A one step solution to algae and mound problems on boats, sails, canvas and marinas - protect your investment


Sailclere - Treatment & protection against mould & algae for sails and boat covers

Protection against premature degradation

Sailclere is a new technology which prevents the colonisation of the canvas, polyester (Dacron®) or nylon surfaces of sails and covers so they stay cleaner for longer and prevents premature degradation from mould and mildew.

Prevent & treat stains

When applied in accordance with the instructions, Sailclere will prevent stains caused by algae, mould and bacteria, protecting the sails when packed away. Sailclere is quick and easy to apply using the supplied applicator attached to a garden hose with a standard Hoselock™ connector or similar.

With new surfaces there is no need to pre-clean, however where canvas has already been used then it may be necessary to wash the surfaces with a suitable mild detergent, such as Boatclene. Extensive staining already within the material will not be removed completely, however treatment with Sailclere will prevent further staining and prolong the life of the sail or cover, by preventing premature degradation from mould and mildew.

Sailclere does not weaken the fabric or stitching, nor promote discolouration of the material. Apply prior to putting away for winter and for off-season protection from algae, mould and mildew stains during storage. Apply again after removal from storage.

Environmentally Friendly

Environmentally friendly Sailclere controls 99.99% of all known algae, mould, bacteria and fungi. It contains no toxic chemicals such as creosotes, aldehydes, chlorine, alcohols or silicones and is quick, easy and safe to apply with no need to worry about overspray onto other surfaces.
