Maxcrete 201 Bonding Agent: Product Information and Application Guidelines

Product Overview

Description: Maxcrete 201 is a modified Styrene Butadiene emulsion designed for enhancing bonding properties in cement mortars. It serves to intensify cement-sand mixes, improving resistance and strength.

Features:

Greatly increases adhesion strength
Excellent water resistance, reducing efflorescence
Enhances mortar flexibility, reducing shrinkage and crack formation
Improves chemical and abrasion resistance
Enhances compressive strength
Non-toxic

Uses:

Bond coat and primer for topping
Increases impermeability and chemical resistance
Keying coat over smooth surfaces to apply renders
Increases bonding strength of cement and dry mix to set tiles, slates, and natural stones
Used in creating high-strength repair grouts

Preparation

Concrete surfaces must be clean, sound, and free from contaminants, laitance, and loose particles.
Absorbent substrates must be saturated thoroughly, leaving no standing water before application.

Application Guidelines

Bonding Slurry:
- Mix to a creamy consistency and brush into the surface to obtain a 1mm thick coat.
- Apply topping while the slurry is still wet.
- Coverage: Approximately 0.6 liter/m² @ 1mm thick
Splatter Key:
- Mix to a creamy consistency and trowel a thin layer onto the smooth concrete surface.
- With a stiff brush, dab more material onto the skim layer to create rough keys.
- Coverage: Approximately 0.3 liter/m² depending on key density
Screed & Plaster:
- Premix Maxcrete 201 to water and Cement to Sand before mixing wet and dry components.
- Mix to the desired consistency. Wall renders shall not exceed 10mm per layer.
- Scratch the render and allow it to dry for 6 hours before applying the next coat.
- Coverage: Approximately 1 liter/m²/cm @ 1:1 dilution
Tile Adhesive:
- Premix Maxcrete 201 to water and Cement to Sand before mixing wet and dry components.
- Mix until a creamy consistency is achieved.
- Spread a thin uniform layer onto the substrate and apply additional mortar with a notch trowel.
- Back butter ribbed backed or large format tiles before placing with firm pressure.
- Coverage: Approximately 0.4 liter/m² @ 1:1 dilution, using a 6 x 6mm notch trowel
