Fast service

Recieved my wet look patio seal before the stated arrival date. Die to weather I've been unable to make use of the product yet so can't give a review in that respect. However the overall purchase and delivery was excellent

Poor usage information

The product itself seems very good and so far im very pleased with it but the usage information is poor. Although the packaging indicates how to use (roller, brush etc) and that it is re-coatable until the desired finish is achieved it does not give a re-coat time estimate or tell how to clean equipment after use eg is it water soluble so equipment can be washed or does one need to use a solvent eg white spirit ? Not all of us are professionals or highly experienced DIYers and such information is really needed
