As with our tried and tested INSTAMAK Reparaturasphalte we supply Repair asphalt PA as a 1-component, ready-to-use mix, packed in practical 25kg tubs.
Drying or priming of the repair area is not required.
High quality aggregate blends in acc. to EN 13043 as well as a mixture of bitumen, polymers, our special adhesives and additives guarantee for a permanent repair even when raining or wet.
With INSTAMAK PA you can repair small damages quickly and cost-effectively without blocking the drainage function of the surface. The porosity is – depending on grade size – between 25 – 26,5 Vol-%. INSTAMAK PA is available in grade 0/8, 0/11 and 0/16 mm.

When using normal asphalts for small repairs to PA surfaces the drain and diffusion capability is hindered.
![Opa Asphalt Drainage](https://www.instamak.de/wp-content/uploads/2016/05/2_PA-Asphalt-2.png)
This results in stagnant moisture and ice beside and under the repair areas which often causes not only flaking of the repair but also damage to the surrounding area.

Solution:
INSTAMAK PA ensures good drainage and the surface remains open for diffusion.
