LARSEN CONCRETE & PLASTER BONDING AGENTS

Wherever You Need High Performance Bonding Of Cementitious Material Direct To Structural Surfaces

Concrete & Plaster Bonding Systems Worldwide Since 1952

COMPOSITION & USES

WELD-CRETE®

The original chemical concrete bonding agent incorporates polyvinyl acetate homopolymer in a patented formulation. For exterior and interior use, Weld-Crete® will bond new concrete, portland cement plaster, and cementitious mixes to structurally sound concrete floors, walls, columns, beams, steps and ramps.

It can be "painted on" in a single application 1 to 10 days prior to concrete placement.

Use Weld-Crete's open time to your advantage in bonding to concrete shear walls, where you need a time lapse between application of bonding agent, placement of reinforcing steel, placement of formwork and placement of concrete.

Weld-Crete® is also used for bonding setting beds for ceramic tile and for bonding portland cement plaster and stucco mixes; and to bond to such surfaces as brick, block, tile, marble, metal, glass block, soundly adhered paint (non-soluble in water), and silicone.

PLASTER-WELD®

The original plaster bonding agent is a patented formulation incorporating polyvinyl acetate homopolymer.

DESIGNED FOR INTERIOR USE ONLY. High performance bonding of one-coat finish plaster and/or two and three coat work to concrete ceilings, walls, columns, beams, and other structurally sound surfaces. Plaster-Weld® prepares the surface to allow you to plaster directly to concrete over electric radiant heat cable, and to bond cement mortar beds to smooth concrete for installation of rigid foam insulation. Concrete, brick, block, glass, ceramic tile, wallboard, metals (e.g. sheet lead in x-ray rooms) and marble are suitable sound surfaces, structurally. Plaster-Weld® can be used over paints having oil, rubber or vinyl bases, and over silicone-treated surfaces, as well as latex paints.

ACRYLIC ADMIX 101

Acrylic Admix 101 is an integrally added bonding agent to bond new concrete, portland cement plaster, and mortar mixes, interior or exterior. It is an organic polymer (a white, milky liquid) which is mixed with varying proportions of water according to the performance required for the modified portland cement mix, i.e., tensile bond strength, etc. This ratio usually ranges from one part acrylic to one to three parts water.

It also creates a hard, durable surface resistant to most chemicals and acids, imparts excellent water and weather resistance, improves curing qualities and reduces shrinkage cracking. Bonded assemblies are unaffected by water.

INTERSPAN®

A New, Unitized Epoxy Based Expansion Joint System Designed For Concrete Decks, Platforms, Parking Ramps, Walkways And Many Other Structures.
