STAR manufactures high-quality sealcoating additives that enhance and strengthen the natural qualities of our high-performance sealers. Choose the additive you use according to the needs and specifications of each project. Review our additive product bulletins and specifications to find the right material for your upcoming projects.

If you are unsure of the appropriate sealer and/or correct additive to compliment the sealer, don't hesitate to ask us for our best recommendation. In addition to manufacturing our own STAR products, we also apply our own products to pavements through our sister company so are well versed when it comes to seeing the results and longevity of our own creations. We can and will guide you along the way if you're looking for the ideal product that will provide the best results.
