Step - 1 Set out
The set out of your fence is the first and most important step to ensure the fence fits correctly.
- Measure your area and draw plan on paper first.
- Mark the outside extremities of your fence on the concrete or timber surface.
- Stretch a chalk line between marks parallel with the outside edge of your slab or deck, generally we allow 100mm from edge to avoid chipping or breaking of edges when core drilling. 100mm in from edge will be you centre of glass line.
- Pull the chalk line tight and flick the line.
- Mark the panel lengths on the chalk line and also mark the gaps between the panels.
- Generally we place the spigots 25% in from the edge of each panel. The good thing about ‘friction spigots’ is that these can be adjusted to suit as there are NO HOLES required in the glass.
- For Example - if a glass panel is 1000mm the spigot breakdown is 250mm in from the edge of the glass. Leaving 500mm between the centre of the two spigots.
- The formula to work out the centre of your core holes is to measure the length of the panel and divide it by four = X.
- X is the measurement from the end of the panel to the centre of the core holes.
- NOTE: It is a good idea to check all measurements twice. All measurements should be with 2-3mm.
- This is the centre of your core hole or the centre of your base plate spigot.
- Find the centre of the gate position and mark with chalk line. The gate opening for standard spring hinge gate is 830mm. Actual gate size being 800mm allowing 16mm for hinges and latch.
- You are now ready to core drill your holes or fasten to decking.
Step 2 - Core Drilling
- When your fence is on concrete or tiled services we recommend core drilling as it is much stronger than based mounted and aesthetically more appealing.
- Using a core drill is pretty simple, simply select your size core bit, we recommend 72mm diameter core bit. It is important that read the instructions from you local equipment hire place before starting. A little trade tip, is to use a bit of rubber/timber about 20mm thick. Make a guide hole through the rubber the same size. When you start each hole, use the guide to mark the holes about 5mm. Then remove the guide and start core drilling. REMEMBER always use water when core drilling.
- Drill a maximum of 200mm into concrete, generally 180mm from top of tile to bottom of holes is perfect. DO NOT put to much downwards pressure on the core drill.
- Break the concrete using a hammer making sure you do not chip any pavers or tiles.
- Use flatten out tongs to pull the concrete out of the hole. You may also need a small jack hammer to break away some concrete.
- Wash away any concrete slurry, we have found a wet/ dry vacuum works best to clean water and slurry from area.
- You are now ready to stand up your fence. The standard height panels are all 1200mm high so you know you will always comply.
Step 3 - Getting your levels right
- Starting at your gate position, set a block using timber, window packers etc to set a height of 50mm at the back of the gate.
- Each panel will now need two blocks on the outside edges of the core holes.
- Using a spirit level; level across to the blocks using window packers for each panel. Do this the whole way around the fence. What we are trying to achieve is a completely level blocking that each glass panel will sit on. Making sure the blocks do not exceed 100mm.
Step 4 - Attaching spigots
- The ideal gap for a frameless glass fence is 50mm but may vary depending on the slope of the fence line.
- Place two timber blocks next to a solid wall. Place the glass upside down (you can tell this by the compliance stickers in the corner of the glass, this needs to be down the bottom).
- Mark the same breakdown as your plan (1000mm wide = 250mm in from edge)
- Place 2 x 1mm packer at bottom of spigot and remove sticky backing of 1mm side packer and attach to side of spigot.
- Slide the spigot over the glass, keeping all packers nicely against spigot.
- Tighten 4 x grub screws with allen key.
- Make sure spigot is square to the glass. Repeat for each spigot.
Step 5 - Standing up your glass
- Once you have both spigots fasten properly and tightened, place dress ring upside down over spigot. Tape dress ring to the glass so it doesn’t slide down when placing panel in position.
- Turn the panel over so the spigots are facing the ground.
- Slowly walk panel over to position. This is 2 person job!!!!
- Place the spigots in the already cored out holes and place the bottom of the glass on the blocks already set up. Level and plumb glass and secure in position.
- Once first panel is secure, repeat with next panel. Clamp both panels between the gaps using 200mm timbers screwed together as shown in pictures.
- Measure your spacings between panels as you go, remembering to check heights and adjust accordingly. and adjust accordingly.
- Use two clamps per panel, top and bottom. Place the top one level with the top of the glass and use this to screw timber stays together.
- Make sure all panels are plumb and level as you go. Use timber stays to secure in perfect position. You will need a timber stay every 2-3 panels.
- Use bricks, pavers or sand bags to put weight on the stays so the fence will not move.
- TRADESMAN TIP once you think you fence is in perfect position, use a string line to check. Place the string at the top of the fence in the centre of the 12mm glass, pull string tight to the over end of the line. Place this end in the centre of the 12mm glass also. If the fence is perfectly straight, the string line will run perfectly through the centre of the glass. If not adjust accordingly.
Step 6 - Grouting the holes
- Once your fence is perfectly positioned and secured correctly, you are now ready to grout the core holes.
- We recommend any Class A structural non shrink grout.
- Read instructions on mixing properly and mix to flowable liquid.
- Using a funnel, slowly pour the grout into the holes. Do this very slowly as it is very easy to over pour and make a mess.
- Fill all holes. Wait 20 minutes then check to see if any of the holes need topping up.
- Allow a minimum of 24 hours for grout to fully set.
- After 24 hours, check grout is hard with a screw driver. If any need topping up again, do so now.
- Remove all timber blocks and stays.
Step 7 - Fitting the gate
- Under AS1926.1-2007, the gate must open away from the pool.
- Fit the latch to the gate panel as per drawing supplied.
- Attach the hinges to the gate, put two 50mm packers underneath the gate and carry into position, sitting the gate on the packers.
- Screw the hinges to hinge panel.
- Adjust spring pin as needed.
Step 8 - Clean and admire
- Give your new frameless glass pool fence a clean with water.
- Sit back and admire!!!!
