After watching many You Tube videos on how to paint concrete exposed to exterior elements I was going to seal the floor with PVA and then use off the shelf commercial brands to finish off and colour and I'm glad i didn't and made one more call to Promain . I was put through to Tony who advised me what to do with no hard sell and buy FLAG HEAVY DUTY paint FLAG acid etch and FLAG thinners. I have waited eight months since purchase and application to see how the products would deal with summer autumn winter and this spring 2021 till now 27th April 2022. A picture apparently tells a thousand words well here's a few before July 2021 up to today many thanks to PROMAIN and Tony we've enjoyed many days and nights on a FLAG PAINT FLOOR . NO PVA was used
