Product Placement
Installation, erection
Install EasyStart starter strip to siding manufacturer's instructions. Starter strip is required to space siding a sufficient distance from the wall to allow insertion of Fullback panels. Allow minimum 3/8 inch (9mm) space between starter strip and adjoining siding accessories.
Install EasyPost inserts under vinyl siding corner posts.
Install vinyl siding in accordance with siding manufacturer's instructions, inserting Fullback panels behind each course immediately prior to nailing. Nail siding in position through the Fullback panels behind.
Cut Fullback panels using a sharp, thin-blade knife.
Butt adjoining Fullback panels together leaving no gap (panels compress sufficiently to absorb expansion without buckling).
