Removing Antifouling with YachtStrip

Test patch

YachtStripAuftragen The thickness of paste and the duration of exposure should be clarified with the help of a small (10cm X 10cm) test patch before you start your project. Compare the impact of the pure YachtStrip with the result when 10% water are (is) added to the product. The version containing water frequently works better on hard antifoulings.



YachtStrip can be applied with a float or a spatula. Stir well before use in order to increase the spreadability of the product. Determine the necessary thickness by applying a test patch before starting your project. You may mix YachtStrip with up to 15% water before application. However we strongly advise to compare the results of both versions beforehand in order to achieve the best result. For application with an airless system it is absolutely necessary to mix the product with water.



Mixing with water


Dilute YachtStrip with 10% to 15% of water and stir heavily. In some cases this procedure will make the paste much more effective. Stir the water with the help of a mixer until the paste is creamy and shows a circular Structure.





YachtStripFolieWork in sections and cover applied areas with the YachtStrip foil as soon as possible in order to reduce the rate of evaporation. The blanket adheres well to the paste and can in most cases withstand stronger winds if the edges are in contact with the paste. The foil can be reused as cover or used to catch the removed antifouling.



Dwell time


The dwell time depends on the amount of layers of antifouling that have to be removed. Usually it takes 4 to 48 hours. The rule “The longer, the better” should not be applied when using YachtStrip. The coating can be removed above the white line. If you wait too long the antifouling will harden again. Factors like temperature, insolation, humidity and amount of the layers of antifouling are influencing the impact of the product. The results of the test area should be applied. It is possible that 1 and 2 component coatings including epoxy could be dissolved when exceeding the dwell time for antifouling removal. (see as well graphic below). Furthermore the surface of wooden boats could darken, but this could be reversed using a lighting agent.




Antifouling coating can be removed without dissolving the Epoxy coating when YachtStrip is applied correctly and the dwell time is perfect. Depending on type, thickness and age of the layers the antifouling can be removed within 4 to 48 hours. In general epoxy coatings will need between 14 hours to 55 hours depending on the amount of antifouling paint separating the YachtStrip from the primer and subsequently delaying the reaction with the primer. Remove the antifouling once the coating is dissolve and clean the surface with water afterwards. Consider the results of the test patch and keep in mind that the thickness of the antifouling can fluctuate across the area and the dwell time subsequently varies. If the antifouling has been applied wet on wet onto the primer there is an increased potential for the primer to be dissolved sporadically. In this case it is advisable to apply new layers of Epoxy primer prior to the new antifouling paint.



YachtStripEntfernenRemove the product as soon as the antifouling paint is dissolved and wash down with some soapy water and a scoch pad. Remove the foil one by one in order to avoid drying out. Don't forget that the removes antifouling paint is usually highly toxic and dispose of the waste accordingly.

In some surroundings it is possible to finish of by washing the hull with a jet-wash.


The YachtStrip Scraper


The YachtStrip scraper is perfect for removing the dissolved antifouling.  It has a flexible but sharp edge which reduces the risk of damaging the hull compared to a metal spatula.





The necessary coverage is between 300g/m² to 1500g/m² and depends on the type, thickness and age of the antifouling paint. In general a coverage of 100g/m² to 130g/m² per antifouling layer should be assumed. When removing one or two layers of antifouling a minimum of 300g/m² should be used. Compared to other strippers YachtStrip penetrates coatings deeper subsequently removing up to 15 layers of antifouling in one application. This saves time and money.



The recommended ambient temperature should not be below 7 °C during the duration of the application of Yachtstrip. The chemical process slows down at low temperatures resulting in an undefinable delay of the minimum and maximum dwell time. In general better results can be expected at temperatures above 10 °C.




YachtStrip and the removed antifouling coatings have to be disposed as special waste due to the toxic particles in the antifouling coating. Ensure that all the removed materials are collected. Further information regarding rules and regulations should be obtained from your local authority.
