About Peneseal FH

Peneseal FH

How it works


Pores and capillaries in the untreated concrete are subject to penetration by moisture, oils, acids, etc. and allow release of concrete dust.


Peneseal FH penetrates into the concrete surface where it reacts with the free lime and alkali to form a solid mass that locks the pores and capillaries in the concrete, permanently sealing the concrete.

Peneseal FH Concentrate PDS
PENESEAL FH™ is a clear, reactive penetrating sealer for concrete and masonry building materials designed to permanently protect, preserve and trengthen them. PENESEAL FH™ penetrates deep into concrete and reacts with the elemental concrete ingredients to solidify them into a harder, denser, stronger concrete mass. Alkali salts and minerals are flushed out in the process, eliminating efflorescence and leaching and increasing bonding of surface coatings.
