Paint bubbling on walls?

Question

we are painting the walls in our house with valspar satin paint and right after we put the paint down and it starts to dry, bubbles start to appear. why is this?

Answer 1

u should have used a primer first ...the paint ur using now is not holding to the previous paint .... sounds like previous paint has an oil base to it ....use a primer first ............

Answer 2

This could be the result of moisture under the paint.  (Did you paint a second coat before the first coat had a chance to dry?)

Whatever the cause, the likeliest solution is to sand the bubbles down until you reach the paint that is adhering properly.  Be sure to get rid of the sanding dust (tack cloth, damp rag, etc.).  If you use a damp rag, be sure that the area is completely dry before proceeding.  Use a primer (like "Kilz" brand) on the sanded areas.  Allow to dry.  Apply the finish paint, blending out from the bubbled area into the adhered paint area a few inches.  

Note: Some paints (inexpensive, or certain colors) may require the entire wall to be finish coated again to avoid lap lines (areas where brush/roller marks are visible even after paint has dried).

Hope this helps you.

Answer 3

The wall wasn't washed properly. Next time use TSP, it's a cleaner you'll find in the paint dept. It prepares the old paint to act like a primer at a molecular level.
