I renovated my kitchen 7 yrs ago and installed Cafe Bahia countertops, I never sealed them and just clean regularly with soapy sponge and water. Hot pans, cutting or water don't seem to affect the surface at all.
They are as shiny as the first day, see link for more details:

Juparana India porosity (water absortion) is 0.2 to 0.3%, seems very low to me. I'd check with your vendor for care recommendation.
