FAQs

Can Tikkurila Ultra Primer be used on interior wood?

No, Tikkurila Ultra Primer is specifically formulated for exterior use and is designed to withstand harsh weather conditions. It is not recommended for interior applications.

How long does it take for the primer to dry?

The primer is touch dry in approximately 1 hour and recoatable in 2-4 hours, depending on temperature and humidity conditions.

Can I use this primer with any exterior paint?

While it provides an excellent base for all Tikkurila exterior wood paints, it is ideally designed for use with Tikkurila Valtti Opaque and other compatible Tikkurila exterior systems for maximum durability and performance.

Is Tikkurila Ultra Primer suitable for pre-treated or stained wood?

Yes, it is suitable for previously coated exterior wood surfaces in good condition. Ensure the surface is sound, clean, and lightly abraded for adhesion.

How do I clean my tools after using this primer?

Clean application tools, brushes, rollers, and spray equipment with water immediately after use. Dried primer can be more difficult to remove.

Can I tint the Tikkurila Ultra Primer?

Yes, Tikkurila Ultra Primer can be tinted towards your chosen topcoat colour. This helps enhance opacity and supports even colour development.

What is the main benefit of using a primer like Ultra Primer?

The main benefit is creating a sound, protective foundation for your topcoat. It enhances adhesion, blocks stains like tannins, prevents moisture ingress, and contributes to the overall longevity and appearance of the exterior wood finish.

Troubleshooting

Primer not adhering well to the surface.

Ensure the surface was properly prepared. It must be clean, dry, free from dust, grease, and loose paint or coatings. Lightly sand previously painted surfaces for better grip.

Tannin or resin bleed-through observed.

Ensure adequate primer coverage and allow sufficient drying time before applying the topcoat. A second coat of primer may be necessary on woods prone to heavy bleed-through.

Uneven finish or poor topcoat coverage.

Apply the primer evenly. If the primer is tinted, ensure it was mixed thoroughly. Apply topcoats according to manufacturer recommendations, ensuring proper application techniques.

Primer appears chalky or powdery after drying.

This can occur if applied too thinly or in very humid conditions. Ensure even application. Lightly sand if necessary before recoating.

Primer remains wet for an extended period.

Check temperature and humidity. Application below 5°C or above 80% humidity can significantly slow drying. Ensure good ventilation and avoid application in poor conditions.

Setup, Compatibility & Care

Surface Preparation: For optimal performance, all exterior wood surfaces must be clean, dry, and free from dust, grease, and loose material. New timber should be planed or sanded. Previously painted or treated surfaces should be lightly sanded to ensure adhesion. Remove any mould or algae with a suitable cleaner. Ensure timber moisture content is below 20%.

Application: Apply Tikkurila Ultra Primer using a high-quality brush, roller, or spray. For best results, apply a generous, even coat. Avoid over-thinning. Ensure adequate ventilation during application and drying.

Drying Times: Touch dry in approximately 1 hour at 20°C and 50% relative humidity. Recoatable in 2-4 hours. Application should not be carried out if the temperature is below +5°C or if the relative humidity is above 80%.

Compatibility: Ultra Primer is designed as an ideal basecoat for Tikkurila exterior wood paints, such as Valtti Opaque. It is suitable for new or previously treated exterior wood including cladding, weatherboards, doors, windows, fascias, soffits, fences, and railings.

Care: After application and drying, the primed surface should be kept clean. Regular inspection of the painted surface and prompt cleaning of any dirt or debris will help maintain the integrity of the finish. Clean tools and equipment with water immediately after use.
