Hi there it is water resistant once cured not sure what you need it for. wouldn't use it for an outdoor pond i used it for pointing small bits inside and out. Fire cement is a good option internally but externally i would consider external quick set cement. Bear in mind unless it's a very small repair these tubes can be annoying and don't hold much i prefer tubs

Q: How long does it take to dry in this winter weather on an exterior wall (not subject to precipitation)?

Hi not sure in this very wet weather but repointed my brick work after chiselling out for outside lights in December 2019 set and water proof in about 24 hours in dry weather looks good and easy to apply if you cut nozzle the same size as mortar joints has to be that large as it feels like real sand and cement and looks like it when dry (light colour)will buy again for garden wall lights I recommend this product

Q: After squirting it into the hole, what type of tool is best to use to level off the surface?

We used this product to repoint the brick joint where the mortar was missing and we used a jointing tool to smooth the surface. Depends where you want to use it as to which tool to level the surface.

Q: Can I use this as grout for tiles?

I’d use proper tile grout it would be much easier and cost effective
