Clean all wooden surfaces using a brush or vacuum cleaner.

To aid brushing out on any timbers which are very dry or remain dusty, apply a little water to the surface before the application of ACS Ecobor 20 Gel.

Application Method:

Apply a generous brush coat of ACS Ecobor 20 Gel, taking care to ensure that end grains, corners and joints are well treated. Brush apply to any surfaces exposed by cutting after initial treatment.

Brush the ACS Ecobor 20 Gel well into the surface taking care not to overload the brush with product, particularly on overhead, horizontal faces.

ACS Ecobor 20 Gel may be used in outdoor conditions provided that the timber treated is then protected from weathering by an appropriate coating or sealant.

As a surface application the gel will not penetrate through paint, varnishes or other coatings and these should be removed before treatment. ACS Ecobor 20 Gel can be injected through predrilled holes in areas where paint and coatings cannot be removed.

Clean all tools, brushes and equipment with water.


By Brush: 1 litre to 2 - 2.5m² of timber surface. Large dimensional timbers may need more than one coat or additional treatment with ACS Ecobor 40 Paste.

By Injection: Apply as necessary or until refusal through pre-drilled holes
