HydroLock Masonry Protection Cream is a professional-grade, breathable solution designed for homeowners and contractors looking to improve the weatherproofing and thermal efficiency of brick, stone, and render walls. It offers a powerful, invisible moisture barrier that helps keep building interiors drier and warmer; however, it requires a clean, dry surface for optimal adhesion and performance.

No, HydroLock is designed for porous masonry and will not penetrate or work correctly on painted or previously sealed surfaces.
The product is designed for long-term protection, though efficacy can vary based on the porosity of the material and local weather conditions.
No, once fully cured, the cream is invisible and will not alter the natural color or texture of the masonry.
Yes, because the product is breathable, it is generally suitable for traditional masonry where moisture movement is important for building health.
Remove all dust, dirt, loose mortar, and biological growth like moss or algae using a stiff brush or a low-pressure wash, then allow it to dry completely.
Check if the masonry has been previously treated with a water repellent or paint; the cream only works on porous, untreated surfaces.
This may indicate the cream was applied too thickly or in cold conditions; use a stiff brush to remove the excess once the product is dry.
Ensure the surface was completely dry before application and that the ambient temperature was within the manufacturer's recommended range.
Ensure that the surface is completely dry and free from any algae or loose material before starting application. Apply the cream evenly using a brush or roller until the surface is saturated. It is essential to avoid applying the product if rain is forecast within 24 hours of application to ensure the cream bonds correctly with the masonry pores. For storage, keep the container tightly closed in a cool, frost-free location to maintain the formula's integrity for future maintenance or touch-ups.
