K Rend HP12 Basecoat Render 25kg

This basecoat is a scratch coat or stipple coat for use on dense or difficult substrates, providing improved adhesion & water resistance before the topcoat is applied.

High Polymer technology enhances the bonding strength, flexibility and water resistance of the render, making it more durable & effective on challenging backgrounds.

Each bag weighs 25kg, which is standard for render products of this type.

The basecoat has a quick mixing time of around 5 minutes.

The render is typically applied by hand or machine onto the substrate as a base layer. It's then scratched or stippled to provide a key for the next coat.

HP12 is suitable for a wide range of dense and low-porosity backgrounds where traditional renders may not adhere as effectively.

Yes, K Rend HP12 has properties that can aid thermal performance. It's a good choice for modern external wall insulation systems.

One of the render's main benefits is enhanced water resistance, helping protect buildings from moisture ingress.

Yes, HP12 is commonly used as a base layer in the K Rend system, designed to work seamlessly with their finishing coats.

To mix the render, add the powder to clean water & mix thoroughly using a mechanical whisk or render mixer until a smooth consistency is achieved.

Depending on the substrate, a stipple coat or primer may be required before applying HP12 to ensure maximum adhesion, particularly on very smooth or dense surfaces.

Polymer renders like HP12 provide better adhesion, flexibility, water resistance & ease of application, reducing the risk of cracking and detachment.

HP12 is specifically designed for external rendering projects, offering durability and weather protection.

A hawk and trowel are recommended manual application or a render spray machine can be used for larger projects, depending on the job size.

Store unused bags of render in a cool, dry place that is off the ground & protected from moisture. Once opened, use promptly to prevent the material from absorbing water.
