The sparkles are suspended randomly in the resin so will keep a consistent glitter effect and will not sink to the bottom or float to the top. These resins need to be mixed with the hardener only, they should not be diluted as this will affect the sparkle. LOW VISCOSITY Hardener must be used in order for the resin to cure. Mix 2 parts colour resin with 1 part hardener by weight. We use Up Mail’s courier service to deliver our resin products at a cost of £8.00 (Up Mainland). This is a 2 day service operating from Monday – Friday.
