IRHSP Primer Medium
Irresistables Heat Set Paint (IRHSP) Primer is a high-quality, odourless, non-solvent medium designed to prepare vinyl surfaces prior to painting.
This advanced formula creates a smooth, transparent base layer that helps paint adhere evenly, while gently filling micro imperfections in the vinyl. The result is a beautifully prepared surface that allows for smoother colour application and more consistent layering.
Easy to apply with a sponge, this primer adds just the right amount of texture to support professional, even finishes across your reborn work.
 
How to Use
Thoroughly wash and prepare your vinyl
Apply a small amount of primer to the surface
Use a sponge to gently pounce and distribute evenly
Heat set at 265°F (130°C) for 9 minutes
Allow to cool before beginning your paint layers
Important: Do not exceed 350°F (175°C) during heat setting.
Top Tips
Use sparingly — a little goes a long way
Applying too much may prevent proper drying and leave a soft or tacky finish
Build up in light layers if needed
Creates the perfect base for smooth, even paint application

Heat-set painting pathway
This product belongs to the IRHSP/Irresistables heat-set system. Heat-set paints and mediums require curing at approximately 130°C, normally for around 10–15 minutes per layer in a suitable halogen oven. Follow the maker's instructions for the specific product and do not present it as compatible with an air-dry-only workflow.
