PRODUCT INFORMATION & RESOURCES

Description:

Cemix® Cemplus is a very active non-staining liquid which readily mixes with water to improve the workability and adhesion of cement mortar and plaster. This product eliminates the need for hydrated lime, but can be used with lime if required. A great masonry aid for laying bricks, concrete blocks and stone. Absolutely essential for solid plastering.

Typical Application / Uses:

To improve the workability and adhesion of cement mortar and plaster. Eliminates the need for hydrated lime, but can be used with lime if required.

Advantages:

  • Greater plasticity.
  • Increases bond strength.
  • Quicker application.
  • Easier workability.
  • Cleaner work, less droppings.
  • Easier ruling off.
  • Reduces cracks and crazing.
  • Cuts costs – increases productivity.
  • Eliminates need for lime.
  • Reduces water absorption.
  • Resists freeze – thaw damage.
  • Economical – fraction of the price of plasticising paste.
  • Helps prevent efflorescence

Substrate Preparation:

It is important to ensure the substrate surface is clean and free from dust and loose material. Old paint should be removed, as should oil, grease, wax, curing compounds and surface laitance etc. Substrate surfaces should be pre dampened with water, with any excess brushed off.

Mixing:

Slurry Coat:A typical mix design for floor topping or patch repairing is 1 cement, 2 – 3 clean dry sand with Cemix® Acrylbond, at the rate of 5L / 40kg bag of cement, added to the mixing water. For more difficult situations, such as permanent dampness, very dense floors etc. a slurry coat of the dry mix with a 1:1 mixture of Cemix® Acrylbond and water, added to give a brushable slurry, should be applied firmly onto the surface with a brush or stiff broom and allowed to achieve initial set before the topping, mortar etc. is applied.

Application:

In all applications it is important to ensure that the substrate surface is clean and free from dust and loose material. Old paint should be removed, as should oil, grease, wax, curing compounds and surface laitance etc. A primer coat will ensure maximum adhesion. The surface should be pre dampened with water, with any excess brushed off. Scrub undiluted Acrylbond into the surface avoiding puddling. The mortar, topping, plaster should be applied while the primer is still tacky for optimum results.

Curing:

As with all concrete repair, new repairs should be protected from wind, rain or direct sunlight using wet hessian or plastic sheeting until cured

Materials:

  • It is important to use clean, washed and graded silica sand for Cemix® Acrylbond modified mortars.
  • Cement should always be fresh and dry.
  • All expansion joints and shrinkage control joints are to be reflected through the new repair mortar. Failure to follow these joints through could lead to cracking and subsequent failure.

Technical Data:

  • Appearance – Milky White
  • Application Temp –5oC – 30oC
  • Yield / Coverage – 12m2 – 16m2 per litre. Coverage is dependent on the roughness and porosity of the existing surface.

Limitations:

Cemix® Acrylbond is not to be used in areas subject to constant immersion.

Agitation:

It is important to agitate this product well before use.

Storage:

Cemix® Acrylbond has a shelf life of 12 months minimum when unopened in original containers.

Cleaning:

Clean all tools with water & brush immediately after use.

Precaution:

The mortar, topping, plaster should be applied while the primer is still tacky for optimum results.
