RadonSeal Plus Outdoor/Indoor Concrete Deep Penetrating Protectant Sealer, Reduces Moisture, Strengthens, & Reduces Radon Gas Levels, 5 Gallon Bucket

Old concrete requires a little extra care when maintaining. Get the job done right with the RadonSeal Plus Clear Protectant Concrete Sealer. Specially concentrated for older, more porous concrete, this material will seal up your old foundations, pads, and heavyweight concrete blocks. This unique sealer will protect your indoor and outdoor concrete against dusting, cracking, freeze-thaw, deicing chemicals, and efflorescence without changing its appearance. Concentrated for older concrete, RadonSeal Plus is recommended for indoor concrete poured up to 20 years ago or outdoor concrete over 2 years old. The RadonSeal Plus works by absorbing deep into the concrete and sealing pores and capillaries below the surface. Unlike other sealants, this concrete sealer will not leave behind a glossy coating and won't cause the surface to become slippery. This factor makes the concrete sealer a great choice for areas your loved ones frequently walk on every day. Whether you're renovating your basement or hardening an aging sidewalk, RadonSeal Plus will help you craft a firm foundation the first time around.
