Best used on concrete floors with a low moisture content (less than 4%)
If you are experiencing some dampness or light moisture it is best to use the Lithi-Tek 4500 primer followed by the Iso-Tek 8540VOC. The Lithi-Tek 4500 is a penetrating concrete densifier designed to fill in the smallest pores and voids in the concrete with CSH (calcium silicate hydrate, a byproduct of cement hydration.) Five to seven days after the Lithi-Tek 4500 has been used the Iso-Tek 8540VOC can then be applied. The Iso-Tek 8540VOC is a 55% actives solvent based, VOC compliant silane that will impregnate the concrete making it water repellent.
Lithi-Tek 4500 is concentrated and needs to be mixed with distilled water prior to application. One part Lithi-Tek 4500 is mixed with 3 parts water. One coat is applied with either a sprayer or roller.
Iso-Tek 8540VOC is ready to use and can be applied with a solvent resistant sprayer or roller. Two coats are applied wet-on-wet (the second coat is applied immediately after the first coat while the first coat is still wet). If the Iso-Tek 8540VOC is not within your budget the Siloxa-Tek 8500 may be used as a sealer after the Lithi-Tek 4500 primer.
Best used on concrete floors with a high moisture content (up to 20lbs/24hr/1000ft) or prior to installing wood, carpet, tile or epoxy flooring
If the concrete basement floor has a high moisture content the Vapor-Tek 440 is the product to use. This two-component epoxy coating is designed to reduce moisture vapor emission rates of up to 20lb/24hr/1000ft. If you are going to be installing carpet, tile or wood this is the product to use to prevent any moisture from traveling and dis-bonding the flooring. It is also an excellent choice to use the Vapor-Tek 440 as a primer before installing an epoxy floor.
Each gallon will cover up to 100 square feet at 17 mils thickness and will leave a clear, gloss finish. Part A is mixed with Part B prior to application and installed with an epoxy glide roller. The Vapor-Tek 440 will stop dusting, can be applied to concrete as little as 10 days old and only requires one coat.
The Vapor-Tek 440 does have a short pot life which means once Part A and Part B are mixed together it needs to be applied within 30-40 minutes. Once the pot life has been reached the product can no longer be applied. The Vapor-Tek 440 is dry and ready for foot traffic within 24 hours and fully cured in 3-7 days.
Best used preventatively on concrete floors without any moisture
The Lithi-Tek 9500 is best used on new concrete or used preventatively on concrete that has never had any moisture issues. Lithi-Tek 9500 is concentrated and needs to be mixed with distilled water prior to application. One part Lithi-Tek 9500 is mixed with 4 parts water. Two coats are applied wet-on-wet (the second coat is applied immediately after the first coat) with either a sprayer or roller.
