Q: How much 406 do you need to thicken approx 1 gallon of 105 to get a peanut butter consistency? (or not quite peanut butter, but so it can be troweled with a groove trowel)
5 years ago1 Answer
A: You must be looking to do an incredible amount of silica work to be mixing up a gallon of this stuff. From my experience doing four shots from the West pump will yield about 1/2 of a 1/2 quart mixing cup at the consistency you are asking about. Just guessing but mixing up 4 or 5 of these cups burns up about a third of a 5.5oz container.

Q: Does this product work well to fair a keel joint ?
10 years ago4 Answers
A: By weight, 406 is really light. 404 is heavy. So when I want to do something that needs beefiness to it I'll use 404 rather than 406. Although not sure about keel work, I use a motor:)

Q: Will this penetrate wet balsa core in a boat deck or coach roof or does all of the wet wood need to be removed first?
11 years ago4 Answers
A: West Systems could likely provide a more technical answer, but if you want to get deep penetration into compromised wood, I apply CPES first to stabilize the wood...as much as the wood will soak up...let that cure.. then come back with neat epoxy, then thickened epoxy while the neat epoxy is still damp.

Q: Are there health risks when using WEST System 406 Colloidal Silica filler?
11 years ago4 Answers
A: I assume you are wondering if the colloidal silica becomes airborne and inhaled, could it cause disease? I don't know the entire answer, but in my use of the material, it doesn't seem to become airborne. I use it in small __quote__hobby amounts__quote__ in high power rocketry for fin fillets. Even though it is very fine and lightweight, it tends to stay in the cup while I'm stirring it into the epoxy. I haven't felt the need to put on my mask while using the material (and I'm pretty compulsive about using a high-quality filter-mask when cutting or sanding fiberglass, for example.) It's a great question, but at least in the small amounts I'm mixing and the way I'm using it, my opinion is it is safe.

Q: can these products be used for exterior wood?
12 years ago2 Answers
A: Yes, West System can be used for exterior applications as long as it is painted or varnished. Bare West System is susceptible to UV damage and will peel and degrade quickly if not covered. I have fixed alot of wood boats with it... even my wife's china. It's amazing stuff! Good luck
