AD-FLEX
Product description
Rubber latex based on elastomeric polymer in water dispersion, to be used as an elasticising admixture for cement and mortar as a substitute for mixing water.
It imparts exceptional elasticity, adhesive power and impermeability to mortars.
Suitable for internal and external substrates, cement and cement adhesives, making them suitable for demanding applications.
Product use
Elasticising additive for cement and mortars in general, to improve their adhesion, elasticity, water impermeability and
final performance.
Adhesive latex additive for cement mortars is particularly suitable for laying large formats, outdoor laying, ceramic swimming pool coverings, coverings subject to high mechanical or hygrothermal stress.
Additive for cementitious mortars such as screeds, plasters, skim coats, in order to improve their elasticity and adhesion characteristics.
Preparation of adhesive grouts for anchoring new Portland cement-based screeds on old substrates.
Substrates
The substrates to be treated must be consistent and free of surface dust, release agents and anything else that could jeopardise good adhesion.
Crumbling or already detached parts must be removed mechanically.
Applications
Additive for cement adhesives
Pour the right amount of liquid into a clean container and slowly add the powder, mixing with an electric drill fitted with a mixing paddle until a homogeneous, lump-free mixture is obtained. Let the mixture rest for at least 5 minutes and stir briefly for a few seconds. The resulting dough can be worked for about 6 hours.
If no special performance is required, but only improved elasticity is desired, up to 50% clean water can be added to AD-FLEX before mixing with the powder.
Anchoring slurry for anchored screeds
Add one part AD-FLEX to one part water.
Mix cement with this mixture until a liquid, homogeneous slurry is obtained and spread the mixture on the surface to be treated.
In order to achieve optimal adhesion, pour ‘fresh on fresh’.Kromax additive products
Laying warnings
Damp substrates with the presence of efflorescence must be previously treated with dehumidifying systems.
Do not use on magnesic substrates.
When preparing mixes, first mix AD-FLEX with water and then dose the other components in powder form, observing the quantities indicated.
For outdoor use, avoid application in conditions of imminent rain, frost, strong wind, beating sun and high temperatures.
Application temperature
+8°C / +35°C
Important
Always carry out a pre-application test in order to check the compatibility and actual yield of the product as it varies depending on the substrate.
