The instant repair patch
for virtually any surface.
Instapatch is a UV-cure repair patch that bonds permanently to virtually any hard surface. Peel off the backing, press it into place, and cure it under daylight or a UV lamp. No tools, no mixing, no specialist knowledge required. Waterproof from the moment it cures.
One patch,
hundreds of repairs.
Instapatch bonds to metal, asbestos, fibreglass, plastic, wood, concrete, and most painted surfaces. It is used by roofing contractors fixing asbestos and felt roofs, marine engineers patching boat hulls, vehicle bodywork repairers, farmers fixing water tanks, and homeowners sorting leaking gutters. If it is hard and relatively clean, Instapatch will stick to it.
Four steps.
One permanent fix.
The entire process takes between 15 and 45 minutes depending on how strong the UV light is. On a bright summer day outdoors you can be done in a quarter of an hour. In overcast conditions or indoors with a UV lamp it takes a little longer. Either way, once it has cured you can drill it, sand it, and paint over it.
Clean the surface
The surface needs to be clean, dry, and free from dust, grease, wax and loose material. On smooth surfaces like fibreglass or metal this takes seconds. If there is dirt, moss or loose paint, clean it off and let it dry first. Most repairs don't need primer. On a slightly textured surface the UV curing primer can help; let it dry fully before applying the patch.
Cut to shape
Only open the packet when you're ready to use the patch, as it can start to cure within minutes once it's out. If you need a different shape or size, cut it with ordinary scissors while it's still in the packet.
Peel and press
Peel away the white release film to expose the tacky resin surface, then press it firmly onto the repair area. Instapatch is pliable enough to mould around curves, into cracks, and over bolt heads or raised edges. Work from the centre outward and apply firm pressure across the whole patch, paying particular attention to the edges to prevent any lifting once it cures.
Cure under UV
Peel off the top film straight away for a matt finish you can paint, or leave it on for a gloss finish that can't be painted. Then expose the patch to UV light. In direct summer sunlight it achieves a full hard cure in around 15 minutes. In weaker light or indoors under a 365nm UV lamp, allow 30 to 45 minutes. Once cured the patch is rigid, waterproof, and permanent. It can be drilled, tapped, sanded smooth, and painted over with most water or solvent-based paints.
Contours to
any shape.
Before curing, the resin matrix in Instapatch is soft and highly conformable. It will press into hairline cracks, wrap around cylindrical pipes and gutters, span across corrugated roofing profiles, and follow the contours of curved panels without lifting at the edges. The patch stays where you put it while it cures, which means no clamping, no holding, and no assistance required.
Use ordinary household scissors to trim Instapatch to any shape while it is still in the protective film. A rectangular patch with rounded corners is ideal for most repairs. For pipe repairs a long strip works well. For a bolt hole or a small puncture a circular patch is the neatest solution. Because you cut it yourself you are never left with a patch that is the wrong shape for the job.
One patch.
Built for the job.
Instapatch uses an isophthalmic resin matrix that cures under UV light to a hard, permanent, waterproof repair. It covers virtually every repair application, bonding to metal, fibreglass, asbestos, plastic, wood and concrete, and is available in three sizes plus a continuous roll for trade use.
