Pull, push or scrape off the old silicone. Does not damage tiles.

The CORNERTAPE® Silicone Remover Std. is made from a high grade composite material which makes it more durable than just normal plastic. It has an added ingrediant to make it harder than normal but not so hard that it will scratch the surfaces.

You must remove 100% of old silicone from surfaces otherwise the new silicone will not stick. On uneven surfaces we recommend using the Residue Remover to remove the final bits.
