Product Benefits

1-component formulation

Sikaflex 291i is a one-component formulation that has been specifically developed to provide superior bonding and sealing properties in marine applications. This product is ideal for use on boats, yachts, and other watercraft as it can withstand harsh environments such as saltwater, UV rays and extreme temperatures. The one-component formula means that there is no need to mix different components together before application, making it easy to use.

Highly elastic

One of the standout features of Sikaflex 291i is its highly elastic properties. This means that it can stretch and compress to accommodate any movement or strain on the material it is applied to without cracking, splitting or losing its bond. This kind of elasticity makes Sikaflex 291i ideal for use in areas where there are vibrations, temperature fluctuations or dynamic loads.

Low odour

This feature makes Sikaflex 291 an ideal adhesive and sealant for use in confined spaces where strong fumes can cause discomfort or even health issues. The low-odour formula also means that it can be used indoors without causing any unpleasant smells.


Sikaflex 291i’s unique formulation ensures that it does not corrode metals, making it a great option for sealing joints and seams in boats and other watercraft. This product can be used to bond and seal a range of materials, including wood, metal, plastic and fibreglass (GRP).

Can be painted

Sikaflex 291i is a popular adhesive and sealant product that can be painted over. The paintable nature of the product is advantageous because it allows users to maintain a consistent colour scheme in their projects, even when using different materials.
