Increase Adhesion & Strength Of M-Sand / Cement Mortar Mixes

Tremendous adherence to a variety of substrates

Provides Greater Flexural Strength

Increases Impact Resistance

Increases Resistance to Abrasion

Longer Lasting than Unmodified Concrete

Product Description

Venlac Safe Cement Modifier is a specially designed product that increases the adhesion and strength of M-Sand/Cement mortar mixes. It will cause them to hold tenaciously to old concrete, brick, and other substrates. At the same time the flexural, impact, and compressive strengths are more than doubled. These are manufactured from high grade quality material by employing highly advanced methodologies by our experts.


New masonry surfaces must be allowed to cure completely. Recommended curing time is 28 days minimum. A base coat of   Venlac Safe Cement Modifier is recommended for best performance.

Cementatious formulations modified with cement modifier show improved compressive, abrasive, flexural, bonding and water resistance properties. Modified mortars have excellent adhesion to a variety of substrates including concrete, brick, metals, insulating foams, and wood.

Modified mortars containing these modifiers are stable to ultraviolet light and resist discoloration due to sunlight exposure. Application of masonry as thin as 1/8 inch or less can be made effectively.


These products may be used as an aid in bonding new masonry material to old and as an effective additive for mixing with new masonry for improved performance properties.

A) Use these products as a bond aid when applying new masonry to old by saturating the existing surface with mixture. Apply new masonry while bonding aid still wet (damp). If drying occurs, simply re-coat and apply new masonry while second coat is still wet. Coat an area no larger than can be covered with new masonry (usually within 10 to 15 minutes). See product label for dilution recommendations.

B) Use full strength when adding to cementatious formulations at the rate of approximately 1 gallon pre 40 lbs. Portland cement. In determining the appropriate amount to be used, do not consider the weight of sand, gravel, or other filler material contained in ready for use materials such as sand or mortar mixes. Additional water, if needed, may be added to the mixture until the desired consistency is achieved, or additional product may be used to increase performance characteristics.

Handling & Storage

Keep containers airtight during handling and storage to avoid loss of material. Store venlac safe cement modifier in a cool dry place and also protect it from extreme climatic conditions during storage, in transit and at site.


It is not advisable to use any waterproofing chemical as base, top coat or additive. Over dilution of venlac safe cement modifier may result in shade variation, poor hiding, poor bonding or flaking. Excessive brushing and stretching are also to be avoided. No thinner or universal stainer is to be used with cement modifier.

Safety Measures

Kindly refer to the MSDS for Cement Modifier which gives detailed information on safety measures while handling the paint, which is available on request.

Store the container with the lid tightly closed in an upright position, in a cool, dry place.

Keep out of reach of children and away from eatables.

May be harmful if swallowed. In case of ingestion seek immediate medical attention. In case of skin contact immediately wash skin with soap and plenty of water. Get medical attention if irritation develops or persists.

Wear eye protection during application. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Do not breathe vapour or spray. It is recommended to wear suitable nose pad during sanding and surface preparation to avoid dust inhalation.

Do not pour leftover paint down the drain or in water courses.

In the event of spills, contain spillage using sand or earth.
