Applied product ready for use

For standard porous concrete applications, Sikalastic® PU Primer is ready for use from the pail. For substrates less porous, addition of up to 10% xylene can be added to assist in penetration of Sikalastic® PU Primer into the substrate. If in doubt, a site trial and adhesion test should be undertaken.
