Product characteristics

Controlled performance
for the right surface.

Used with a suitable primer system, it helps fill voids, improve surface evenness and achieve a more uniform topcoat application.

Areas of use

Filling and levelling concrete, aerated concrete, render and similar mineral exterior surfaces.

A complete system approach

Surface preparation, a compatible primer, the appropriate coating build and controlled environmental conditions are considered together.

Product selection guide

Exterior Wall Filler: three decisions to make

01
Define the service requirements

Select a filler to improve surface evenness. Consider interior/exterior suitability, defect size and the subsequent primer/paint system together. Deep structural repair is different from fine surface levelling.

02
Prepare the substrate and process

Remove loose or powdery layers, complete repairs and allow them to dry. Address the source of moisture or staining instead of merely covering it. A test area helps confirm colour and texture.

03
Confirm the system limitations

Filler alone does not resolve moving cracks, water ingress or unsound render. Do not transfer the use conditions of an exterior filler to an interior filler or vice versa.

Frequently asked questions

Exterior Wall Filler: detailed guidance

Five key topics for purchasing and application planning. Pack sizes follow the business packaging schedule; technical values must be checked against current documentation for the supplied product.

Where should Nanomix Exterior Wall Filler be considered, and how should the substrate be assessed?

Exterior Wall Filler is a surface-levelling product developed to correct imperfections before painting and provide a more uniform foundation for the topcoat. Listed applications: Filling and levelling concrete, aerated concrete, render and similar mineral exterior surfaces.

Select a filler to improve surface evenness. Consider interior/exterior suitability, defect size and the subsequent primer/paint system together. Deep structural repair is different from fine surface levelling. Remove loose or powdery layers, complete repairs and allow them to dry. Address the source of moisture or staining instead of merely covering it. A test area helps confirm colour and texture.

Before specifying the product, provide the technical team with the substrate, existing finish, service exposure and intended application method. A representative trial helps establish adhesion and appearance; it does not replace the required system approval for demanding exposure. Filler alone does not resolve moving cracks, water ingress or unsound render. Do not transfer the use conditions of an exterior filler to an interior filler or vice versa.

How should Nanomix Exterior Wall Filler be prepared, mixed or diluted?

The product record lists: Acrylic copolymer emulsion. Preparation information: Ready to use; do not thin.

Do not add water or solvent to a ready-to-use filler unless the approved instructions require it. Work in controlled layers with a suitable trowel or spatula rather than attempting excessive thickness in one application.

Measure any permitted water addition rather than judging consistency by eye. Keep dilution consistent across adjacent areas and record differences between first- and second-coat instructions. Ready-to-use fillers or decorative materials must not be diluted simply because a related wall paint allows it. Prepare a sample to check texture, hiding and tool marks before treating the full surface.

Which pack sizes are available for Nanomix Exterior Wall Filler, and how should quantities be planned?

The quotation packaging preferences are: 3 kg pail; 25 kg pail. Confirm the selected pack, colour and availability at quotation stage. Kilograms describe net mass and litres describe net volume; conversion requires the density of the supplied product.

The product record lists: theoretical coverage — Dependent on substrate and application method; refer to the current technical data sheet. This is not a guaranteed site yield. Check whether the value refers to one coat, a specified film thickness, the mixed kit or the base component. Account for substrate texture, absorbency, application losses and the required number of coats.

Measure the actual area, include the specified coat sequence and use a representative trial to refine the purchase quantity. Match colour and batch information for adjoining surfaces. Keep unused material in its original labelled packaging and follow the product storage instructions; pack size does not establish shelf life or storage temperature limits.

When can Nanomix Exterior Wall Filler be recoated or put into service?

The product record lists: drying information — Dependent on conditions, substrate and film thickness; refer to the current technical data sheet. Confirm the reference temperature, film thickness and test conditions before using these values in a production schedule.

Do not start sanding or painting merely because the surface skin is dry. Layer thickness and ambient conditions affect drying through the body of the filler; follow product-specific conditions for the next operation.

Measure site conditions rather than relying only on the weather forecast. Substrate temperature, moisture, ventilation and the actual applied thickness can change the result. Obtain product-specific application limits and recoat instructions before work begins; do not copy temperature limits from a different resin family. Consult the safety data sheet for ventilation and handling requirements.

How should related products and the technical documents for Nanomix Exterior Wall Filler be used?

Assess the complete sequence, including preparation, any primer or intermediate coat, the specified product and associated auxiliary materials. The related links on this page are options for technical assessment; a shared brand or resin-family name is not proof of compatibility.

The linked archive includes an entry for this product. It is a reference for planning, not a replacement for the current batch-specific technical data sheet. The download identifies the original catalogue page numbers. No publication date or revision is specified in the supplied source, so the website review date must not be read as a manufacturer document issue date.

Request the current technical and safety data sheets using the product code and intended application. Resolve any missing mixing ratio, recoat interval, exposure limitation or document discrepancy before use. The application guide supports planning and inspection; it does not establish a certified resistance class or replace a project-specific coating specification.

Application control

Reliable results begin
with a controlled process.

Apply with a spatula or flexible steel trowel to a sound, clean and dry surface. Regulate absorbency on porous substrates using a suitable Nanomix primer.
