As a moisture barrier against increased humidity in unheated cementitious substrates
Protection of the calcium sulphate screed against moisture

Solvent-free, acrylic based, sanitizing moisture barrier, primer and a bonding agent with a high bond strength. For absorbent and non-absorbent substrates to use before levelling, waterproofing, thin-bed tile installation or the installation of textile/flexible floor surfaces and parquet/engineered wood flooring, large, and small format tiles. Okatmos® DSG can be used as a moisture mitigation system on cementitious substrates such as cement screeds or concrete barrier against excessive moisture.

Residual moisture of up to (85% RH) for unheated cement screed (2-layer application) and 4 CM-% (90% RH) (3-layer application).
For unheated concrete substrates (also under cement composite screed) with a maximum residual moisture of (90% RH) (2 layers) and (95% RH) (3 layers) according to DARR method measurements.
For use under large ceramic tiles to provide moisture barrier from self-levelling compounds or normal-set thin-bed mortars.
No thickness limitation when using Kiesel self-levelling compounds over 2-layered applications on calcium sulphate screeds.

Okatmos® DSG is also a suitable primer and bonding agent for smooth, dense and non-absorbent substrates such as, e.g. old tile, natural stone or artificial stone surfaces before levelling work or thin-bed tile installations. Okatmos® DSG can also be applied over properly prepared cut-back adhesive, old or badly sanded asphalt floors, terrazzo, tile, particle board, chipboard, OSB, cement backer units, and concrete screeds and well bonded ceramic tiles. When used over existing exterior tiles a waterproofing membrane Servoflex DMS 1K Plus SuperTec is required. Metal and similar substrates must be rust-free and cleaned with Acetone. Odorless and environmentally friendly. As part of the Okatmos®-product-line, Okatmos® DSG avoids the development of odors originating in microbial interactions in the floor structure. It is therefore very suitable for renovation purposes.
Not suitable over liquid sulphate adhesives, magnesia- based screeds and Stonewood-screeds. Sanitizing properties provide an additional odor containing properties. Okatmos® DSG does not replace necessary or required waterproofing membranes.

The substrate must be dry, clean and sound. Remove mechanically any oil based or loose products. The existing substrates must also comply with the applicable local and national standards and regulations in each case. The respective substrate must be tested in accordance with the applicable standards and when in doubt contact Kiesel technical department. Follow additional guidelines located in TTMAC and TCNA manuals.

Shake container before use.

Okatmos ®DSG as a moisture barrier:
Okatmos® DSG is applied as a two or three coat system to wooden substrates and non-absorbent substrates undiluted with a lambskin roller, high quality paint roller or brush on the substrate. On absorbent substrates, Okatmos® DSG is diluted 1 : 1 with water for the first application. After drying, a second or third application is undiluted to obtain a proper moisture barrier based on the required reduction of RH value. The third coat is applied when the second one is completely dry. Allow the applied primer to dry thoroughly.
Apply Okatmos® DSG to the substrate with the Kiesel Primer or similar evenly over the entire surface and filling the pores. Avoid pooling. Not to be used over hydronic radiant floor heating as a moisture barrier. Can be used over electric heated floors.
Allow the primer to dry thoroughly after applying each coat. Not to be used over magnesium oxide, xylolite flooring, sulphate lye.

As a primer bonding agent:
Okatmos® DSG can also be applied over well prepared cutback adhesive, old terrazzo, particle board, chipboard, OSB, cement backer units and concrete screeds and well bonded ceramic tiles. When used over existing exterior tiles a waterproofing membrane Servoflex DMS 1K Plus SuperTec is required. Metal and similar substrates must be rust-free and cleaned with Acetone.
