Application: Apply Monu-U-Mask with a foam roller, putty knife, or silicone brush. Mon-U-Mask should be at least 20 mils thick on a smooth surface and 30 mils thick on a porous surface. Applying too thin will make it more difficult to remove and may also not provide complete protection. Allow product to cure fully. Paint. Allow paint to dry. Peel off the Mon-U-Mask by simply rubbing an area until lifting is achieved and peel. If you find it difficult to peel, apply an additional layer, let dry and peel again.

Note: Dry time varies by temperature & humidity
