Product: J25 Day-Chem Aggre-Gloss

Non-Yellowing Acrylic Sealer-Gloss.

Purpose: J25 Day-Chem Aggre-Gloss is a formulation of 25% methacrylate copolymers in an aromatic solvent. Aggre-Gloss is a clear sealer that will not yellow under exposure to sunlight. It forms a tenacious bond to the concrete or masonry surface. The high solids formula combines properties of adhesion, flexibility and UV light resistance to provide a long lasting, water repellent concrete sealer, that is available in a glossy and non-gloss (satin) finish.
J-25 will seal, dustproof and enhance the beauty of new and old concrete, masonry and related surfaces. It is ideal for stamped concrete, exposed aggregate or masonry surfaces giving them a glossy or satin finish. A unique property of Day-Chem Aggre-Gloss (J-25) allows the substrate to breathe while protecting it from rain and airborne contaminants.

J-25 protects many types of surfaces:

  • Exposed Aggregate
  • Masonry
  • Block
  • Stucco
  • Cast-in-place concrete
  • Precast and prestressed concrete
  • Limestone and sandstone


  • Protects against rain
