A fluent half-century from Mominul Haque and another composed knock from Mushfiqur Rahim helped the hosts reach 280 for three in their second innings, adding 124 runs in an assertive morning session.
Bangladesh resumed the day in full control and scored freely at a run rate of 4.24. Ireland did manage two breakthroughs, but the momentum never shifted.
Andy McBrine trapped Shadman Islam for 78 with a delivery that thudded into the back pad, and Jordan Neill sent back captain Najmul Hossain Shanto with a sharp, rising ball.
Ireland might have opened the door further had Cade Carmichael held on to a straightforward catch offered by Mushfiqur Rahim at deep backward square. The reprieve proved costly.
Mushfiqur, fresh from his first-innings century, settled quickly and moved into the 40s with characteristic ease.
At the other end, Mominul Haque played with calm precision, reaching his 25th Test half-century. The pair added 106 runs for the fourth wicket, rotating the strike smoothly and punishing anything loose.
Their partnership ensured Bangladesh’s innings continued to build without urgency, and there were no immediate signs of a declaration, reports UNB.
Earlier in the match, Bangladesh posted 476 in their first innings before bowling out Ireland for 265.
