Getting rid of weeds and moss from gravel and patio

Hi, could anyone recommend a cheap but effective way to get rid of weeds and moss from constantly regrowing on my patio and gravel, please? I'm looking for a solution that requires minimum effort and time. I recently clearer all the cracks out between the patio blocks and refilled it with sand, but the moss and weeds have reappeared after only a couple of months.

    I did the same as you with the sand and found that weeds only need the smallest hole to take root.

    I bit the bullet and have concreted between my slabs, taking advantage of more time on my hands due to covid.  Just did a bit at a time. 

    I suggest you might want to spray with roundup or similar but I'm afraid you'll find the weeds will find a way back through whatever you do (but I'm ready to be proved wrong). 
    Just my opinion, no offence 🐈

    neudorff weedkiller. It is one of the very few weedkillers that kills moss and weeds. It is on the pricey side but you will not be wasting your money and it goes a long way.
    Out of interest, what sand did you use?

    Thanks for the reply, I used sand designed for paving and jointing, but I don't think it's anything special.

    The last time we re-sanded the block paved drive we used fine sand with weed inhibitor (Wickes).  2 years later we just get the odd weeds that are easily zapped with weedkiller.

    I wonder if its a fine sand to be mixed with cement..for jointing and paving? This would have a binding property and explain why moss and weeds grow in it. This may sound slightly padantic but the more angular the sand granules, the easier they will drain and weed seeds will find it difficult to germinate and moss certainly won't grow in it. For example, you will rarely find weeds and moss growing on sandy beaches but leave a bag of builders bricky sand open to the elements and it will have moss and all sorts sprouting.
