Frequently Asked Questions

What is the shelf life of unopened package?

12 months from Date of Manufacture.

How long does it take to cure in sunlight?

The stronger the sunlight the faster the cure. Generally, in normal sunshine, material will cure in 5-15 minutes but in cloudy weather can take up to one hour. Curing can also take place in cloudy conditions, as UV is always present in the atmosphere.

How long does it take to cure under UV lighting?

Again the stronger the UV light, the quicker the cure. Material will cure anywhere between 10 and 30 minutes depending on the power of the UV light.

Will it stick to any surface?

Patch Pro will stick to any surface except for Polypropylene (PP)

Is Patch Pro harmful to skin?

Patch Pro is a non-hazardous material, however, it is recommended that anyone with sensitive skin should wear appropriate protective gloves when handling the material. Full Health & Safety information available in the Safety Data Sheet available for download on our website.

Can multiple layers be applied?

Yes, multiple layers can be applied, however, we would not recommend anymore than five layers to be applied at any one time. When adding layers additional curing time should be allowed in order for each layer to fully cure.

What sizes is Patch Pro available in?

Available in 3″ x 6″, 6″ x 9″ and 9″ x 12″.

Is preparation of a surface required?

No, surfaces only need to be clean, dry and free of any loose contaminants.

Can Patch Pro be used on wet surfaces?
