after going all summer with no major issues i have to seal it up before winter starts. i'm glad that it is sticking and not coming back up (like the first two attempts).
the original project was to build up a sill along the garage door so that water would no longer flow into the garage. i used mortar mix and an additive which was a bonding agent. about 2/3rds bonding agent and 1/3rd water.
i had some bonding agent left and just painted a few layers on top as a sealer.
the issue i've found later is very tiny cracks due to inconsistent batches (i hand mixed everything and could not get it all placed at once).
so now i am at the stage where i am going to paint it to seal it and hopefully fill in the cracks.
buying an entire gallon of epoxy garage paint for such a small project was out of the range of the budget. so after talking to the guy at the paint store who has 30yrs experience i picked up a quart of a good primer and had him tint it a little into the grey. so it will probably look better than the current sill (even out some color variations due to some drips, etc.).
i'll first clean it up a little and then give it two or three coats (letting it dry well between coats).
mainly i just need to seal it up against water and salt getting in those tiny cracks and any further damage from freeze/thawing through the winter.
so, we'll see how this goes... still even with the additional $10 for paint the project is still low budget ($5 for the bag of mortar mix and $10 for bonding agent). and i have the time (sorta - garden season is still going on here until we get a harder frost).
