For Any Users Of Sikadur AnchorFix-2 (Sika Anchor Fix) For Anchoring Screws In Concrete

[Bob]

Hello,

Regarding the product "Sika Anchor Fix" also known as Sikadur AnchorFix-2 used e.g. for anchoring and bonding metal screws in concrete:

Question: must the hole in the concrete that the metal stud is going into to be anchored be "absolutely" dry, or is it that a little moisture or dampness won't effect the bond strength by any meaningful amount ?

Couldn't find anything on their data sheet regarding this.

Thanks, Bob

what did the person on the other end of the 800 listed on the package say?

If the holes are really damp (casual rain, whatever) rinse them out with acetone and blow dry with compressed air. Acetone is a good general epoxy tolerant cleaner that happens to be water soluble. Since many of the common epoxy hardeners are amine derivatives, they are fairly water tolerant. Odds are you won't have any problems in the average situation. If the Sikadur is not a full spec epoxy, another supplier might be a better choice.

SiKA makes a number for AnchorFix-1,2,3 & 4

I only have experience with -1 & -3.... I know that they are dampness tolerant.

I have used them in damp holes (standing water removed with shop vac)
