KoverTek TekPur SD (Same Day) Primer is a fast-curing single component polyurethane-based primer suitable for almost all substrates, applicable to porous and non-porous surfaces. Due to the increased speed of cure, it can be overcoated on the same day and is ideal for use in colder conditions. TekPur SD can also be used on both dry and wet concrete; when the concrete is classed as ‘Green’ TekPur SD can also be used as a low-cost solution for sealing the substrate.

Features & Benefits

• Single component
• Fast curing
• Low viscosity
• Easy to apply, even to difficult substrates such as wet concrete
• Excellent wettin out and impregnation properties
• Elastic, with fast paint-over times

Preparation & Application

The area to be treated should be first cleaned with a high-pressure washer or a stiff bristled broom and soapy water to remove grease, oil, wax or any other surface contaminants and loose particles. Any defects in the surface such as cracks, splits and blisters need to be treated prior to application, surfaces that are irregular should be filled with a suitable material. Allow all surfaces to dry before commencing work.

Gaps in the substrate/surface above 2mm or subject to movement needs to be filled with Soudal Fix-All or similar product (do not use silicones) If applying onto OSB3 boards the joints need to be taped with TekTape self-adhesive butyl tape, tape should be applied centrally to joints.

Apply TekPur SD with a brush or short pile roller. The product has a working time of 60 minutes.

NB – Cure times are based on an average of 20°c and will be shorter at higher temperatures and conversely slower below 20°c.

Suitable Substrates

*Recommended surfaces for priming:

PLEASE NOTE – There are many variations of the surfaces listed as suitable, however care much be taken in testing a small area prior to commencing the main body of work to ensure that a suitable bond is achieved, we do not recommend for use on areas over 200m² in one continuous area. Please contact the Technical Team to discuss larger projects.

NB: When applying to any surface a primer must be used prior to application and when applying to Single ply or Plastisol surfaces then TekPrime PVC must be used instead of the stand TekPrime SD (same day primer).

Not suitable for unsound surfaces, swimming pools in contact with chemically treated water, fishponds.

Safety

The resin should be stored indoors in original, unopened, undamaged containers in a dry place at storage temperature between 5 - 25°C. Exposure to direct sunlight should be avoided. Once opened the product needs to be used as soon as possible.

It is of extreme importance that protective gloves and eye protection are worn when handling or mixing product. Spills or splashes must be removed immediately – if allowed to dry, material can only be removed mechanically or with heat and/or harsh chemicals.

Contains Flammable & Volatile solvents – Always apply in well-ventilated area, no smoking or naked flames can be near the application area whilst the product is curing. Solvent fumes are heavier than air and need to be ventilated correctly if using in enclosed areas and suitable active carbon filter masks must be worn.
