Anyone used zinsser gardz as a sealer prior to skim? Just wondered. It's brilliant as a sealer over 100 year old chalky surfaces and would work great on contract emulsion to prime. Not sure if it's good to skim over through?
£26- 32 for 5lt and will do loads. Big HLS I used 2lt. I wonder if a coat of gardz then a quick Pva or just go on the gardz. I read some plaster over gardz when dry but rather hear what people think on this forum
