Start by adding a very small amount of Liquithick to your color/medium
Mix well with a palette knife, adding more (up to 25% maximum) until you get desired consistency
Once applied, leave to dry for five to seven days for maximum strength and flexibility
As this is an additive – with no acrylic binders - do not add more than 25% to your color/medium and do not mix with other additives. This can cause excessive shrinkage, cracking and the acrylic film to break down
