Overview

PENESEAL™ FH is a clear, reactive penetrating sealer for concrete and masonry building materials designed to permanently protect, preserve and strengthen 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.

Applications

Any cementitious based substrate such as, but not limited to: concrete, terrazzo, heavyweight concrete block, plaster, stucco or mortar.

  • Warehouses
  • Hangars
  • Distribution and storage facilities
  • Food processing plants
  • Manufacturing facilities
  • Any type of facility with exposed concrete flooring

Advantages

  • Curing: allows concrete to cure uniformly through its chemical and moisture retention reaction. This aids in a more complete hydration process and reduces hairline and temperature cracking.
  • Sealing: penetrates deep into the concrete, which allows its chemical reaction to lock the pores from within, providing an integral and permanent seal.
  • Hardening: binds the elemental parts of the concrete, solidifying them into a denser, tougher, harder mass. This results in a more durable concrete with higher surface abrasion resistance and compressive strength.
  • Dustproofing: densifies the surface of the concrete through its chemical bonding and flushing of the weaker concrete salts and minerals. This permanently seals the surface and eliminates surface dusting.
  • Protection from efflorescence and leaching: penetrates deeply into concrete, neutralizing the alkali salts and minerals that cause efflorescence and salt leaching. These weakening salts and minerals are forced to the surface and flushed away during the application process.
  • Improved bonding: eliminates the alkali salts and minerals that weaken and delaminate surface coatings, which improves bonding of any type of covering.
  • Nontoxic: PENESEAL™ FH is nontoxic and is not harmful to lungs or hands. Complies with all VOC and USDA regulations.

Technical data

  • Abrasion: ASTM C779, 80.9% increase in abrasion resistance.
  • Bonding: ASTM D3359, 60% increase in epoxy adhesion. 50% increase in polyurethane adhesion.
  • Curing: 61% greater moisture retention during the initial critical 24 hour curing period, as compared to untreated samples.
  • Hardening: ASTM C39, 40% increase in compressive strength 7 days; 38% increase at 28 days over untreated samples. ASTM C805 (Schmidt hammer), 16.1% increase in impact resistance.
  • Permeability: approximately 98% reduction in permeability at 100 psi.
  • Coverage: approximately 5 m²/L (200 sq ft per gallon) of diluted concentrate. Coverage can vary depending on the temperature and porosity of the concrete.

Test results obtained under controlled laboratory conditions at 23°C (73°F) and 50% relative humidity unless otherwise specified. Reasonable variations can be expected due to atmospheric and job site conditions.

Mixing

PRIOR TO USE, agitate bucket or drum and thoroughly mix PENESEAL™ FH with clean water in equal parts by volume.

Special considerations

  • Do not use PENESEAL™ FH on extremely porous masonry, such as lightweight block.
  • Do not apply PENESEAL™ FH to frozen or freezing surfaces or when temperature falls below 4ºC (40ºF) or if temperatures will drop below freezing during the curing period (approximately 24 hours).
  • Prevent PENESEAL™ FH from getting on glazed and finished surfaces such as glass, aluminum, etc. In case of contact, flush immediately with water.
  • Protect surfaces from equipment leaks or other leaks, such as oil, hydraulic fluid, etc.
  • PENESEAL™ FH treated surfaces can become slippery during application. Exercise caution and wear appropriate footwear and protective clothing.
  • PENESEAL™ FH is not a vapor barrier.
  • Apply to colored concrete only after the slab is fully cured.
