Weld-Crete® Concrete Bonding Agent
Weld-Crete® bonds new concrete, stucco, tile setting beds and terrazzo to any structurally sound surface, interior or exterior. Use Weld-Crete’s® open time to your advantage in bonding to concrete shear walls when you need a time lapse between application of bonding agent, placement of reinforcement steel, placement of formwork and placement of concrete. The original chemical concrete bonding agent incorporates polyvinyl acetate homopolymer in a patented formulation.

- For exterior and interior use.
- Will bond new concrete, Portland cement plaster and cementitious mixes to structurally sound concrete floors, walls, columns, beams, steps and ramps.
- Can be “painted on” in a single application 1 hour to 10 days prior to concrete placement.
- Weld-Crete® is also used for: bonding setting beds for ceramic tile; bonding Portland cement plaster and stucco mixes; and to bond to surfaces such as brick, block, tile, marble, metal, glass block, soundly adhered paint (non-soluable in water, i.e. casien and calcimine paints), and silicone.

Plaster-Weld
Plaster-Weld® bonds new plaster to any clean, structurally sound, interior surface. The original chemical plaster bonding agent is a patented formulation incorporating polyvinyl acetate homopolymer. DESIGNED FOR INTERIOR USE ONLY, the 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.

ADMIXTURE Cement Bonding Agents
MasterEmaco A 660 (formerly Acryl 60)
Acrylic, polymer emulsion additive for cement-based powders designed to improve adhesion, tensile, compressive, and flexural strengths. Non-yellowing, water-based ideal for both interior and exterior use.
- Promotes long-lasting repairs.
- Adds extra toughness and crack-resistance to cement-based mixes.
- Use for interiors or exteriors; above or below-ground.
- Improves freeze/thaw stability of cement-based materials.
- Ideal where hard, strong, fast-curing material is required for patching, repairing or resurfacing.
- Milky white, colorless and non-yellowing to mixture.
- Stable, will not re-emulsify when exposed to water.
- Easy to use. One-component liquid mixes easily with water.
- Cleans up with soap and water immediately after use.
Recommended for:
- Cement
- Mortars
- Plasters
- Stuccos
- Concrete Mixes
- Most Cement-based Materials
Add to THOROSEAL®, THORITE® and THOROSEAL® Foundation Coating for:
- Stronger bonding capability and increased tensile strengths.
- Complete protection against water, dampness or seepage.
Coverage:
- Can be used straight, or be diluted with water 1:3. Coverage will vary depending on application and use.
- Coverage depends on the suggested mixing ratio for particular uses.

SikaLatex R Bonding Agent
Acrylic latex bonding agent/admixture for portland-cement mortar/concrete
SikaLatex® R is an acrylic-polymer latex. It is not re-emulsifiable. It is a general purpose admixture which will produce polymer-modified concrete and mortar. Sika Latex R is also a bonding grout when mixed with sand and portland cement.
Advantages:
- Concrete/Mortar/Grout/etc. containing SikaLatex® R exhibits improved adhesion to pre-pared substrates
- Increased adhesive strength of mortar/concrete when used as a bonding grout
- Increased resistance to freeze/thaw durability
- Does not produce a vapor barrier
Use:
- As a liquid admixture in cement mortars and concrete to enhance adhesion and overall performance.
- For sand and cement bonding grouts.
- With stucco and terrazzo.
- For patching and flash coats.
- As a polymer admixture added to SikaRepair® mortars to further improve their performance.
