hi,having problems with rough blemishes when plaster drys,how i plaster.
step1-ensure surface clean,remove loose debris.
step2-apply pva to surface.
step4-apply second coat when first coat starting to go off,usually after about 15-20 mins.
step5-smooth out second coat.
step6-apply water coat,find painting water over plaster when it going off again after about 20mins covers some of the small recesses.
step7-wet trowel off ecess water starting from top corners down,then top of wall down then side to side.
step8-fill over small bleamishes with watered plaster off trowel.
step 9-leave for about 20 mins and dry trowel off.
Problem i am finding is when the plaster drys there are small,rough blemishes dotted around wall.
what am i doing wrong?
