Nubian primerplast 750 ml – code: .117 – Euromeci

Primer for new gel-coat: adhesion base for antifouling cycles

Nubian Primerplast 750 ml (code .117, Euromeci) is a primer designed for the preparation of new gel-coat before applying antifouling paints. In the nautical field, proper substrate preparation is a crucial step to achieve a neat and consistent painting cycle: this product was created precisely to promote the adhesion of the antifouling on surfaces that, during construction, may have residues of release agents and silicones.

The primer is also suitable on two-component primers and on some epoxy primers commonly used in maintenance, such as RESINA 90 anti-osmosis, RESINA 99 and FONDO 22, when you want to prepare a suitable substrate for the subsequent antifouling finish.

Product features and details

Why use a primer on new gel-coat

Freshly applied gel-coat can be “difficult” to paint directly: during construction, materials that facilitate release from molds may be used and, if not removed, can interfere with the adhesion of subsequent products. Nubian Primerplast is formulated to be used as preparation layer before the antifouling, helping to create a base more suitable for the cycle.

Recommended substrates (based on available information)

• New gel-coat, properly prepared.
• Two-component primers.
• Epoxy primers such as RESINA 90 anti-osmosis, RESINA 99 and FONDO 22.

Format and identification

• Format: 750 ml
• Product code: .117
• SKU: EUR0000017

Typical applications in boat maintenance

Nubian Primerplast is used in hull maintenance work and in the preparation phases before applying the antifouling. It is particularly useful when:

• antifouling needs to be applied on new gel-coat;
• working on surfaces that have already received a two-component primer and you want to properly prepare the finish;
• using epoxy primers such as RESINA 90, RESINA 99 o FONDO 22 and you want to improve the adhesion of the antifouling to the cycle.

This primer is a consistent choice for those who want to follow an orderly procedure: substrate preparation → primer → antifouling, reducing the risk of “direct” applications on surfaces that are not properly prepared.

Operational advantages

• Improves adhesion of antifouling paints on new gel-coat, where preparation is fundamental.
• Supports cycles on two-component primers and on indicated epoxy primers, helping to manage maintenance and restoration work.
• Simple application with a brush, with clear operational instructions to achieve a thin and even coat.
• Conservative approach to the cycle: useful when you prefer to insert a preparation layer between primer/gel-coat and antifouling.

Usage and application notes

Surface preparation

To achieve a consistent result, the surface must be properly degreased and sanded with fine sandpaper. This step serves to remove residues of release agents and silicones used on site during construction. Careful preparation is particularly important on the new gel-coat, where any contamination can compromise the adhesion of subsequent layers.

Mixing and application

• Stir well the product before use.
• Apply with a brush avoiding crossing brushstrokes.
• Spread one-handed use not abundantly, so as to obtain a thin and uniform layer.

Overcoating

The’antifouling can be applied after 4-5 hours.

Practical note

To keep the cycle clean and repeatable, it is advisable to organize the work phases (preparation, primer, finishing) so as to respect the indicated times and apply the product on properly prepared substrates. If the substrate or the existing cycle presents particular conditions, evaluate the most suitable procedure before application.

FAQ – Frequently Asked Questions

What is Nubian Primerplast used for on new gel-coat?

It helps improve the adhesion of antifouling paints on new gel-coat, after proper surface preparation (degreasing and fine sanding).

On which substrates can it be applied besides gel-coat?

It is also suitable on two-component primers and on epoxy primers such as RESINA 90 anti-osmosis, RESINA 99, and FONDO 22, as a base before the antifouling paint.

How many coats of primer should I apply?

The instructions indicate to apply only one thin, uniform coat, not too heavy.

How is it correctly applied with a brush?

Stir well and apply with a brush without crossing the brush strokes, spreading a thin coat on a degreased and finely sanded surface.

How long after can I apply the antifouling paint?

The antifouling paint can be applied 4-5 hours after applying the primer.
