Ask Kevin: That magic primer

Kevin & Co.,

You mentioned a sealer or primer paint that can seal over old boards that contain formaldehyde, etc. What brand is that, please?

Thanks!
Byron Savage

Byron,

That would be Safecoat Hard Seal. According to livingreen.com, “when applied properly it is particularly effective at sealing in pollution or outgassing of toxic chemical compounds from surfaces.”
Thanks for writing,

Kevin
