Yes, both products have undergone rigorous testing and are considered non-toxic, non-hazardous, non-corrosive, and harmless to humans and plant life.
Yes, no special precautions or PPE are usually required, and no heavy lifting is required to utilise PolyCom or DustChek in most projects. We recommend that you speak to your distributor for detailed information about your project's requirements, however.
For new builds where dust management is a serious concern, we strongly recommend both PolyCom Stabilising Aid and DustChek are used together. The two products are very much compatible, and the best results in surface stabilisation and dust control are achieved when both are employed in parallel.
