Tordeck DSP

Tordeck DSP is a super-high solids two pack epoxy resin based primer used for the suppression of vapour pressure effects to prevent air/moisture blistering on suspect concrete and asphalt balcony surfaces, suspended decking etc, prior to application of Tordeck two pack systems. Also used in conjunction with Florex Solvent Free Floor Coating.

Surface Preparation

Ensure surfaces are sound, clean, contaminant-free and as dry as possible before coating. Thoroughly scrub down all dirty surfaces with alkaline detergent solution followed by thorough rinsing (alternatively steam clean) and dry off. Remove residual contamination by scraping, surface grinding etc. Mechanically remove any unsound/incompatible coatings. Fully grind or vacu blast bare concrete to give an open sandpaper like surface. Reduce undulations/peaks etc by mechanical abrasion or grinding.

Application

Apply one or two coats as required by roller or squeegee to give an even spread, ensuring good cover on profile peaks etc. Discharge mixed material as soon as possible to maintain workability. Spike roller if necessary to de-aerate coating.

Limitations

• Do not apply to inadequately prepared or unsound surfaces.
• Do not apply at surface temperatures below 8°C or overnight ambient temperatures below 5°C. Low overnight temperatures will further extend minimum overcoating times.
• Overcoating should be carried out within the timescales stated on the product data sheet to promote maximum intercoat adhesion and avoid film defects. Ensure surfaces are clean between coats.
• Substrates with relative humidity of greater than 85% will require two coats of Tordeck DSP.
