There is no mosaics cement in our country..... Advice me please
it is possible to add it .
(A)For outdoor work the ideal adhesive to use is cement based. Either a cement based tile adhesive or a sand and cement mix. Of course the tile adhesive MUST be both water-proof and frost-proof. Cement base adhesives can be bought in bags from 2kg up to 22kg. They must be mixed to a firm consistency and applied to a dry surface. Your mosaic tiles are then pressed into the mortar to give a good contact. Work with a small amount at a time as you will normally have about 20 minutes working times with each batch. To help improve the flexibility and adhesive properties of the mortar add a plasticizer or polymer additive to the mix one part additive to two parts water. This is the preferred mix if you are making a mosaic for a predominantly wet location. Add this to the cement until the required consistency is reach. If using sand and cement mix use the ratio 3 or 4 parts fine sand to 1 part Portland cement. Mix thoroughly and add water. Mix to the required consistency. It is advisable to wear gloves whenever you are dealing with cement based products. To improve the adhesive and strength properties of the mortar, the setting time should ideally be long and slow. So if you can cover each days work with a polythene sheet to protect the work and help the setting.
