Silicate sealers are commonly used as densifiers to harden and strengthen concrete. Most common applications include concrete that will be polished as seen on many commercial warehouse floors. Silicates also help to prevent dusting, efflorescence, mold and mildew. Keep in mind that silicates are not waterproofers although many manufacturers claim their silicates waterproof, they are strictly densifiers.
Most Important Features When Purchasing a Silicate Sealer:
- Available in either a sodium, potassium or lithium carrier, look for a concentrated blend that will be more cost effective.
- Resistance to mold, mildew, efflorescence, abrasions and dusting.
- Look for an industrial grade silicate with substantial penetration that is chemically reactive with a guaranteed warranty.
