Product Details

Micron Extra SPC is a multi-season antifouling paint that delivers premium protection in the harshest fouling conditions. The replacement for Interlux's extremely popular Micron Extra, SPC performs on boats of all sizes in fresh, brackish and salt waters.

From cold water to the tropics, Micron Extra SPC's self polishing copolymer formula keeps boat bottoms and hulls clean - even when your boat is sitting at the dock or on a mooring. Haul and relaunch without repainting. Boatyards prefer Micron Extra SPC's high solids, but VOC compliant formulation.

Quarts are available in Black and Blue. Gallons are available in Red, Black, Blue, Dark Blue, and Green.

In Good Condition: Remove loose paint by sanding with 80 grade (grit) paper. Remove sanding residue.
In Poor Condition: Remove antifouling paint in poor condition.

Bare Fiberglass: It is very important that bare fiberglass be properly prepared to prevent delamination of the antifouling paint. Begin by scrubbing the surface thoroughly with a stiff brush using soap and water to remove loose dirt and contamination. Flush with fresh water to remove the soap residue and allow to dry. Remove mold release wax using one of the following Interlux products, Fiberglass Surface Prep YMA601 or Fiberglass Solvent Wash 202 following the product label instructions. After the surface has been properly cleaned, follow one of the application systems below.

No Sand SystemClean the surface following the preparation procedure above. Apply one coat of InterProtect 2000E or Fiberglass No Sand Primer following the label instructions for applying the primer and overcoating with antifouling paint. Apply two coats of Micron Extra SPC allowing appropriate drying times.

Sanding SystemClean the surface following the preparation procedure above. Sand entire surface well with 80 grade (grit) paper until flat matte finish is obtained. Remove sanding residue. Apply at least two coats of Micron Extra SPC allowing appropriate drying times.

Blister Prevention System: Apply the Interprotect system for the prevention of blisters.

Bare Wood: Sand with 80 grade (grit) paper. Apply first coat reduced 10% with Special Thinner 216. Fill seams with Interlux Seam Compound 30 (if necessary).

Steel: Contact Interlux for further details. Method Two coats should be applied. Apply an extra stripe coat in areas of high wear such as chines, rudders, sterngear and any leading edges.

Mixing: Thoroughly stir until product is mixed to a uniform consistency before use.
Thinner: Thinning is not recommended. Antifouling performance can be compromised if correct dry film thickness is not applied. If thinning is necessary, do not thin more than 10% by volume using Special Thinner 216 or BrushEase 433.
Ventilation and Humidity Control: Ensure adequate ventilation during use. Other: For application of Micron Extra SPC to underwater metals such as stainless steel, cast iron, lead and bronze, see Interprotect bulletin. Antifouling should only be wet sanded. Never dry sand or burn off old antifoulings. True color will develop after immersion.
