Waterproof Basement Walls From The Inside

When Waterproofing basement walls from the inside it is important to first try to eliminate the source of the water problem on the outside. This is done by checking the following:
1. Make sure gutters and downspouts are not spilling over and are running out away from the foundation. Cleaning gutters and making sure downspouts are not emptying near foundation are key factors. Extensions on downspouts will get the water away from the foundation.
2. Make sure the grading of the land does not puddle water near foundation. This is easier said than done and will require alot of hard work or expensive excavation.
3. Make sure all cracks are patched and sealed along with any    uncoated exposed concrete. For this use Hydro-Seal 75 epoxy coating for the sealing of the concrete, and Hydro-Epoxy mortar(Hydro-Seal 75 mixed with Cement & Sand) for filling the cracks. A wide putty knife works best for this.
Exterior:Skim over cracks with Hydro-Seal 75 epoxy Mortar as smooth as possible
Apply Hydro-Seal 75 over all exposed concrete; A two coat application over all exposed concrete is required.
Interior: (After proper preparation) Apply two coats of Hydro-Seal 75 to areas where moisture, dampness and seepage occur to walls and floor perimeter.Patch cracks and holes with Hydro-Epoxy Mortar. For a uniform appearance of basement walls and floors coat entire basement with Hydro-Seal 75.

Hydro-Seal 75 is an odorless water based epoxy available with or without an anti-microbial addative. Hydro-Seal 75 is mixed at a 1 to 1 ratio prior to paint roller or brush application. A 30 minute pot life allows you to mix 1 gallon at a time before paint on applications. No special tools or protection is required. All you will need is a mixing bucket, mixing sticks, a paint brush and a 3/8" or 1/2" nap roller and a paint tray.
1.Just mix your gallon(Hydro-Seal 75 is available in 1 gallon kits) and apply like paint to basement walls, exterior basement walls & basement floors.  Shake cans & stir before mixing
2.Allow 2 to 4 hours to dry before applying 2nd coat.  Floors may erequire 6 to 8 hours before re-coating
