I'm about to try Johnstones Aqua Water Based Gloss on a big job. It's advised that Johnstones Aqua Undercoat should be used but I have a large supply of primer/ undercoat. It's going on old oil based gloss.
Can I use this as undercoat or do I have to use Johnstones, thereby doubling the cost?
Anyone used it?
Thanks
