Description
POLASEAL PENETRANT HARDENER
Deep-Penetrating Masonry Strengthening Treatment
POLASEAL PENETRANT HARDENER is a premium, water-based polymer treatment designed to penetrate and restore strength to concrete and masonry surfaces. Engineered with advanced polymeric silicate technology, it reacts within the substrate to reinforce internal structure, improve durability, and extend service life.
When applied, the solution penetrates deeply into the masonry and deposits active polymeric silicates. Two key reactions occur: silicates chemically react with free lime in the substrate to form a stable calcium silicate structure, while remaining silicates fuse together to further densify and strengthen the material. The result is a more durable, resilient surface with enhanced structural integrity.
POLASEAL PENETRANT HARDENER can improve the strength of both new and existing concrete. The level of improvement varies depending on substrate composition and porosity, making test applications recommended to evaluate performance.

Preparation and Application
Surface Preparation
The substrate must be dry, clean and free of loose particles, oils, or any coating or substance that would interfere with penetration.
Application
Open a new container of POLASEAL PENETRANT HARDENER and stir for 1 minute to be sure that the product is homogenous. Apply the material by brush, roller or spray technique. Apply enough material to thoroughly saturate the surface and to insure that penetration is taking place. Allow at least 24 hours for the POLASEAL PENETRANT HARDENER to dry and for initial cure to take place before proceeding with work.
POLASEAL PENETRANT HARDENER is designed to be used ahead of repair treatments, such as patching, parging, plastering, painting, repointing, or waterproofing. POLASEAL PENETRANT HARDENER does not waterproof; therefore, it will not interfere with the bonding or penetration of repair materials. POLASEAL PENETRANT HARDENER will tighten and strengthen a substrate to greatly improve the performance of repair coatings.
Spray Application
For spray applications, use HVLP spray equipment.
Recommended Thickness
About 1″ depth

Limitations
Protect product from freezing. Do not apply to frozen surfaces. Do not apply unless the temperature can be maintained above 40°F for 24 hours. Application must be protected from precipitation for at least 12 hours. Shelf life is 24-36 months when stored in tightly sealed containers. POLASEAL PENETRANT HARDENER may cause a mild white staining on some substrates. This is not efflorescence and it is not damaging to the substrate or the effectiveness of the product. The staining is caused by a reaction with carbon dioxide in the atmosphere and the alkali component of the product. This produces a small amount of white alkali carbonate by-product that can be washed or brushed away.
Read the container label warning and Safety Data Sheet (SDS) for important health and safety information prior to the use of this product.
