Mask or otherwise protect windows, trims and adjacent wall, roof and floor areas against spills and splashes using tape, plastic film or similar.

Before applying Euromix™ Patch Coarse check that the substrate has been constructed in accordance with the relevant manufacturer’s instructions and that it is completely dry and free of any damaged, loose or friable material. Remove any coatings that may affect adhesion of the Patch, like; paint, grease, oil or mould release agents.

Exposed fibre-cement and other similarly porous substrates should be primed before the application of any Patch.

The Patch Coarse should be thoroughly stirred in the bucket, using a power stirrer, prior to application.

In situations where a quicker setting time or a harder surface finish is required Portland cement can be added to the Patch Coarse at the ratio of 5-10%, by volume (75 – 150 grams of cement per litre of Patch Coarse). This should be done in a separate bucket, mixing only enough material that can be reasonably applied within 2 hours.

Do not apply Euromix™ Patch Coarse in wet conditions, when rain is imminent or in temperatures outside the range of 10C to 35C. Do not apply if rain or frost is imminent and protect from rain during the product’s curing period.

Applying Euromix Patch Coarse as a Render Coat

Trowel the Patch Coarse on to the surface of the substrate, to approximately 2mm thickness and then flatten with a plastic finishing trowel applied in a circular motion, to achieve an even texture. It is imperative that a 'wet-edge' is maintained while applying the Patch. It is also important to ensure that the material is not over worked as this will likely result in a patchy finish.

Once fully cured (minimum of 24 hours in ‘normal’ weather), Euromix™ Patch Coarse can be top coated with any of the Euromix® Acrylic Renders, Paints or Textures.


Coverage rates will vary depending on the substrate and the thickness applied, but as an approximate guide 15 Litres of Euromix® Patch Coarse should cover about 12 to 15 SQM (when applied at a thickness of about 2mm)

Drying and Curing

Drying and curing of the product is affected by type, dryness and porosity of the surface, temperature, humidity, ventilation, climate conditions and application technique and therefore drying and curing can only be given as a guide (at 25C & 50% RH):

Touch Dry

Thirty (30) - sixty (60) minutes, depending on thickness.


Twenty four (24) hours
