Create test areas for antifouling removal.

Coating thickness and application time should be determined before starting the project by applying several small (approx. 10 cm x 10 cm) test areas. Compare the effect of the undiluted product with that of a product diluted with approx. 10 % water. The product diluted with water often works better on hard antifouling.

YachtStrip

Applying the antifouling remover

Stir YachtStrip Antifouling Remover well before application and then apply evenly to the antifouling with a trowel or spatula. Alternatively, YachtStrip diluted with water can be applied with an airless sprayer. Protect surrounding boats, cars and other surfaces from spray mist! Important: Remove any dust from the surface before applying YachtStrip Antifouling Remover to avoid the formation of a separating layer.

YachtStrip

Mix YachtStrip with water

Dilute YachtStrip Antifouling Paint Remover with approx. 10 % to 15 % water while stirring vigorously. This improves the effect in some cases. Stir in water using a stirrer until the YachtStrip is creamy and a "gyroscopic structure" remains after stirring. It is not always necessary to dilute YachtStrip with water, so it is important to make a decision based on the results of the test areas.

YachtStrip

Cover the paste with foil

Cover the applied YachtStrip promptly with the YachtStrip film to prevent the product from drying out. The film usually adheres to the product even in strong winds. This means that the process can also be used in adverse weather conditions. The film can be used several times. The print should be applied to the side facing away from YachtStrip, i.e. the air side. The print can come off with YachtStrip.

Removing antifouling

Remove YachtStrip and the antifouling coatings as soon as they are well dissolved. Proceeding in sections prevents the YachtStrip antifouling remover and the old antifouling layers to be removed from drying out. First remove the film and then remove the old antifouling layers with a plastic scraper or spatula. Finally, wash with a wet abrasive fleece, a wet sponge or a high-pressure cleaner and allow to dry thoroughly. Alternatively, the residues can be removed by sanding after drying. Collect the removed coatings and dispose of them properly.

YachtStrip

Cleaning the hull

Remove antifouling residues with lukewarm rinsing water and an abrasive fleece immediately after removing the antifouling. Proceed in sections and remove one film at a time. Always clean immediately while the antifouling is still soft and do not allow it to dry again. Once the residue has been removed, simply leave to dry completely and you can start rebuilding. As an alternative to washing off with spray water, you can allow any remaining residue to dry out and remove it by sanding the surfaces, e.g. to protect the primer. Neutralising" is not necessary after removing the coats.

YachtStrip time

Time for antifouling removal

The application time is between 4 and 48 hours, depending on the type and number of antifouling layers. The principle "the longer, the better" should not be applied when using YachtStrip. Coatings above the white line can be removed. If you wait too long, the coating will dry again and it may appear that the coating has not been removed. Factors such as temperature, sunlight, humidity and the type and number of antifouling layers influence the effect of the product. The results of the test area should be applied. If the exposure time is exceeded, 1- and 2-component coatings (including epoxy coatings - see following diagram) may be dissolved. In addition, surface discolouration may occur on wooden boats (this can usually be removed with a brightener).

Time epoxy

Time to remove the epoxy primers

Antifouling coatings can be removed without attacking the epoxy primer if the application time is optimised and applied correctly. Antifouling coatings are removed within 4 to 48 hours, depending on the number, type and age of the coatings. Epoxy coatings generally require approx. 14 hours (with a low antifouling separation layer thickness) to approx. 55 hours (with a high antifouling separation layer thickness). The antifouling forms a separating layer and thus delays the contact between YachtStrip and the epoxy coatings underneath. Remove the antifouling coats as soon as they are well dissolved and then clean the surface with water. Note the results of the test surfaces. Also bear in mind that the antifouling coatings may have different layer thicknesses in different places and the resulting contact time may vary as a result. With "wet on wet" antifouling coatings applied to the epoxy, it is to be expected that the primer may be dissolved in places. In this case, it is recommended to apply another layer of primer before applying the new antifouling.

YachtStrip processing temperature

The recommended ambient temperature during processing should be not below 7°C be. The chemical process slows down at lower temperatures and this shifts the minimum exposure time and the maximum exposure time (see chart on exposure time above). Temperatures above 10 °C and below 26 °C are generally ideal. From approx. 26 °C the active ingredient evaporates so quickly that it can dry out before the antifouling coatings are removed. Please also note that the reaction times depend on the temperature at the time of processing and may therefore differ from the times determined when creating test surfaces. In general, the reaction time of a chemical reaction is approximately halved when the temperature is doubled.

YachtStrip AF remover consumption

The Consumption is approx. 300 g/m² to 1500 g/m² and depends on the number, type and age of the antifouling layers to be removed. As a general rule, you should refrain from Consumption of approx. 100 g/m² to 130 g/m² per layer to be removed to start with. However, if one or two layers of antifouling are to be removed, you should apply at least approx. 300 g/m².

Compared to conventional paint strippers, YachtStrip saves you considerable material, labour and costs. Alternative removers often have to be applied and removed several times due to their shallow penetration. With YachtStrip, on the other hand, you can remove up to 15 layers of antifouling in one application.

Disposing of removed antifouling and YachtStrip

YachtStrip and the removed antifouling coatings must be disposed of as hazardous waste. When stripping, ensure that the removed layers are completely collected. Further information can be obtained at any time from the local water authority.
