No covered employer which contracts with any contractor or subcontractor who is a covered employer under the provisions of this chapter shall make final payment to such contractor or subcontractor for any indebtedness due, until after the contractor or subcontractor has paid or has furnished a good and sufficient bond acceptable to the director for payment of contributions due, or to become due, in respect to personal services which have been performed by individuals for such contractor or subcontractor. Failure to comply with the provisions of this section shall render said covered employer directly liable for such contributions; and the director shall have all of the remedies of collection against said covered employer under the provisions of this chapter as though the services in question were performed directly for said covered employer.
