Painting bare and very heavy wet dash render

[markjg123]

I need to paint a large area of bare and very heavy wet dash render. Not the best rendering job you will see I'm afraid, and using a variety of brushes and rollers has so far proved equally difficult. I'm using Weathershield smooth masonry paint and want any advice I can get on the best application method.

Trade is a bit thick, I still use it and just resign myself that three thinner coats (10% water) is better than two thick coats.

Time wise it's about the same, but with the thin coats the brush work is not quite so hard, the wet paint runs, the thick paint need to be smashed in to crevices.
On the bright side each coat does get easier.

A long haired roller and the more liquid paint might also give you some success.

Thanks for the advice.

I've been using the paint straight out of the bucket, so I'll try watering it down a bit. Using a roller is getting about 90% coverage at the moment. You're absolutely right about the brush work. It's time consuming and we're finding we have to jab the paint into some pretty deep crevices. I'm happy to put up with some paint run off if the job gets done quicker.

You will still have to dab in, but with the paint being thinner your be lighter with the brush. Have a bucket of water, and wash off over spill within a minute or two.
Follow the wash off with a bit of clean old towel for max removal.

Let me know how you get on and leave a bit more time between coats due to extra water meaning the paint will take a bit longer to cure enough for recoat.

Will do. Thanks again.
