Teamac Antifouling 'A' Plus is a premium physically ablative product for the underwater areas of marine vessels or underwater structures. Suitable for domestic and commercial vessels with aluminium, steel, wood, or GRP hulls. Teamac Antifouling 'A' is a modified composition containing a high level of copper thiocyanate to give good antifouling performance.
It is formulated for vessels with a maximum speed of 25 to 30 knots.
Expected functional life of the coating is 18 to 24 months. H.S.E. Approval No. 8960
Colour: White, Black, Blue, Red.
Remove all loose and damaged existing coating and all marine growth. High pressure wash with fresh water. Areas of breakdown should be blasted or power tool cleaned. Touch up with Teamac Metaclor Primer to the full existing film thickness. Prior to the application of the full coat ensure that surface is clean and free of all contaminates.
On aluminium, ideally abrade the surface to provide a "key", clean, then immediately coat with Metaclor Primer. When dry apply 2nd coat. If abrasion is not possible, the surface must be degreased and treated with 'T' Wash/Mordant solution (leave to react for 2 hours), follow the instructions on the pack. When this is clean and dry apply the 2 coats of Metaclor Primer, then 2 coats of Antifouling 'A'.
On exposed metal and wood.Prime first with at least 2 coats of Teamac Metaclor Underwater Primer (but not more than 3).
On GRP lightly abrade exposed surfaces and apply 2 coats of Teamac Metaclor Underwater Primer.
New steel: Abrasive blast clean to Sa2½ and apply Teamac Metaclor Underwater Primer.
If applying onto shop-primed steel ensure that surface is dry and clean, and areas of damaged primer are suitably cleaned prior to the application of Metaclor Primer.
