After a deep cleaning, a sealing pavers approach works best, securing sand in the joints, reducing water absorption, and helping preserve the rich color of the deck. Around the pool, it's especially important to consider the porosity of the stone and its exposure to chlorinated water. Careful sealing travertine pavers around pool protects the texture and reduces slippage. Do you choose a sealant with a matte finish or prefer a subtle "wet" sheen?
