Product Description
Metaclor Underwater Primer is a modified chlorinated rubber based primer designed for wood, steel and GRP. It also contains Zinc Phosphate, which provides added protection from rust and corrosion when applying to steel surfaces.
The primer is designed for use before one of the Teamac range of antifouling coatings. If you’re not sure which antifouling coating you require, the properties and compatible surfaces for each are listed on the product pages. You can also contact us by web chat, phone or email, where our team will be able to answer any questions you have about this or any of the products we supply.
This coating is also suitable for use as a sealer coat over most conventional systems. If you’re not sure if it would be compatible with a your current coating, please contact us, and we will be able to let you know.
Metaclor Underwater Primer provides a Matt finish and can be applied by brush or airless spray. The coating is touch dry in 30 minutes and hard dry in 6 hours. When overcoating, leave a minimum of 8 hours before applying the next coat.
Surface Preparation
Ensure all surfaces are clean, dry and free from grease, oil and any other contaminates. Bare steel should be free from dust, rust and scale. Blast cleaning to SA 2½ is recommended. If blast cleaning is impractical, mechanical cleaning should be employed but hand cleaning does not
clean the steel to the required degree. Any oil or grease should be removed with solvent before de-rusting. Where blast cleaning is carried out after assembly, special attention must be paid to edges, corners, nuts, bolts welds, etc. Welds should, if necessary be ground and all weld spatter, slag etc. must be removed.
Existing painted surfaces – Surfaces should be cleaned, degreased and sanded to ensure an adequate “key” is produced. Remove all loose and flaking material and treat bare areas as new substrate and prepare accordingly. Apply to small test area first to ensure no reaction with conventional paints. Maintenance: Remove all marine growth, oil and grease. High pressure wash with fresh water. Remove all loose coating and power tool clean areas of breakdown. Bare areas should be spot primed to full film thickness prior to application of full coat.
Mixing Instructions
Mix well before use.
Application Conditions
As dictated by normal good painting practice. In confined spaces, provide adequate ventilation during application and drying.
Preceding Coat
Directly onto base prepared steelwork or wood. Can be applied to old, aged coatings including antifouling after recommended preparation.
Subsequent Coat
Teamac Antifouling paints or part of a specified Teamac anti-corrosive system.
Remarks
Apply to small test area first to ensure no reaction with conventional paints.
Estimated Coverage
6.5-10sqm per litre
Preparation:
To ensure a durable and effective bilge paint application, it’s crucial to properly prepare the surface. Start by cleaning the substrate thoroughly to remove any dirt, grease, or oil. You can use a degreaser or mineral spirits for this step. Next, inspect the surface for any rust or old paint. If present, remove the rust using a wire brush, sandpaper, grinder or suitable rust remover / treatment. For old paint, use a paint stripper or sand it down until you reach the bare metal. Once the surface is clean and free of rust and old paint, sand it with fine-grit sandpaper to create a smooth and slightly roughened surface for better paint adhesion. Finally, wipe down the steel with a clean cloth to remove any dust or debris before applying our rust-inhibitive marine primer. After the primer has dried, you can proceed with applying our high build marine undercoat and then one but preferably two coats of the bilge paint.
Application:
Best results are obtained in warm (minimum 10°C), dry conditions.
Mix thoroughly for approximately 2 minutes using a drill stirrer. A wooden batten at least 25mm wide is also ideal.
Apply an even coat using a brush, short to medium pile roller on smooth surfaces.
For spray application by either airless or conventional spray a dilution ration of no more than 10% is recommended with Palatine White Spirit by volume.
A second coat can be applied at full strength. This will prolong the life and performance of the coating.
For application onto wooden surfaces, a minimum of two coats is recommended.
Drying Time @ 20ºC: Drying times will be extended at low temperatures.
Do not apply when ambient temperature falls below 5ºC or relative humidity exceeds 90%.
Surface dry @ 20ºC: 1 hours
Hard dry @ 20ºC: 4 hours
Overcoat@ 20ºC: After 8 hours (temperature dependent).
Theoretical Coverage: 12 – 14m² per litre.
(Coverage rate can be affected by such variables as type and condition of substrate, type of application equipment and individual method of application.)
Storage: Store in temperature range 5-40ºC
Thinners: White Spirit
