Taping over new paint

We painted our bathroom ceiling last night and now (15 + hours later) we're trying to paint the walls. We put tape on the ceiling, and in the process of trying to straighten it noticed that it pulled some of the new ceiling paint off. We used a primer and two coats of exterior paint for the ceiling. What can we do to prevent this from happening? How long should we wait?

We live in Florida, so it's pretty humid.

By the way, we used Porter Interior Latex Primer and Exterior Acrylic paint for the ceiling. The walls and ceiling had been skim coated.

It is seldom a good idea to stick tape over fresh paint. Latex paints often take a week or more to fully cure. An exterior paint will never dry as hard as an interior paint.

It s best not to use tape. A little practice with a quality brush will make cutting in a breeze. The peeled off spots should be spackled, sanded, primed and repainted.

Yeah, what Mark said...

I wouldn't put tape on a surface in my house any sooner than two weeks, a month in a humid house.

As mark also said, for just the wall->ceiling joint, you really don't need tape... just patience and a steady hand.

"Blue" tape

You do need to be careful for a couple of weeks or longer when taping new latex paints because they develop adhesion as the cure and curing can take about 4 weeks.

Drywall compounds are not very strong and masking tape can pull apart the drywall compound underneath the paint also.

Because of the above potential problems you need to use an easy release tape and carefully pull it off when you are done. There are a number of these tapes out in the marketplace, one popular tape used by painters and faux finishers is the "blue" easy release tape made by 3M.

Forget the tape. Its a crutch you do no need. The keys are a quality brush and quality paint and painting with the tips of the bristles. Spend more than a couple bucks on the brush. Its well worth the extra $$.

Same with the paint. There IS a difference in paints. Good quality paint goes on so easily and smoothly! You can't get that from a big box paint.

Painting with the tips of the bristles sounds silly to say. But most DIYers end up painting with the sides of the brush (too much pressure).
