Applying a DPM is sometimes necessary if there is too much moisture in the subfloor and waiting is not an option. You can also opt for extra security and wait for the subfloor to dry naturally. In today’s quick moving environment, this is the less likely option. With the WAKOL MS330 Silane Primer the waiting time is reduced to a minimum. You have a moisture barrier in just 1 layer and within 1 hour. As the product is completely free of epoxy and isocyanates it is also a cleaner choice for your project.
