Application tips

To achieve the best result with this varnish, consider the following points:

1. Shake the can well for at least one minute before use, to ensure the product is properly homogenised.
2. Apply in thin, crossed layers, keeping the can about 25-30 cm from the piece. It is preferable to apply two or three light coats rather than a single thick layer, which could cause runs or a milky effect.
3. Work in a well-ventilated environment and at room temperature, avoiding conditions of high humidity or extreme cold, which can affect drying and the final finish.
4. Allow to dry completely between layers before applying the next one. On resin, ensure the surface is clean and free of release agent.
5. Once finished, turn the can upside down and spray for a few seconds to clean the valve and prolong the life of the spray.

Why a matte varnish?

The matte finish is preferred in modelling when seeking realism and visual discretion. It eliminates unwanted gloss that can highlight paint layers or transitions between areas, and is especially useful in figures, dioramas and bodies with complex paint schemes. It also facilitates the subsequent application of weathering effects, washes or filters with brands like Vallejo, Tamiya or Ammo, as the matte surface retains these products better.

Frequently asked questions

Is it compatible with acrylics and enamels?

Generally, spray varnishes are compatible with acrylic paints once they are fully cured. With enamels, it is advisable to ensure that the base coat is well dried before applying the varnish to avoid reactions. If in doubt, always perform a test on a sacrificial piece.

Can I use it on decals?

Yes. In fact, one of the most common applications of matte varnishes is to seal and protect decals once applied and dried, visually integrating them with the rest of the body or model.

How many coats are recommended?

Two thin and well-applied coats are usually sufficient to achieve adequate protection and a homogeneous matte finish. A third coat can be added if greater protection is sought for parts subjected to more handling.

Does it alter the colour or finish of the base paint?

Being transparent, it does not alter the underlying colour. It may slightly reduce the gloss of satin or semi-gloss finishes, providing that uniform matte tone which is precisely its function.

Is it suitable for 3D printed resin parts?

It can be used on resin parts, provided they are properly cured, sanded and clean. Ensure that no release agent or curing inhibitors remain on the surface before applying the varnish.
