PRIME SELF-LEVELING MORTAR is a limited flow mortar, incorporating hydraulic cement, fillers and carefully selected additives that provide its unique combination of properties. The compound is ready-to-use after mixing with water. 





PRIME SELF-LEVELING MORTAR bonds tightly with the substrate over the area where it is poured to level all cavities and deformities resulting into a flatter, smooth and level surface. 



PRIME SELF-LEVELING MORTAR gives a new strong-wearing surface that can be used for light, medium, and heavy traffic. It also serves as an underlayment, ready to receive tiles made of PVC, rubber, ceramic, marble, stones, etc. It is great for re-surfacing damaged powdering concrete.

PRIME SELF-LEVELING MORTAR finds usefulness especially for PVC tile-laying. PVC, being flexible, follows the contour of the surface where it is laid. If the substrate is de-formed, non-level or warped, the PVC tile simply conforms to the defects of the substrate and will likewise show the same deformities. Correcting these deformities with PRIME SELF LEVELING MORTAR will result into a level, flat and uniform appearance of the laid PVC tiles. 


The difference between PRIME SELF-LEVELING MORTAR and ordinary concrete used as topping are as follows: 

1. Ordinary concrete does not adhere to the surface of the old concrete, whereas PRIME SELF-LEVELING MORTAR bonds tenaciously

2. Ordinary concrete needs to have at least 2” thickness, PRIME SELF-LEVELING MORTAR may be applied thinly 

3. Ordinary concrete is not as strong as PRIME SELF-LEVELING MORTAR











Surface Preparation 

The concrete surface where PRIME SELF-LEVELING MORTAR is to be applied should be clean and free from loose aggregates, laitance, dust, grease, oil and paint. The presence of such contaminants can jeopardize adhesion. 

1. Clean the surface with the best available method. 

2. Wet the surface with water completely, but remove any excess. It is now ready to receive the PRIME SELF-LEVELING MORTAR


Mix only the approximate amount sufficient to cover the surface area to be corrected. In a bucket, mix just enough water to PRIME SELF-LEVELING MORTAR to bring it to the right consistency. This is done by adding a little amount of water at a time, mixing well with a hand paddle or an electric mixer until there are no more lumps.

The amount of water for a 25 kg bag of PRIME SELF-LEVELING MORTAR is approximately 5.5 liters without segregation. When mixing less than 25 kgs at a time, estimate the approximate amount. 



Pour out the mixed PRIME SELF-LEVELING MORTAR unto the surface. Trowel to a smooth finish. 

Allow the PRIME SELF-LEVELING MORTAR to set undisturbed. Curing time will be at least 4 hours, good for foot only (normal room or ambient temperature) Possible applica-tion of vinyl, after 20-24 hours. 

Since PRIME SELF-LEVELING MORTAR is self-curing, there is no need to water the surface unless the area is very windy or very hot, in which case improper curing might occur. Improper curing is indicated if the surface appears dried up all of a sudden. If this happens, sprinkle water on the surface but do not flood. You can also use PRIMECURE W, a wax based curing compound of PHILPRIME to avoid improper curing of the concrete and formation of cracks.

Store in a cool dry place. Keep the plastic bag unpunctured to prolong the storage life to one year or more. Punctured bags have to be used immediately before the product hardens due to the presence of moisture in the air that reacts with the hydraulic cement of the product. Discard unused product if container is not sealed properly.
