PREMTARD TF is a blue aqueous liquid which is designed to be spray applied to the top face of cast concrete to retard the cure of the concrete on the top surface. This will produce an exposed aggregate finish which will give an adequate mechanical key between concrete pours.
PREMTARDE TF should be applied to concrete in construction joints or to the top face of concrete slabs to provide a good mechanical key for the application coatings or screeds or for subsequent concrete pours.
• Easy spray application onto fresh concrete.
• Uniform depth of retardation.
• Water based environmentally friendly product.
• Alleviates the need for mechanical scabbling.
