Pour the mixed product onto the floor and spread evenly with a steel trowel to form a thin, tight scrape coat. Immediately add further quantities of mixed product to leave a smooth finish (if not, trowel again when the surface is still damp but firm to the touch). If required use a spiked roller to provide a more uniform surface appearance. Additional layers, each not exceeding 6 mm, may be applied to achieve the required depth for your project. Prime with SikaBond® PVA+ diluted 1:3 with water between layers.

If applying the mortar with a brush take care to evenly cover the entire surface. The maximum recommended layer thickness is 1 mm per layer. The application of a minimum of 2 or 3 coats is recommended (subsequent coats must be applied cross-wise and you must until the first coat is dry to apply the next coats).
If applying with a trowel the application must be done covering the whole surface of the substrate with uniform thickness. Press the trowel firmly against the surface. At least 2 coats must be applied with a final thickness of at least 3 mm. The maximum recommended thickness for each layer is 2 mm.
Refer to the Product Data Sheet for detailed application instructions.

You must dampen the substrate before applying the first coat to ensure adhesion. Apply the first layer to approximately 0.5 mm thickness. Allow at least 2 hours of curing before applying a second coat. Slightly dampen the first coat, removing any excess moisture, and apply the second coat perpendicular to the previous coat. The second layer should be approximately 1.5 mm thick to ensure a total membrane thickness of 2 mm.
