Drying time is optimised for professional use:
- Touch dry after 1-2 hours
- Overcoatable with water-based paint after 12-16 hours
You can apply this blocking wood primer using various tools, including spray gun, brush or roller, which provides flexibility in application depending on the size and nature of your project.
Applications
Caparol Iso-trägrund is specially developed for indoor use and can be applied to a wide range of wood elements:
- Doors and door frames
- Windows and window sills
- Panels and mouldings
- Wood furniture
- Frames and other wood details
The product is particularly suitable for raw wood or wood that tends to yellow discolouration or bleed-through of natural wood substances.
Benefits of the Product
The primary strength of this primer lies in its blocking properties. By functioning as an effective barrier, it minimises the risk of water-soluble dyes and resin from the wood bleeding through and spoiling the final finish.
Good adhesion ensures that the primer bonds solidly to the wood surface and creates a stable foundation for the topcoat. This is essential for a professional and durable result.
The blocking function makes this product an essential tool for painters and DIY enthusiasts who want to avoid bleed-through and discolouration in their woodwork.
Practical Considerations
It is important to note that this blocking wood primer cannot be tinted and is supplied only in standard white. This ensures consistent results and optimal performance of the blocking properties.
Caparol, a recognised manufacturer of quality paint, has developed this product to meet professional standards for both tradespeople and private consumers who prioritise quality and durability in their painting work.
