Royal Chemical Transparent Waterproof Leak Sealer

This Product is an advanced waterproof coating developed to eliminate water leakage without affecting the original look of the surface. Its low-viscosity formula penetrates deeply into tiny cracks, pores, and joints, forming a strong, invisible protective layer that prevents water from entering while allowing surfaces to breathe.

Designed for homes, commercial buildings, and industrial projects, this high-performance sealer protects roofs, bathrooms, balconies, exterior walls, tiles, and concrete surfaces from moisture, seepage, and long-term water damage.

Product Highlights

Fast Leak Sealing Action

The deep-penetrating formula quickly reaches fine cracks and hidden gaps, creating a durable waterproof shield that helps stop leaks at their source.

Invisible Protective Coating

Once dry, the coating becomes completely clear, preserving the natural appearance of stone, concrete, tiles, brick, and other surfaces without leaving stains or discoloration.

Reliable in Every Season

Engineered to perform in harsh weather conditions, the coating resists heavy rainfall, UV rays, heat, humidity, and cold temperatures without peeling or cracking.

Strong Bonding Performance

Adheres firmly to a wide variety of construction materials, including concrete, cement plaster, brick, marble, granite, ceramic tiles, natural stone, wood, and metal.

Moisture Control Technology

Creates a waterproof barrier that blocks rainwater while allowing trapped moisture to escape, helping reduce damp patches, mold formation, paint damage, and structural deterioration.

Easy & Safe to Use

Its user-friendly formulation can be applied with a brush or roller and is suitable for both professionals and homeowners. The non-toxic and non-flammable composition makes it safe for indoor and outdoor applications.

Application Method

Step 1 – Surface Preparation

Remove dust, dirt, grease, loose particles, old paint, algae, and any contaminants from the surface. Ensure the area is clean and dry before applying the product.

Step 2 – Apply the Sealer

Using a brush or roller, spread an even coat over the affected area. Ensure complete coverage, especially around cracks, joints, and corners. For vertical surfaces, work from top to bottom.

Step 3 – Additional Coat

For porous surfaces or areas exposed to continuous water leakage, apply a second coat after the first layer has dried for approximately 4–6 hours.

Step 4 – Drying & Curing

Allow the coating to dry naturally. The product begins protecting the surface within a few hours, while full curing and maximum waterproof performance are achieved after 24 hours. Avoid water exposure during the curing period.

Coverage Guide

Note: Actual coverage depends on the condition, roughness, and absorbency of the surface. Highly porous or damaged areas may require additional material.
