Honeywell MS583WH5G Masterseal 583 Masonry Waterproofer

Product Description

The HONEYWELL MS583WH5G is a dry, polymer-modified portland cement-based coating engineered to seal and protect concrete and masonry substrates against water intrusion, dampness, and seepage. Formerly marketed as Super ThoroSeal White, this product delivers a long-lasting, semi-smooth decorative white finish while creating a durable moisture barrier. Sold as a single 5-gallon unit weighing 38 pounds, it is applied by masonry contractors, waterproofing specialists, and experienced trade professionals working on below-grade or above-grade concrete and block assemblies.

MS583WH5G is suited for residential and commercial masonry waterproofing applications where a surface coating must resist hydrostatic pressure, dampness, and general moisture migration. Typical installation scenarios include foundation walls, retaining walls, concrete block, poured concrete, stucco, and similar masonry substrates requiring a protective, water-resistant finish coat. Its white finish also serves light decorative purposes in addition to its primary protective function.

Key Features

• Polymer-modified portland cement formulation for strong adhesion to concrete and masonry
• Resists water intrusion, dampness, and seepage at the substrate surface
• Semi-smooth white finish provides a clean, finished appearance after application
• Formerly known as Super ThoroSeal White — direct successor product for existing users
• 5-gallon unit size suitable for mid-to-large coverage areas

Compatibility

Designed as an OEM-style replacement coating for concrete and masonry waterproofing applications where polymer-modified cement-based surface treatments are specified.

Installation Notes

Application is typically performed by masonry contractors or waterproofing professionals familiar with surface preparation requirements for cementitious coatings. The substrate must be clean, sound, and free of oil, efflorescence, loose material, and standing water prior to application. Follow manufacturer mixing instructions carefully, as improper water-to-powder ratios will affect adhesion and water resistance. Refer to local building codes and project specifications for required coating thickness and curing conditions.
