What is lacquer blushing?

Blushing (or velado) is an opaque, whitish effect that appears in the lacquer film, generally caused by trapped environmental humidity during drying or due to incorrect application. In most cases, the appearance of this “clouding” is caused by applying lacquer in areas with high humidity and/or excessive heat.

This spray works by reopening the surface structure of the lacquer to release that moisture, restoring the original transparency without compromising the integrity or adhesion of the finish.

Instructions for use:

• Versatility: Can be used during the lacquering process (wet-on-wet) or once the lacquer has surface-dried.

• Preparation: Shake the container well for 20–30 seconds.

• Application: Spray evenly at a distance of 15–25 cm over the affected area.

• Result: You will see the blushing disappear as the lacquer levels out. Allow to dry completely.

Tip: If the blushing has not been completely eliminated after the first coat, repeat the process until the objective is met.

Technical note: No rubbing is necessary. The product evaporates without leaving residue. If you wish to level the gloss with the rest of the piece after total drying, you can perform a gentle buffing with a microfibre cloth.

Frequently Asked Questions (FAQ)

Is it suitable for polyurethane and nitrocellulose lacquers? Yes. The spray is safe and effective on most solvent-based varnishes and lacquers, including two-component polyurethane and lutherie-grade nitrocellulose.

Can it be used on untreated wood? No. This product is designed exclusively to act on finishes (varnish or lacquer). Its use on raw wood will have no effect and could stain the pores.

Is it easy to apply? Completely. It is a “one-step” solution. It only requires spraying over the opaque area and letting the product’s chemistry do its work. It leaves no marks or solvent residues.

Does it remove deep water marks? It is ideal for environmental blushing (humidity). For water stains that have penetrated deep into the wood or cup rings (white heat marks), it may help to attenuate them, but its primary function is correction during the lacquering process.

How long does it take to dry? It is a fast process. Depending on the temperature and ventilation, the surface will be stabilised within a few minutes.
