How to Paint and Seal Outdoor Brick Walkways in Troy College Campuses
Outdoor brick walkways on Troy college campuses—such as those spanning Rensselaer Polytechnic Institute grounds—require protective coatings to endure heavy foot traffic and seasonal weather influences. Begin by inspecting brick paving for loose or cracked units caused by freeze-thaw cycles common in Rensselaer County’s winters. Reset and repoint damaged bricks with a flexible, sanded mortar mix that matches existing mortar color. Clean the entire walkway with a mild detergent and stiff-bristle brush to remove dirt, moss, and algae accumulated during humid summers. Rinse with a low-pressure power wash and allow bricks to dry over several sunny days in Troy’s late spring. Apply a breathable, water-repellent masonry sealer designed for pedestrian surfaces, preventing water penetration while allowing moisture vapor to escape. Avoid acrylic paints that could trap moisture and cause spalling. For enhanced skid resistance, choose a sealer with built-in slip-resistant additives, critical for safety during rainy or icy conditions. Reseal walkways biennially—ideally in early fall—to maintain protection before winter freeze-thaw cycles begin. This process ensures Troy college brick pathways remain safe, attractive, and durable throughout the academic year.
