When painting a room, how long do you wait before you can put tape on the fresh paint?

Fantastic DanH!

 

In your case, I would recommend 3M Delicate Surface Tape with the orange label.

It has low adhesion, so you'll get a straight line without the risk of pulling up your first coat.

 

As mentioned earlier, pull up your tape at a 45-degree angle to create a "break point."

 

This allows the tape to release much easier and prevents most tears in the prior coat.

 

NOTE:

Removing tape slowly and carefully watching the break point is essential.

 

Should you encounter a small tear, stop immediately and use a utility knife to release the tear from the tape.

 

Then use a very small dot of Elmer's Glue to replace the torn paint film.

 

The patch will dry clear and hopefully will make a repair that isn't visible when standing nearby.

DanH,

 

The question is what type of tape and for what purpose? If you are doing stripes and are using a 3M low tack blue tape to define the striped area, the answer is within a couple hours. If you are using mounting tape to which a fare amount of weight is to be added, the answer is probably several days. Acrylic wall paints get their full cure and maximum adnesion after almost a month, at which time they would be most resistant to being pulled off the wall by too aggressive an adhesive.

 

Hope this has helped

Hello DanH!

 

Paints cure at different rates.

 

The more solids, the less solvent ... the faster the paint dries and subsequently cures.

 

You'll notice that I mention both dry and cure.

 

Dry means ready to apply another coat or put into limited everyday use.

 

Cure means the paint has hardened to the point that scuffs will not scratch the surface or create blemishes.

 

What you want is cured paint ... before taping.

 

The can label will say, "Fully cured in XX-hours."

 

IN ADDITION:

Tape has at least three levels of adhesion: Low, Medium, and High.

 

Low is designed for delicate surfaces and recently painted surfaces.

 

Medium is designed for everyday surfaces on which the paint has cured.

 

And high adhesion is for surfaces like metal and glass.

 

FINALLY:

In most cases, I recommend either medium or low adhesion.\

 

Neither of these tapes will damage cured paint and the modern versions of these are manufactured with an emulsion that swells to grab the surface and prevent paint bleed under the edge.

 

LASTLY:

When removing tape, make certain to pull up at a forty-five degree angle.

 

This allows the tape to release at a diagonal and create a release point along the diagonal edge ... helping reduce the strength of pull at one point on the wall and preventing the paint or paper from tearing.

Thank you Pat.  That is the infromation we were looking for.  We are painting our bathroom 2 different colors.  The middle one third is a lighter color and the color we painted first.  Now we know how long we need to wait before we tape our border edges in order to put the darker color above and below the lighter one.

Thank you so much for this information.  It is gratefully appreciated.

Thank you.  We will remember that little paint patching trick.
