Since PosiSeal PS#1 is a deep-penetrating sealer, the surface it is to be applied to must be clean and porous enough to allow penetration into the substrate. 1是一种高渗透性混凝土密封剂，其待处理表面必须保持清洁，并具有多孔性，以利于密封剂的渗透。
PosiSeal PS#3, because it penetrates the surface and chemi cally bonds, will last for an extended period of time. 因其表面渗透性和化学亲和性，而使其功效更加持久。
POSISEAL PS#1 allows entrapped water vapors to escape because the vapor molecule is significantly smaller. 1允许蒸汽分子的溢出，因为蒸汽分子十分细小。
PosiSeal PS#3 is a colorless, odorless solution of specialized reactive chemicals that penetrate concrete surfaces to seal, densify and harden the material. 3是无色无味的专业化学药剂.;通过对混凝土表面的渗透;可以起到密封;密实;以及强化混凝土的功效
PosiSeal PS#3 has a combination of water-based safety, ease of use and long term performance that make it an attractive alternative to currently available sealer-type products. 3是水溶性;易用性;以及长效性的集大成者.;是正在使用的混凝土密封产品的有效替代者
POSISEAL PS#1 allows entrapped water vapors to escape because the vapor molecule is significantly smaller. This vapor transmission is necessary if the substrate is to survive many freeze/thaw cycles. 1允许蒸汽分子的溢出，因为蒸汽分子十分细小。如果混凝土处于冻融环境中，则蒸汽分子的溢出非常必要。
POSISEAL PS#2 allows a calculated 2% vapor transmission rate necessary for concrete to breathe. This vapor transmission is necessary for the substrate to survive many freeze/thaw cycles. 2允许大约2%25的蒸汽分子的溢出，以满足混凝土的呼吸要求。这种蒸汽分子的溢出对于处于冻融环境中的混凝土非常重要。
