The fabric sealer improves colour fastness during washing and extends the life of wax-printed garments. 2-3 hours drying time

You can use this fabric sealer on the material you'd like to print wax onto. It will help retain stronger colours in the wax when the items are washed.

Use a natural fibre material like cotton for best results because it absorbs and retains the wax better than artificial materials – a reasonably good quality tee-shirt fabric.

Apply fabric sealer on the back of the area of your material where you intend to print your wax image and allow it to dry.

You could create and print the wax image onto the front of your fabric material above over the sealed area (after the fabric sealer has dried)?

You can apply a coating of fabric sealer over the front surface of the printed wax image and allow it to dry.

Only wash at 40C cycle. The seal will remain stiffer than the surrounding natural fabric. Still, the colours will be much better retained than without sealer (as long as you follow the application method described above).
