Mitigating the Effects of High VOC Sealant
Hello I had a question about VOCs in paint. If I use a high VOC plaster sealant but then paint and/ or wallpaper over with low VOC paint will that mitigate the effects of the higher VOC base layer?
Yes, a bit, although the worst period is from application until the surface becomes touch dry. The best thing you can do is to ensure plenty of ventilation for a couple of weeks after painting.
Concerns about painting a toddler’s room
Hi. We have a toddler and need to decorate our entrance hallway, stairs and upstairs landing. Walls to be painted but also a lot of wood and labelling…. questions we have are…is it safe for her to be in the house whilst this is done?
We can take her out for parts of the day but she will need to nap and also sleep at night etc. We will need to use those areas to get upstairs and it’s right outside her bedroom too.
Is it safe? We want a gloss finish but are there any water based paints that give that or only oil which is the more nasty one?
Lastly we need to paint her nursery ceiling. The walls were done previously. Do we need to use special paint or can we use something like the low voc breatheasy type and keep her out of that room for maybe 2/3 weeks?
Thank you so much! Emma
All domestic paints sold in the EU have to comply with legislation regarding the amount of harmful chemicals (VOCs) so, technically, any paint you’ll use is safe. Much safer than was the case 10 or more years ago, that’s for sure.
The real hazard is to those who use paints daily and the cumulative effect this has on their health.
However, it’s natural for parents to want to do as much as possible to protect kid’s from paint fumes (which all have an element of harm, no matter how technically safe they are supposed to be). So there are some products which are better in this regard than some others.
There are quite a few water based gloss paints on the market. They are often branded as ‘quick-drying’ and perform quite well although you don’t get such a ‘glossy’ finish. And, although they do dry quickly, they can take a while to fully harden (a couple of weeks, often).
As far as recommendations go I would just say buy the best quality you can afford as there isn’t much to choose between the different brands.
One thing to point out, in respect of preparation, is that if your house is very old there is a possibility that lead based paints may have been used at some time and care needs to be taken when rubbing down woodwork so particles are not released into the atmosphere.
It is many years since lead based paints were banned for domestic use; if your house was built after 1970 it is very unlikely, but worth mentioning. More info here
Wall and ceiling paint is less of a hazard. Auro Natural is one the best-selling brands of VOC free paint although it is a bit pricey compared to alternative brands. The ‘breatheasy‘ type paints are a fair compromise although not entirely chemical free. Ecosure is the Dulux equivalent which, again, has a low or minimal VOC content but not zero.
Your final comment has hit the nail on the head perfectly though. Ventilation is the key and if you can leave the room unoccupied for a couple of weeks this is about the best thing you can do, no matter what paint you decide to use.
And, sure, keeping your daughter out of the way while the painting is being done would be ideal but possibly not always practical. If you can ensure the house is well ventilated throughout though, all the better.
