Revinex is a versatile product with a wide range of applications. Some of these applications are still undiscovered by contractors, such as sealing concrete mixes. Below are some interesting applications and a brief description of the material itself.

Revinex is a water-based copolymer preparation , specially designed to enhance the properties of cement mortars, plasters, concrete substrates, etc. It is particularly known for its use as a primer for Neoroof and Neoproof PU W-40 , but also, for example, as an additive to external plasters .

What does using Revinex give us in these situations? 

Revinex creates waterproof, durable, and crack-resistant plasters. When used as a base for roofing felt, it closes its pores, reducing the performance of the target material (membrane). One of its most important applications is strengthening the bond between old and new concrete.  

Concrete sealing coating: how to obtain it?

When watertightness is paramount, we recommend coating the substrate with a mixture of 2 parts cement and 1 part Revinex and applying it with a stiff brush . Then, apply the final layer of mortar, also formulated with Revinex. This ensures excellent watertightness . An 11mm , made with a ratio of 1 part cement to 3 parts sand, with approximately 7.5 liters of Revinex added to 50 kg of cement , was subjected to a 30-meter column of water 10 weeks , achieving complete watertightness .

The addition of Revinex to cement-based mixtures results in: 

  • high impermeability to water, 
  • excellent adhesion to various substrates, 
  • the ability to apply thick layers at once, which significantly facilitates application,  
  • increasing abrasion resistance, making floors less dusty 
  • increasing resistance to shrinkage and expansion, thus reducing the risk of cracking,
  • greater resistance to bending and stretching, 
  • reduction of shrinkage (up to 700%) during hardening of the mixture,
  • increased resistance to hydrochloric, lactic and acetic acid.

A key feature of the product is that it reduces the amount of mixing water added by as much as 25% . For example, by adding 7.5kg of Revinex to 50kg of cement, we can reduce the amount of mixing water because Revinex does not dry as quickly as water and allows for longer work with the finished mixture.

The various applications of Revinex® are described in the table below.

For thin layers of screeds/mortars, a higher Revinex addition (from the upper range given in the table above) is recommended . We hope that after reading this article, Revinex will hold no secrets from anyone and will gain new supporters, especially when used as an additive to cement mortars or as a concrete sealant .
