Thermal paste is by no means a glue. Its an interface material.
There are a few choices for your needs though.
"Frag" tape aka Thermal adhesive tape or epoxy.

Frag tape is not a good performer for heat transfer compared to thermal pastes.
Epoxy works well but is permannent for the most part.

What we have found is that using "Arctic Silver " or "copper paste " does have enough strenght with surface tension to hold most smaller heat sinks on to a surface.

Such as vid card heat sinks and the like. Still you need a retension mechanism for larger heat sinks.

If you need a glue like compound, may I suggest "Arctic Silver Epoxy".

From the folks that brought you Arctic Silver, only it's a two stage epoxy.

Thermal Grease 'works' because it effectively displaces air. The grease conducts heat better than air. It should be applied fairly thin using the edge of a razor blade or credit card. The precise 'thickness really depends on how smooth and flat the bottom of the heatsink is. Real smooth gets a thinner layer.

how should i go with it if i dont want the heat sink to fall off?

Poit has about the best guides on the net for these sort of questions. He even has some animated gifs showing you how to apply thermal past.

Fall off?

What are you putting it on? Video card, I guess.

Like I said Arctic Silver 2 part Epoxy.
