Refractory mortar for applications exposed to high temperatures.
BEYEM REFRAC is a refractory mortar formulated based on aluminous cement, refractory aggregates of selected granulometry and special additives that give the mortar great plasticity and workability. Especially suitable for placing refractory bricks and plasters in high temperature environments.
Ideal for barbecues, fireplaces, wood ovens and stoves for domestic use.
High thermal resistance.
High mechanical resistance.
Easy to apply.
Resistant up to 1000ºC.
Indoor and outdoor use.
Assembly of refractory bricks, terracotta... subjected to high temperatures (Up to 1000 °C). Lifting of chimneys, barbecues, ovens, etc... It can also be used to cover walls in contact with high temperatures or fire.
The useful supports for the application of BEYEM REFRAC are:
Refractory bricks, terracotta for refractory applications, etc…
Other supports in contact with high temperatures and/or fire consult the manufacturer's technical department.
The previously indicated supports must be healthy, clean, free of traces of paint, poorly adhered parts or substances that may hinder adhesion. All supports must have adequate flatness. The support must not have clear humidity problems and, where appropriate, it must have completed its curing shrinkage, having respected its maturation period. In case of heat, wind or on highly absorbent supports, it is advisable to moisten the support and wait for the water film to disappear. Do not apply on plaster or paint.
Mix BEYEM REFRAC with 4.0-5.5 liters of clean water per 25 kg bag manually or with an electric mixer until a homogeneous, creamy and lump-free mixture is obtained. Let stand 5 minutes before application. Spread the dough on the support or piece with the help of a palette. Place the piece on the layer of fresh mortar and press hard. Level with the same trowel or submerge and smooth with a rubber band.
The remains of the product that have begun to harden should not be mixed with more water, since this causes a decrease in the properties of the mortar.
Do not apply below 5ºC or above 30ºC.
Do not apply with risk of frost, rain, strong winds or direct sun.
Respect the proportion of water indicated in each mix.
In extreme weather conditions (a lot of wind at high temperatures) drying occurs faster than normal. It is recommended to water the product by gentle sprinkling the day after its application.
Commissioning must be carried out 7 days after assembly, heating up gradually.
