Bottom Protect 70™ - Epoxy High Build - 70% Solids Barrier Coat Primer

Bottom Protect 70TM is a two-component epoxy primer with excellent adhesive properties on sanded fiberglass and as an anti-corrosive primer on properly prepared metal substrates such as aluminum, steel, and lead.

Surface Preparation: Surface must always be clean, dry, and properly prepared prior to painting. Failure to do so will lead to eventually blistering and/or peeling. High-pressure freshwater clean and allow to thoroughly dry prior to painting.
General Application: Primarily for use as a high build barrier coat primer on sanded fiberglass but can also be used as a general-purpose primer on metal surfaces. Apply by spray, roller, or brush. If thinning is desired, see above. Add up to 10-15% by volume for spray, 5-7% for roller or brush. Apply additional coats if needed to meet dry film thickness requirements. Allow 20-30 minutes induction time after the Converter is added and before adding any thinner.
Mixing and Thinning: Shake or mix each component thoroughly. Add the Converter Component to the Base Component and stir thoroughly. Continue to stir while using.
Induction Time: 20-30 Minutes at 70-75 deg. F, longer at lower temperatures
Existing Painted Surfaces: First, ensure the existing surface is compatible with a two-component epoxy and if acceptable, thoroughly roughen the surface with 80-120 grit sandpaper to provide sufficient tooth for maximum adhesion. Wipe off sanding dust with Thinner 974 or 975, allow to dry, and apply the first coat of Bottom Protect EHB.
Bare Fiberglass: Thoroughly remove any surface contaminants or mold release agents using Dewaxer 973. Read and follow instructions carefully. Sand surface to a matte finish using 80 grit sandpaper. Remove sanding dust with any of the following thinners, 973,974 or 975, allow to dry, and apply the first coat of Bottom Protect EHB.
Bare Metal Surfaces: Steel - Sandblast with standard angular grit media to a blast profile of 1.5-2.0 mils. Remove blasting dust and apply two or three coats of Bottom Protect. Allow to properly cure and apply antifouling paint or top side finish.
Bare Aluminum: Sandblast with a non-metallic media to a blast profile of 1.5-2.0 mils and proceed as above. If blasting is not practical, grind the surface with a disc sander and a 36-60 grit wheel. Remove grinding dust and apply one or two coats of Blue Water Strontium Chromate Epoxy Primer followed by two coats of Bottom Protect EHB and then the appropriate antifouling paint or top side finish.
