The rule of thumb is, as long as the substrate is porous you can use LastiSeal. You can even use it for sealing fibrous wood! This ensures that the interior is protected from severe weather and penetrating damp, but any residual moisture or water vapour is still able to escape.Stormdry only requires one coat, and we found that it was touch-dry after a few hours and water repellent after two days and largely water resistant after 28 days. If you want to be sure that your salts and mould won’t return, you can apply a waterproof render or fit a mesh membrane to your wall before replastering. Treat your internal walls with anti-mould cleaner and salt neutraliser before redecorating to prevent the reappearance of salt deposits and mould
