Great customer service
Great customer service. I had a query regarding Zinsser Gardz and whether you can use it on top of previously painted surfaces, as it states on their website that it’s not suitable. I contacted customer service on Sunday, then early Monday morning I received a phone call from a very helpful lady who explained that I can use it on top of contract Matt emulsion after all, prior to painting a final top coat, she said they would be amending their on-line advice regarding previously painted surfaces, she was very helpful and reassuring.
