Ask the paint chemist
Keith Harrison, the chemist at Newlife Paints knows a thing or two about paint. He recycles waste trade paints, modifies them, tints them and the water-based paint for walls, ceilings and woodwork is then sold to trade and DIY outlets nationwide.
I have a “simple” question for a paint chemist. What do you reckon is the approximate % of actual water in 1 litre of vinyl matt emulsion?
The reason I ask, nobody seems to know off the top of their head!
It’s not really a simple question. Emulsion paint is quite a complex mix with ingredients that include pigments, mineral fillers, opacifiers, thickening agents, flow agents, anti-foams, biocides, as well as usually vinyl or acrylic binder resin. The water content varies according to quality of the paint as well as type of paint i.e. matt/silk etc. but typically you are looking at 40 to 50% by weight.
If you have another question about the chemistry of paint, post it here, and Keith will endeavour to answer.
Newlife emulsion paint
When doing general painting and decorating, as a rule, I would use acrylic based emulsion only, but a while back I bought a tub of Newlife matt emulsion for a couple of large textured ceilings that had been previously painted in an ivory colour. To be fair, I thought the Newlife matt white flowed, covered and dried pretty well. Certainly comparable to something like Dulux Supermatt. It sells at a very reasonable price too.
Eco award winners
Newlife won some trade accolades last year as eco paint recyclers, and deservedly so. When 14% of all emulsion paint ends up in sheds or tips, I think that reclaiming and producing a mid range trade paint from that waste, has to make great environmental sense.
If you are a contractor with a quiet room to mist coat, give recycled Newlife paint a try out. It might give your quotes a new lease of life too.
