Repairing PVC Bouncy Castles

Gluing PVC IrelandPVC Bouncy castle repair

Inflatables are becoming more and more popular in Ireland. Amongst the most popular are bouncy castles & balls, inflatable games, sumo suits and rolling balls. Be it for kids celebrations, team building days or other events, at any one time there are hundreds of inflatables in use up and down the country. Bouncy castles are typically made by from 600g PVC/Nylon or sometimes 800g PVC/Nylon and must conform to EN14960 European Safety Standard..

Since your customers are having such great fun, it is lightly that the inflatable will be damaged. Luckily, we are here to help.

Industrial PVC & Nylon bonding forms one of the cornerstones of our business, and through our partner Alpha Adhesives, we offer a range of adhesive solutions for repairing tears, rips, and holes in inflatables. So knowing how to repair a bouncy castle, regardless of how small the job, is extremely valuable information!

There is a relatively easy way to repair a hole in PVC/Nylon. First of all, cut the repair patch extending 50 mm from all sides of the damaged area. Make sure to round the corners of the patch as a square cornered patches are more likely to catch and peel than rounded ones! Trace the area of the patch on the damaged surface with a felt tip pen.

Using 180 grit sandpaper, lightly buff the whole bond area, this includes the damaged area on the inflatable and the back of the repair patch. The fabric should look like a dulled version of the normal inflatable surface. Be careful, don’t buff down to the point where the threads are visible. The goal here is to remove the surface glaze of the fabric, without removing excess coating!

Clean the buffed surfaces with a lint free cloth which has been dipped in T 559 thinners. The T 559 removes any contamination such as oils etc, which may otherwise inhibit the adhesion of the adhesive.

Next comes the adhesive……..

After the surfaces (both damaged area on the inflatable and the underside of the repair patch) have thoroughly dried from the cleaning step, next comes the adhesive. Both Alpha S1588 nitrile adhesive and Alpha S49 polyurethane adhesive have become the standard for this type of repair. S1588 is a single component adhesive for small, fast repairs whereas S49 is a two component adhesive for the best repair jobs. S49 has shown particular application in repairing hold down straps.The S1588 adhesive is used directly from the supply tin. For using the S49 two component adhesive, decant the crosslinking agent into the adhesive and stir gently for five minutes. The crosslinking agent significantly increases bond strength and heat resistance.

Next apply a very thin layer of the selected adhesive to both surfaces, using a stiff bristle brush.

After the first layer of adhesive is just tacky apply another thin second layer of adhesive to both surfaces. Test for how tacky the adhesive is with a gloved finger or by touching knuckles to the glued area. The glue should feel gummy, but should not stick to the gloved finger or knuckle. Do not use bare fingertip to test for tackiness. Fingers contain oils that will be left behind and effect the bonding quality of a repair job.

Join the two surfaces together when the adhesive is tacky to the touch but does not transfer when tested with a knuckle. Be careful with this step! Make sure to place the patch in the correct area. Alpha S1588 & Alpha S49 are contact adhesives, therfore, once the surfaces have contacted each other, they cannot be moved!
