knife vertically downwards, stopping around halfway, then, once you have rolled the joint compound on the bottom half of the wall, start at the bottom and pull the knife upwards.Īfter the wall is smooth, let the first coat of joint compound dry. And, don’t worry if you have to go over a few areas more than once. Keep a damp cloth and mud pan handy to wipe off any excess mud. Roll it on small sections at a time so that you can then smooth out the joint compound before it dries and try and keep it as even as you can.Īfter this first coat has gone on, you can then trowel it smooth with your squeegee knife. If you get it too thin, it can cause shrinkage and subsequent cracks, but don’t worry if this happens the first time, just get it a little thicker for next time. The consistency should be a bit like mayonnaise – just thin enough to roll on a wall. You can then roll on a slightly thinned layer of all purpose joint compound with your heavy nap roller. Make sure to let the sealer dry thoroughly too. Start off by rolling the whole wall with fast drying stain sealing drywall primer to ensure the joint compound sticks better to it.
