I have sanded down and applied 1 coat of undercoat paint, should I apply a second?
I always apply two coats of undercoat and then two coats top coat. Stoneman external painting
Probably yes. You should make sure that the previous finish is completely covered by the undercoat before you apply the top coat.
Yes second coat would be best but sand lightly before applying undercoat
If first coat is not covered properly u can do second coat and then gloss
Hi, if you already sanded and aplied 1 coat of undercoat paint should be fine , but for best result is better to aply another one before the paint.
Me personally I would it wouldn't hurt
Yes to create good adhesion
