How long after applying L3000 should I wait to apply this?

Wait at least 5 days after applying the L3000.

I have a concrete porch that has never been sealed, was painted but I will strip all that off. is this product appropriate?

If your concrete paint is stripped off and the concrete is porous/absorbent, the SX5000 can be applied (usually two coats of sealer). The SX5000 is a natural looking sealer that functions as a water/salt guard when adequately applied.

We live in a townhouse with concrete outside window sills and a concrete step entering the house. Is this product appropriate? Shiney?

You can use the SX5000 as an exterior water repellent for the window sill and step (it's appropriate). The SX5000 provides a matte finish (natural looking).

Is it suitable for flagstone coping around a pool?

The SX5000 works well as a water/salt guard for flagstone and will not make the surface slippery when properly applied. Flagstone is dense, your stone might only absorb one coat or two light coats (run a small test area).
