Product description
International B-Free Tiecoat is a 2-component primer specially developed for use with B-Free Explore or on top of B-Free Conversion Coat as part of a conversion paint system. International Tiecoat is easy to mix and apply with a brush or paint roller.
The primer is suitable for any boat made of aluminum / zinc-galvanised steel, cast iron, GRP (gelcoat), lead, steel and wood.
Benefits of B-Free Tiecoat
- Promotes strong adhesion for use with B-Free Explore (biocide-free antifouling).
- Easy to apply.
- Apply in one coat for use over International barrier paint systems or the B-Free conversion coat.

The materials, substrates or tasks a product is intended for. A general claim such as 'suitable for plastics' does not mean it works with every type of plastic; the specific substrate and its preparation still matter.
- Polyester boten, Stalen-boten, Aluminium boten, Houten boten
-
The recommended number of coats needed to achieve the intended coverage, thickness or protection. Highly absorbent substrates or different application methods may require additional coats. Allow for the specified time between coats.
- 1 coat
-
The period for which an unopened product remains usable under the specified storage conditions. Check whether the period starts from the manufacturing date or another date. Shelf life may be shorter after opening, especially for products sensitive to air or moisture.
- 12 months
-
The time until the surface no longer feels tacky to a light touch. The material underneath may still be soft, so tack-free does not mean fully cured or ready for heavy loading.
- 2 hours (10 °C)
-
Mixing ratio indicates how much of each component is needed, for example resin (A) and hardener (B). A ratio of 100:50 by weight means 100 grams of A to 50 grams of B; by volume you might use millilitres. Weight and volume ratios are not necessarily the same because the components may have different densities. Accurate measuring is important for proper curing.
- 1:1 (by volume)
-
The overcoating interval tells you when the next layer of paint, varnish or coating may be applied. Many multi-coat systems specify both a minimum and a maximum interval:
- Minimum overcoating time: the previous layer is dry or cured enough to accept another coat.
- Maximum overcoating time: the period during which the next coat can bond without extra surface preparation under the stated conditions.
Overcoating too early can affect drying or the finish. Once the maximum interval has passed, cleaning and sanding may be needed to ensure adhesion between coats. Temperature and film thickness affect the waiting times.
- 5 hours - 5 days (10 °C)
-
Consumption or coverage describes how much product is needed for a given surface area. Consumption may be stated in g/m² or kg/m², while coverage is often given in m²/L or m²/kg. A consumption of 0.2 kg/m² means a theoretical 200 grams per square metre. Actual use depends on film thickness, substrate absorbency, application method and waste.

The application or processing methods specified by the manufacturer, such as brushing, rolling, spraying, casting or hand laminating. The chosen method can affect consumption, layer thickness and finish.

Working time is the period during which a product remains workable after mixing or activation, usually given in minutes at a specified temperature, often 20 °C. With reactive resins, the chemical reaction also continues in the mixing container, and larger quantities or higher temperatures can shorten this time. Working time is different from gel time and full curing time.
- Approximately 180 minutes (at 10 °C)
