Non-Toxic Glue for Engineered Wood Flooring
This topic is giving me more grief than the complicated stuff!
Manufacturer strongly recommends our 8″ wide planks (5/8″ engineered wood) be installed with glue-down method. Locally everyone does glue and nail/staple which the manufacturer also allows, or floating. Climate is 6B, dry.
And it’s almost impossible to source fairly non-toxic glues (like the Bona 850/851). Full glue down is easier to get (ie Berger-Siedal Berberbond M1, and Mapei Ultrabond Eco) but there is one option for tubes for glue and nail I’ve found I could order from the UK that is on the manufacturer’s recommended list (Sika 52 WF).
First I need to solve the issue of whether full glue is better than glue and nail, or vice versa. Any thoughts on that? Our climate is dry with large delta T’s. But my house is super insulated PH, the crawlspace is house temperature. Then again we are allowing sun in the numerous windows and that will warm up the floors.
If anyone has product suggestions they like, I’d love to hear them. I will sort through to find ones that are low toxicity and don’t have any fungicides. (I am building the house to be mold-free and fungicides are actually worse for people who are mold sensitive. And I have cancer so the VOC’s have taken on new importance.)
The substrate is plywood.
