Pin bubbles

[Anorth]

Why isit sometimes i get little pin bubbles appearing? Isit because the first coat has gone off to much?

air -suction - small bubbles I know them as "blebs" sometimes you can hear , a similar noise to rice crispies , this is suction & creates "blebs" - leave them they go , MT Blister Brush are good to rid these also

You need to be clear on the difference between setting and drying, high suction backgrounds can result in blisters as can overworking the wall before it is ready, good timing the cure.

give it a hard trowel at the end and it flattens them out, like pm said its just suction from the background
