Finale DIY Concrete Countertop System provides an easy to make a real concrete countertop without all the mess and weight of traditional precast concrete countertops. It’s like painting your countertop with concrete.
Finale is typically used to transform outdated laminate countertops to modern concrete. However, it can also be used to restore/refurbish/resurface an old or ugly concrete countertop. After all, Finale is concrete, and it bonds quite well to concrete!
Removing Old Sealer and Contaminants
The most important consideration is surface prep. The concrete must be completely clean and free of oil, grease, dirt, wax, repellants, ANY kind of sealer, or other contaminants.
Unfortunately many old, stained concrete countertops are that way because they were “sealed” with wax or repellent. These substances contaminate the concrete. And even a coating sealer may not have been applied correctly and risks adhesion problems.
Therefore it is best to grind down to bare concrete to ensure that you are removing all such contaminants and underperforming sealers before applying Finale. Very poor quality concrete may need significant grinding to eliminate any flaking or spalling concrete.
Addressing Structural Problems
No microcement topping is capable of repairing structural cracks in concrete. If your concrete is cracked, you should first fill in the crack with epoxy “glue” such as this.
Bear in mind that filling in a crack with epoxy may not fix underlying issues that caused the cracks, like unstable or flimsy cabinets, bouncy floors, etc. These should be addressed and corrected too.
Steps to Restore/Resurface a Concrete Countertop:
1. Grind down to bare concrete
This is exactly the same process described under “Technique 1: Grind down to bare concrete” in the article “How to Reseal Concrete Countertops with Omega“.
2. Clean and dry
After you are done grinding the concrete, it should be thoroughly cleaned and dried, ideally overnight.
3. Fill exposed pinholes with Finale Primer
Grinding any concrete, even the densest, best quality concrete, will expose at least a few pinholes. We recommend that you apply a coat of Finale Primer and use a plastic spatula, pressing to squeegee the Primer into any pinholes. Then apply another coat of Finale Primer.
4. Apply Finale Concrete
At this point you can start applying Finale Concrete. If your primed surface is free of pinholes, you can proceed as normal per the Finale instructions.
If your primed surface still has pinholes, mix up a small amount of Finale Concrete to the consistency of peanut butter and squeegee it into the pinholes as if you were spackling a nail hole in a wall. After that Concrete has dried, you can proceed with normal coats of Finale per the instructions.
5. Seal your concrete countertop
Proceed as usual to the sealing step, but this time use a high quality sealer! For example, view the CCI sealers here.
Restoring an old concrete countertop with a microtopping such as Finale takes some elbow grease and some preparation, but it pays off in the end.
