SECTION C: Fitting the Liner

Fitting the Linerlock

• Linerlock is the white plastic extrusion that the pool liner hangs from.
• Although the linerlock can be cut straight at a 90 degree angle a neater finish and better fixed liner will be achieved by cutting
at 22½ degrees. A mitre block will help with this.
• Take a length of linerlock and trim one end to approximatley 22½ degrees
Figure 19
• Clamp or hold this length of linerlock along the inside of one pool wall and mark the length. The correct length is to have the
linerlock for each wall meeting in the corner with only a minimal gap. Cut the other end to 22½ degrees.
• Lay the trimmed linerlock along the top of the pool wall and use a 3mm drill bit to make pilot holes starting 25mm in from each
end and at approximately 200mm - 250mm centres.
• Use the 3.5mm x 40mm screws to fix the linerlock to the inside of the wall
• The linerlock must be exactly flush with the top of the wall.
• Repeat this procedure for each wall ensuring that where the linerlock meets in the corners it is at the same level.
• It may be necessary to make some sections from two pieces as the Iinerlock is supplied in standard lengths, which do not divide
exactly into the correct sizes for all pools.
• Ensure that no linerlock screws are left protruding and have no sharp edges that could damage the liner.

Levelling the Floor

• If you have assembled your pool on a subsoil base rather than a concrete pad it is likely that the area inside the pool will have
become disturbed while you worked. If you used a concrete base this section is not required.
• Although the floor felt and liner could be fitted on uneven subsoil it is not recommended and a better finish with longer liner life
will be achieved by levelling the floor as follows.
• Draw a pencil line all around the inside on the pool wall 20mm up from the bottom.
• Remove any loose dirt from inside the pool.
• Use a dry mix of 5 parts sharp sand to 1 part cement and spread evenly over the floor.
• Use a straight edge and plastering float to achieve a flat, level finish.
• Do not let the sand and cement level go any higher than 20mm above the base of your pool where you made your pencil line.
• Moisture in the air and soil base will cure the sand and cement mix.
• Let the floor harden before proceeding.

Laying the Floor Felt Underlay

• Ensure the pool floor is clean and that no objects can fall into the pool. Any objects or dirt that remain in the pool when the liner
is fitted can either damage the liner or be unsightly for years to come.
• While climbing in and out of the pool make sure no dirt or debris is brought in. It is advisable to lay the floor felt underlay with
bare feet or just wearing socks.
• Locate the roll of underlay felt and underlay tape. Never use any other type of tape where it will come into contact with the liner.
• Lay out the felt to completely cover the pool floor, it will be necessary to trim the felt with scissors and join strips together using
the supplied underlay tape.
• Ensure that the felt is not overlapped at any point or creased as the double thickness will show through the liner.
• Where strips are laid side by side ensure the joint is butted up closely with no gap. Join sections of felt with the underlay tape.
• Avoid joining together edges that you have cut on site, most likely a neater finish will be achieved by joining machine cut edges.
