How to Prevent Paint Bleed Under Tape When Painting Furniture
I don't know about you but there is nothing more annoying than peeling away painters tape to reveal a splodge of unwanted colour on your piece of furniture.
I use three (slightly different) methods to prevent paint bleeding under tape, dependent upon the look I wish to achieve.
On natural wood furniture
If I'm doing stripes/geometric design on an unpainted piece of furniture (I'm assuming you've already prepped) then I use a clear flat varnish OVER my mapped out masking tape. This then seals the edges of the masking tape thereby preventing the paint bleeding under. You can then paint in your colour(s) as normal. Just remember to remove the masking tape before the paint is fully dry. I normally starting removing it - at 90 degree angle - after 10 or so minutes.
I use Vintro's Extreme Varnish as you can use it as a stain blocker before painting and as a top coat. Love it.
On previously painted furniture
Say you've painted the base coat(s) on your piece of furniture white. Once fully dry (I would leave 24 hours), tape out your design using a delicate masking tape specifically for painted surfaces. Once complete I then paint over the edges of the masking tape with the white paint that was used as the base coat. When fully dry you can then paint your design with your chosen colour(s). Again remove tape before paint is fully dry and at a 90 degree angle.
How to paint a cabinet door in 2 differing colours (interior & exterior)
I find that when I'm painting exterior furniture doors a different colour to the interior this is a lifesaver. It even works on those annoying curved edges; yes, you Ercol!
Step 1: paint the lightest colour first (for this example we will use white again) and go PAST where you want this colour to end. If you need 2-3 coats for full coverage then do this first before moving onto Step 2.
Step 2: Once FULLY dry, attach the masking tape where you want the line between the two colours to be. Remember, you should have the white colour PAST the tape.
Step 3: Now paint over the masking tape edge where the second (darker) colour is going to be with the original base colour (white, in this example). Allow to fully dry.
Step 4: You can now paint the other side of your cabinet door and you won't have paint bleeding under. I do, however, feather the paint towards the edge of the tape so that I don't have a 'thick' build-up of paint where the two colours meet. As normal remove tape at a 90 degree angle while the paint is still wet (as previously mentioned around the 10 minute mark).
I really hopes this help and please do let me know if there is a specific question you would like me to answer.
Happy painting! xx
