Auro 301 Plaster Primer Reviews

4 Rating 5 Reviews

Low VOC Primer Auro 301 Natural Plaster Primer is designed for priming absorbent or uneven bare plaster before painting. Ideal for use on gypsum plasterboard and gypsum fibreboard and mineral interior plaster. Materials which are highly or unevenly absorbent, such as gypsum plasterboard, should be pre-coated to achieve a uniform painting result. This avoids uneven, dull patches on the walls. The best primer to use before applying dark colours onto new plaster. Auro 301 is a highly breathable primer, so ideal in older buildings and before painting with lime based or other breathable paint products. This non-toxic primer has a milky appearance that dries transparent. This is a concentrate that you dilute 1:1 with water before use. People with allergies or who are MI sensitive will be happy to know that, thanks to Auro's ecological choice of raw materials and compliance with the strict AgBB criteria on emissions (a German evaluation scheme for VOC emission from construction products), this product...

“I obviously can't rate it's performance as a breathable sealer as I have no idea yet but in terms of a product it did pretty much what it said on the label. As other reviewers have stated, by the time you dilute it in line with instructions, it is like rollering water onto your walls which takes a moment to get used to but a light touch with a short pile roller is all that is required. It dried very quickly. Applying paint after this sealer is a doddle. With the 50/50 dilution it is clearly going to go a long way - just as well as I have a big restoration project with a lot of newly plastered (both lime and gypsum) to seal ready for painting.”

“I have used this product on new plaster and it created a great anchor for the subsequent coats of paint. I used Auro 321 White and it looked good with only two coats of paint (after the primer went on). The primer is diluted 50:50 and is as thin as water at this point. So it's messy with lots of drips to catch and re-spread. It's necessary to work quickly yet thoroughly, to ensure that all parts of the surface have absorbed the primer properly. I didn't get all my priming done in the same work shift (what?), but it was easy to see where I left off - the freshly applied primer onto already-primed plaster left no damp mark, whereas on the bare plaster it did. Simples!”

“Easy to apply, very low odour, dries to a completely clear finish. You can tell which walls you've primed after by running a wet finger across the wall: untreated new plaster will instantly look wet, primed plaster will not change colour instantly and gradually darken as the water slowly absorbs. No problems applying Auro paints after priming with this onto freshly skimmed walls.”
