Concrete Hardener H35 5 Liters

H35 concrete hardener 5 liters

A versatile solution for concrete surfaces

We offer H35 Concrete Hardener, which provides a durable, consolidating and curing treatment for concrete and cement surfaces. Our concentrated formula, based on sodium and potassium silicate, is ideal for use on both new and existing substrates.

Optimum performance and versatility

With the ability to be diluted with demineralized or distilled water at a ratio of 1:2 or even 1:3 for poorly absorbent substrates, Concrete Hardener H35 adapts to a variety of needs. The product is suitable for exterior and interior substrates, providing high performance and abrasion resistance.

Dust reduction and surface protection

Our formula effectively reduces dust, increases hardness and surface resistance. With its low volatile organic compound (VOC) content (<30 grams per liter), the hardener leaves concrete hard and dust-resistant. Deep penetration into the concrete structure eliminates the risk of film spalling.

Protection against salt efflorescence

Concrete Hardener H35 effectively reduces salt efflorescence and surface sweating, which prolongs and improves the finish of polished surfaces. The product is ideal for use on terazzo and agglomerate floors.
