Sherwin-Williams Sher-Cryl M770


Sherwin-Williams Sher-Cryl M770 (formerly known as Envirogard M770) is a water based quick drying gloss finish or sealercoat for the entire Sherwin-Williams FX product range

VAT excluded

£94.56 Tax incl.


Sherwin-Williams Sher-Cryl M770 is used in areas where solvent emissions are not desirable. It may also be used as an essential decorative sealer-coat for the FX product range to provide resistance to moisture. 


BS476 Part 7 Surface Spread of Flame Material - for details of substrate/scheme, consult our Technical Team. 

Recommended Topcoats

Indefinitely self-overcoatable. For details of overcoating with other materials, consult Rawlins Paints. 

Additional Notes

In common with other water based materials, drying of this material is retarded by high humidity conditions. Lack of air movement also slows down the process, and under such conditions it is advisable to introduce some method of circulating air over the coated surface to speed up the drying.

An air speed of 2 metres per second is recommended. When used as a sealer-coat over the FX product range, a slight reduction in final gloss level will be observed. This does not detract from exposure performance, nor fire resistance properties.

Certain shades, for example reds and yellows, may require additional coats to achieve full opacity.

Numerical values quoted for physical data may vary slightly from batch to batch.
