FAQs

How long does Smartseal Smooth Wall Coating typically last?

The coating is designed to last for up to 15 years when applied correctly to a suitable substrate.

Can I use this paint on interior walls?

Yes, the solvent-free, breathable formulation makes it suitable for both internal and external masonry walls.

What is the drying time for this product?

The paint should be touch-dry within a few hours, but it takes approximately 24-48 hours to fully cure.

How do I clean the painted surface?

The surface can be easily cleaned using water and a soft brush or cloth. Avoid abrasive cleaners.

Is this product suitable for covering existing cracks?

Yes, the coating has excellent crack-bridging properties and can fill and cover small hairline cracks during application.

What preparation is needed before applying the coating?

All surfaces must be clean, dry, and free from loose material. Remove dust, dirt, algae, and any flaking paint. Priming may be necessary for chalky or very porous surfaces.

Does the 'breathable' feature mean it's not waterproof?

No, it is waterproof to prevent external water ingress. The breathability refers to allowing internal moisture vapor to escape, preventing damp build-up.

Can I apply this with a spray gun?

Yes, it is suitable for application by brush, roller, or airless paint sprayer for a perfect finish.

Troubleshooting

Paint not adhering properly or peeling

Surface was not adequately prepared. Ensure the substrate is clean, dry, and free from dust, grease, or loose material. Re-prepare the surface and reapply.

Uneven finish or brush marks visible

Application technique may be incorrect. Ensure paint is applied evenly with consistent strokes. Use a high-quality brush or roller. For sprayer application, maintain consistent pressure and distance.

Water ingress or damp patches appearing

Coating may not have fully cured or may be insufficient. Ensure adequate drying time has passed. Check if the applied thickness is sufficient and if there are any missed areas or breaches in the coating. Apply additional coats if necessary.

Cracking appearing after application

The coating may not have been applied to a sufficient thickness or may be bridged over existing structural cracks. Ensure the coating is applied to the recommended thickness. For significant structural cracks, these should be repaired before coating application.

  • Environmentally friendly, solvent-free, and low-odour.

Cons

Setup, Compatibility & Care

Preparation: Ensure all surfaces are clean, dry, and free from loose render, dust, and algae. Remove any existing flaking paint. For best results, apply a suitable primer if necessary, especially on chalky or porous surfaces. Test compatibility on a small, inconspicuous area first.

Compatibility: Suitable for most types of external and internal masonry, including brickwork, stone, concrete, and rendered walls. Not recommended for use on flexible coatings or surfaces that are subject to constant high-pressure water immersion.

Application: Apply evenly using a brush, roller, or airless paint sprayer. Two coats are generally recommended for full coverage and optimal performance. Allow 24-48 hours for the coating to fully cure before exposing it to heavy rain or washing.

Care: Clean with water and a soft brush or cloth. Avoid abrasive cleaners or high-pressure washing, which can damage the coating.
