Product Information

Full details

Its key benefit is providing a smooth, sandable surface that seals wood and prevents dyes from bleeding. A potential caveat is its alcohol-based nature, requiring good ventilation.

FAQs

What is the coverage rate of the 4 Litre Shellac Sanding Sealer?

The coverage rate is approximately 13-15 square meters per litre.

Can I use this sealer on MDF or particle board?

Yes, it can be used on composite wood materials like MDF and particle board to seal them effectively.

How long does the sealer take to dry?

Drying time can vary depending on conditions, but it typically dries to touch within 15-30 minutes and is ready for sanding in 1-2 hours.

What solvent should I use for cleaning brushes?

Brushes and equipment should be cleaned immediately after use with methylated spirits.

Is this product suitable for outdoor use?

This sealer is primarily designed for interior wood finishing. For outdoor applications, a more durable, weather-resistant finish would be recommended.

Can I apply a water-based varnish over this sealer?

It is best to test compatibility on a small, inconspicuous area first, as water-based finishes can sometimes react with alcohol-based sealers.

Troubleshooting

Sealer is too thick and difficult to apply.

Ensure the product has not been stored for too long. If necessary, a small amount of additional methylated spirits can be added to thin it slightly, but use sparingly.

Sanding is clogging the sandpaper.

Ensure the sealer is completely dry before sanding. If it's still soft, additional drying time is needed. Apply thinner coats for better drying.

Dye is still bleeding through after sealing.

A second coat of sealer may be required. Ensure the first coat was applied evenly and allowed to dry fully before applying the second.

Setup, Compatibility & Care

Setup: Ensure the wood surface is clean, dry, and free from dust, grease, and old finishes. Stir the sealer thoroughly before use. Apply thin, even coats using a brush.
