Discover the vital role of concrete felt bond breakers in successful concrete projects. This comprehensive article explains how these barriers prevent cracking, uneven surfaces, and adhesion problems that affect up to 70% of projects.

Bond breakers are anti-stick materials used on adjacent metallic or non-metallic substrates, such as concrete and steel. Bond breakers can be used to improve joint performance. Without bond breakers, the joint sealer tears apart to accommodate movement.

feel of the bond breaker treated surface as well as beading of water. Bond breaker can also be checked by rolling up a small ball like amount under thumb pressure. Extremely porous or rough casting slabs will necessitate successive additional coats of bond breaker to achieve a consistent uniform membrane of the correct coverage rate and

The non-membrane forming bond breakers can be further categorized into reactive types and non-reactive types. Reactive bond breakers usually contain some type of fatty acid in the form of a stearate. The stearates react with the calcium hydroxide (lime) …

Jun 7, 2023 · A concrete bond breaker is a substance used to prevent adhesion between two surfaces. In the context of concrete, a bond breaker is applied to the bottom of a concrete slab to prevent it from bonding to the base material beneath.

Functions of bond breakers The main function of bond bre a k - ers is to minimize dynamic loads d u r ing lifting or stripping of pre c a s t members and permit their com-p l e t e , clean separation from casting slabs or molds. Because chemical c u r ing compounds can interf e r e with or pre vent proper functioning of a bond breaker applied ove r

New generation, chemically active cure and bondbreaker for tilt-up, lift slab and precast construction. (2) Product is packaged in lined steel 5 gal (19 L) pails, 55 gal (208 L) drums and 275 gal (1,047 L) bulk tanks. Drums are equipped with a 2-inch center port opening for use with Nox-Crete's DRUM AGITATOR. (1)

Bond breakers work magic by keeping concrete from sticking to surfaces like forms and molds. Imagine trying to separate two pieces of sticky tape; it’s a hassle. According to the American Concrete Institute, using a bond breaker can reduce formwork stripping time by up to 30%. Less struggle every time you pour means more time for coffee breaks.

Refer to the bond breaker’s TDS for compatible cures or cure & seals. A minimum of two bond breaker applications are required, placed perpendicular to the previous coat. Tilt-up bond breakers are a high liability application that deserves careful and close attention.

A bond breaker is a separator substance applied in between adjoining solid surfaces to ensure that there is no adhesive molecular bond between the surfaces. Bond breakers are commonly used for tilt-up walls and precast segments so that the right pieces are cast together.
