Just thought I would post this for those who are interested. I noticed this question of how to seal surfaces gets asked here from time to time so this is how I have been doing it for 20+ years with no problems. I do seal some contract emulsions the same way if needed. Makes things easy with premium paints. It's a cost effective way to seal at under £14 for 5lt.
