Everbuild Wood Filler Hardener / Catalyst - 40g

This is a catalyst or hardener paste used to initiate the curing process for two-part styrene-based wood fillers.

It is designed for use with most common two-part styrene-based wood filler systems. Always check the instructions of your specific wood filler product for compatibility.

The shelf life is 24 months from the date of manufacture, provided it is stored correctly.

Store in cool, dry conditions away from direct sunlight, ideally between 5°C and 20°C, in its original container and out of reach of children.

The typical ratio is 10 parts wood filler to 1 part catalyst by volume, but you must refer to the instructions provided with your specific wood filler for the exact ratio.

If not enough catalyst is used, the wood filler will not harden properly, or it may remain soft and sticky, compromising the repair.

The working time varies depending on the specific wood filler and ambient temperature. Refer to the wood filler's instructions, but generally, you should expect only a few minutes to mix and apply.

Ensure the correct ratio of catalyst to filler was used. Re-check the mixing ratio specified by the wood filler manufacturer. Also, verify that the catalyst is not past its shelf life and has been stored correctly.

This can sometimes occur with specific filler types or warmer ambient temperatures. Ensure you are not exceeding the recommended amount of catalyst and try to work in a cooler environment. Prepare only the amount of filler you can use within its working time.

This typically indicates insufficient or uneven mixing. Ensure the catalyst is thoroughly and uniformly mixed into the filler until a consistent color is achieved before application.
