Correct Sealant

[Pete68]

What's the best type of sealant for caulking a wooden to PVA step out onto a patio. I've currently used white sillicone and general purpose frame sealant but doesn't appear to be the correct type of sealant. Any help, much appreciated.

Use a "low modulus" one, Pete.............
