Painting Problems. Need Urgent Advice, Thanks!

Sorry for double post in the Ceiling sub-forum as well

Hi All

I am currently doing some minor reno works for my house. One work is to re-paint the master bedroom (one side is brick wall and the other side is gypsum board). This is almost done where the wardrobe and bed frame have already been attached back to the wall.

I have specified to use all Nippon Paints product. To my horror, I realised that the contractor paint a layer of oil-based sealer (not from Nippon) before painting the Nippon paint. I have 2 concerns here:

- the Lead content in the sealer! I have looked at the Material Safety Data Sheet (MSDS) and this is not listed although the label on the paint can indicated the product contained Lead. So probably the Lead content is less than 1% or so and not required to be declared in the MSDS under the law.

- the different brand oil-based sealer may not work well with the paint

My main concern is the Lead. Should I be really concern and get this rectify or am I overreacting!? Fyi, I have young children in the home which is why I am very concerned.

Thanks in advance for any response.
