Fixing your Mesh-Sling Patio Chair

The following steps will guide you on how to fix your mesh-sling patio chair:

The details of the steps above are explained next…

Step 1: Get a new sling

The first thing is to get a new sling. You must get the measurement of your chair first before making an order.

To find your chair’s width, take the measurement from one rail’s center to that on the opposite side. Then for the length, take a tape (the one used for cloth) and measure the curvature of one side of the rail.

There are different ways to get a new sling. You can get this Phifertex Wicker Weave Cane Weave Woven Vinyl Mesh Sling below from the comfort of your home if it suits what you have in mind.

Step 2: Divide your old sling into two

 Using a utility knife, cut the sling the middle in a downward motion and from each side of the rail, take out the end cap.

Step 3: Take out your old sling

At this point, you need to remove your old patio sling. Do this by sliding each half from the chair’s rails.

You will have to loosen the bolts holding down the rails to your chair’s frame. Do not remove the bolts completely.

The next thing is to remove the spreader bar.

If you feel your frame needs repainting, this will be the right time to do so.

Step 4: Attaching the new sling

Take out one rail completely.

With the hem side of the sling facing the back, slide the sling’s nylon rod in the other rail that you dint remove following its track.

Step 5: Tighten the sling

Now take the removed rail and slide it over the other rod that hasn’t been inserted into the rail.

Once you’ve done this, bolt the rail to the chair’s frame.

Make sure all the bolts on both rails are well tightened so that the sling will be rigid.

Step 6: Fit in the spreader bar

After step 5, you need to fit in the spreader bar. Performing this might be a bit difficult, so you’ll need to do the following:

i. Extend the rails a bit using a pipe clamp

ii. You can bend the spreader bar slightly so that it will fit

iii. Restore the bar’s shape by hitting it using a rubber mallet

Step 7: Cut excess nylon rods

Take a wire cutter and cut the excess nylon rods that appear outside the rail’s track. Then, fit the end caps on each of the chair’s rails.

Step 8: Enjoy your chair

You can now enjoy the comfort of your patio chair.

Fixing your Vinyl Patio Chairs

The following steps will guide you on how to fix your vinyl patio chair:

i. Get new straps.

ii. Fasten the straps.

iii. Bind strap around your chair’s frame.

iv. Pull strap to the opposite side.

v. Fasten the strap.

vi. Enjoy your chair.

Let’s discuss these steps in detail below…

Step 1: Get new straps

You’ll have to order for new vinyl straps. Before you do that, you’ll have to know the measurement of the chair.

Unlike mesh slings, you only need the length for vinyl straps.

To get the measurement, use a tape to measure the outer part of the chair’s frame; wrap the frame in the process. This measurement is for single-wrap straps that are exposed with either metal clips or plastic pegs.

For double-wrap straps, begin at a hole, then circle the tape completely around the chair’s frame. After this, pull the tape to the hole on the opposite side and repeat the pattern.

Make sure you get sufficient straps as well as pegs that will complete the refurbishing. You can still make use of metal clips if that’s what your chair uses.

The straps are usually cut to the required length with holes punched into the end of each side of the strap. The holes are where you’ll attach the clips or pegs.

Step 2: Fasten the straps

After getting your new vinyl straps, fasten them to your frame. Before you attach them, it is advisable you make them flexible. You can do this by soaking the straps in hot water; not boiling water.

After making them flexible, fasten an end of the strap to the frame by inserting a peg in the hole.

Step 3: Bind strap around your chair’s frame

Now that the strap is fastened, bind the strap around the chair’s frame. Make sure the peg is covered.

For single-wrap straps, don’t bind it around completely. Just wrap it halfway and then pull the strap to the other side of the chair.

Step 4: Pull strap to the opposite side

Hold the strap in the middle and pull it to the frame’s other side. Then hold it firmly with one hand and wrap it loosely with your other hand. Wrap it one and a half round the frame.

Step 5: Fasten the strap

Still pulling the strap, insert a peg in the hole. Move the loop created to cover the peg.

The strap is now fastened to the frame. Once it cools down, it will become tighter.

Repeat steps 2 to 4 for all other straps.

Step 6: Enjoy your chair
