Have some TOA 213 Water Repellant to re-coat my terrace / pool surround with. I'm just painting it on myself, and don't want to do it during the heat of the day.

So, does anyone know if:

1) Better to apply when sandstone cool, ie first thing in morning

2) Better to apply when sandstone is warm / hot, ie start about 4.30pm

3) Doesn't matter one way or the other.

Thanks

Just make sure it is clean and dry.

It wont really matter if it is warm, or cool, however it will dry out much quicker the warmer it is.

I have never used this particular product, but the above is based on other stone enhancing products like Lithofin.
