Loxon XP® Waterproofing Masonry Coating

Description

Ultimate High-Build Direct-To-Metal Concrete Armor

Sherwin-Williams Loxon XP® Waterproofing Masonry Coating represents the absolute industrial standard for protecting structural concrete, stucco, and brickwork from severe climate degradation. Spreading noticeably thicker than standard exterior paints, its heavy elastomeric body creates an unbreakable, weather-resilient defensive skin that completely seals out driving rains. It protects porous masonry cores from water saturation and subsequent rebar corrosion without requiring a separate priming stage.

Best Used For:

• Exterior high-rise commercial structures, active warehouses, and industrial complexes
• Above-grade exterior stucco, tilt-up concrete panels, and poured concrete walls
• Split-face block, concrete masonry units (CMU), and architectural brickwork
• New, fresh masonry installations showing high-alkali levels up to pH 13

Key Benefits & Features:

• Dynamic Crack Bridging: Cures to a highly flexible rubber-like film that expands and contracts naturally alongside building settling and seasonal temperature spikes to prevent crack telegraphing.
• Hydrophobic Weather Barrier: Exceeds standard wind-driven rain resistance metrics, isolating porous concrete paths from severe water saturation and moisture migration.
• Micro-Porous Breathability: Formulated to ensure that while external liquid water cannot enter, internal structural moisture vapor passes through freely to stop blistering and flaking.
