Torcure MC Binder/Sealer

We no longer stock this product, but can recommend Tor Elastaseal Z Binder Sealer as a great alternative.

Torcure MC Binder/Sealer (PU885) is a single component, moisture curing polyurethane resin solution for use as a stabilising sealer and primer for use on a wide range of substrates such as concrete, asphalt, bitumen, felt, asbestos, plaster, render, etc.

Preparation

All surfaces to be treated should be clean, sound, dry (preferably less than 5.5 on the Protimeter concrete moisture scale), sound and free from laitence, dirt, dust and other contaminants (note: deeply contaminated substrates may require special treatment). Rake out loose and friable materials and make good with a suitable proprietary filler or repair compound. Bare concrete surfaces should be suitably prepared (e.g. abrasive blast, disc grinding, scabbling, sanding, etc.) to give a clean, open textured surface. All previously coated areas should be carefully inspected. Where necessary, any residual coatings should be completely removed to promote good substrate adhesion. Any firmly adhering coatings must be inspected and application tests carried out to verify proposed system adhesion. If adhesion is unsatisfactory complete removal of coatings may be required unless an alternative spot primer can be used. Treat any areas of moss or fungal attack with Torkill W Fungicidal Solution (DM405).

Application

Brush, roller or airless spray. Two coats may be necessary on highly porous substrates.

Limitations

• Overcoating must be carried out within the timescale stated otherwise it may be necessary to solvent wash or abrade the first coat in order to obtain system adhesion.
• Take out a working quantity from the tin and re-seal immediately to prevent moisture contamination in the can.
• When airless spraying operatives must wear self contained breathing apparatus (contains isocyanates)
