This product is a waterproof gel glue that protects fabrics by creating an oilcloth like finish. It can be used with most fabrics. I use it for waterproofing on the Retreat Bags I create. I lay the fabric RSD on a flat surface and coat the whole fabric surface. I reapply if necessary. Fabric becomes a bit thicker but can be easily cut or sewed through. When dry the fabric has a finish that is similar to oilcloth that is waterproof. I have applied this product for protection of any outside "bottom" of bag, inside for make up bags, quilted baskets, baby change pads, underside of double layered baby bibs, any surface I would like to keep waterproof.
Can be applied with the enclosed card or by using one of your own soft brush. I have applied this product to finished Retreat Bags that I have made on the outside by placing painter's tape to where I wanted the coating to stop, applied the product and once dry (couple of hours) removed the tape. I found it best to apply to inside surfaces before sewing together and this product also glues surfaces together and is difficult to pull apart once dry.
Once completely dry, the surface is hand or machine washable, transparent, odorless, acid and solvent free.
