We took all the best attributes of the 5505 - clear, non-yellowing, UV stable and made it into a satin finish water-based formulation. It is not overly glossy or shiny but will keep the patio protected from weathering while remaining breathable.
The 5500 is water based and VOC compliant in all 50 states making it a great option in areas with strict VOC laws.
One thin, even coat of the 5500 is applied with a 3/8” nap high quality roller.
Keep in mind acrylic sealers do not last as long as penetrating sealers and may need to be reapplied more frequently.
