Can someone tell me more about a product called DragonBoard? Should I use it?

I want to use it as a backer board for tile application, in a home for a client who has chemical sensitivities.

It is always interesting when a question brings a new product to the table.

Such is the case with DragonBoard for me. From what is presented on their website, I would say that this product would suit your specification perfectly.

DragonBoard is composed of:

  • magnesium oxide,
  • magnesium chloride,
  • water and
  • a fibrous material (presumably to hold it together), and
  • does not contain any organic solvents, asbestos, oils or toxic components, or any heavy-metal salts.

The board itself will not provide nutrients for mold as well as:

  • provides a fire rating that meets or exceeds that of drywall,
  • is completely waterproof, and
  • can be finished with typical drywall finishing techniques and materials.

The last part is probably the subject of your next investigation, and I would recommend using a hypoallergenic drywall compound for finishing.

Best of luck on your project!
